Background of the Invention

Protein kinases constitute a large family of structurally related enzymes that are responsible for controlling a wide variety of signal transduction processes within the cell (Hardie, G. and Hanks, S. (1995) The Protein Kinase Facts Book. and II, Academic Press, San Diego, CA). The kinases can be classified into families based on the substrates that they phosphorylate (e.g., protein tyrosine, protein-serine / threonine, lipids, etc.). Sequence motifs corresponding generally to each of these kinase families have been identified (eg, Hanks, SK, Hunter, T., FASEB J., 19: 576-596 (1995); Knighton, et al., Science, 253 , Et al., Cell, 73: 585-596 (1993), Garcia-Bustos, et al. EMBO J., 13: 2352-2361 (1994)).

Protein kinases can be characterized by their regulatory mechanisms. These mechanisms include, for example, autophosphorylation, transphosphorylation by other kinases, protein-protein interactions, protein-lipid interactions and protein-polynucleotide interactions. A particular protein kinase can be regulated by more than one mechanism.

The kinases regulate many different cellular processes including, but not limited to, proliferation, differentiation, apoptosis, mobility, transcription, translation and other signaling processes by the addition of phosphate groups to target proteins. These phosphorylation events act as molecular switches that can modulate or regulate the biological function of the target protein. Phosphorylation of target proteins occurs in response to a variety of extracellular signals (hormones, neurotransmitters, growth and differentiation factors, etc.), cell cycle events, environmental or nutritional stresses, etc. The appropriate protein kinase acts in the signaling pathways to activate or inactivate (directly or indirectly), for example, a metabolic enzyme, regulatory protein, receptor, cytoskeletal protein, ion channel or pump, or transcription factor. Uncontrolled signaling due to poor control of protein phosphorylation has been implicated in a number of diseases, including, for example, inflammation, cancer, allergy / asthma, diseases and conditions of the immune system, diseases and conditions of the central nervous system, and angiogenesis. The process of dividing the eukaryotic cells can be broadly divided into a series of sequential phases designated Gl, S, G2 and M. It has been shown that the correct progression through the various phases of the cell cycle depends critically on the regulation spatial and temporal association of a family of proteins known as cyclin-dependent kinases (CDK) and a varied set of their cognate partners of the protein termed cyclins. CDKs are cdc2 homologous serine-threonine kinase proteins (also known as CDK1) which are capable of using ATP as a substrate in the phosphorylation of various polypeptides in a context dependent sequence. Cyclins are a family of proteins characterized by a region of homology, containing approximately 100 amino acids, referred to as " cyclin box " which is used in the binding, and which defines selectivity for specific CDK partner proteins. Modulation of expression levels, degradation rates and activation levels of various CDKs and cyclins throughout the cell cycle leads to the cyclic formation of a series of CDK / cyclin complexes in which CDKs are enzymatically active. The formation of these complexes controls the passage through discrete cell cycle control points and thereby allows the cell division process to proceed. Failure to meet the prerequisite biochemical criteria at a given cell cycle control point, i. and. the failure to form a required CDK / cyclin complex can lead to cell cycle arrest and / or cellular apoptosis. Aberrant cell proliferation, as manifested in cancer, can often be attributed to loss of correct cell cycle control. Accordingly, inhibition of the enzymatic activity of CDK provides a means by which abnormally dividing cells 3 may have their division arrested and / or killed. The variety of CDKs, and CDK complexes, and their critical roles in cell cycle mediation provide a broad spectrum of potential therapeutic targets selected based on a defined biochemical rationale. The progression from G1 phase to S phase of the cell cycle is mainly regulated by CDK2, CDK3, CDK4 and CDK6 through association with members of D-type and E-cyclins. D-type cyclins appear to be determinant to allow passage beyond restriction site Gl, while the CDK2 / cyclin E complex is key to the transition from the G1 phase to the S. It is believed that the subsequent progression through the S phase and the G2 entry requires the CDK2 / cyclin A complex. Mitosis, and the transition from the G2 phase to the triggering M, are regulated by CDK1 complexes and the cyclins type A and B.

During Gl phase the Retinoblastoma protein (Rb) and related cavity proteins such as pl30 are substrates for the CDK (2,4,4 & 6) / cyclin complexes. Progression through Gl is in part facilitated by hyperphosphorylation and, thus, by inactivation, of Rb and p30 by the CDK (4/6) / cyclin-D complexes. Hyperphosphorylation of Rb and p30 causes the release of transcription factors, such as E2F, and thereby the expression of genes required for progression through Gl and for entry into the S phase, such as the gene for cyclin E. Expression of cyclin E facilitates the formation of the CDK2 / cyclin E complex, which increases or maintains E2F levels through the additional phosphorylation of Rb. The CDK2 / cyclin E complex also phosphorylates other proteins required for DNA replication, such as NPAT that has been implicated in histone biosynthesis. The progression of Gl and 4 to the Gl / S transition are also regulated via the mitogen stimulated Myc pathway, which enters the CDK2 / cyclin E pathway. CDK2 is also related to the p53-mediated DNA damage response pathway through the regulation of p21 levels by p53. P21 is a CDK2 / cyclin E protein inhibitor and is thus capable of blocking or retarding the Gl / S transition. The CDK2 / cyclin E complex may thus represent a point at which the biochemical stimuli of the Rb, Myc and p53 pathways are to some extent integrated. Therefore, CDK2 and / or CDK2 / cyclin E complex represent good targets for therapies designed to stop or regain control of the cell cycle in aberrant cell division. The exact role of CDK3 in the cell cycle is not clear. To date, no cognate cyclin partner has been identified, but a dominant negative form of CDK3 delays the cells in Gl, thereby suggesting that CDK3 plays a role in regulating the Gl / S transition.

Although most CDKs have been implicated in cell cycle regulation, there is evidence that certain members of the CDK family are involved in other biochemical processes. This is exemplified by CDK5 which is required for correct neuronal development and which has also been implicated in the phosphorylation of various neuronal proteins, such as Tau, NUDE-1, synapsinal, DARPP32 and the Muncl8 / SyntaxinalA complex. Neuronal CDK5 is conventionally activated by binding to p35 / p39 proteins. However, CDK5 activity can be deregulated by the binding of p25, a truncated version of ρ35. Conversion of p35 into p25, and subsequent dysregulation of CDK5 activity, can be induced by ischemia, excitotoxicity and β-amyloid peptide. Accordingly, p255 has been implicated in the pathogenesis of neurodegenerative diseases, such as Alzheimer's and is therefore of interest as a target for therapeutics directed against these diseases. CDK7 is a nuclear protein having cdc2 CAK activity and binding to cyclin Η. CDK7 has been identified as a component of the TFIIH transcription complex, which has the C-terminal domain (CTD) activity of RNA polymerase II. This was associated with the regulation of HIV-1 transcription via a Tat-mediated biochemical pathway. CDK8 binds cyclin C and was implicated in CTD phosphorylation of RNA polymerase II. Similarly, the CDK9 / cyclin-T1 complex (P-TEFb complex) was involved in the control of RNA polymerase II elongation. PTEF-b is also required for the activation of HIV-1 genome transcription by Tat transactivator Tat through its interaction with cyclin T1. CDK7, CDK8, CDK9 and the P-TEFb complex are therefore potential targets for antiviral therapies.

At a molecular level, mediation of the CDK / cyclin complex activity requires a series of phosphorylation or dephosphorylation events, stimulators and inhibitors. CDK phosphorylation is performed by a group of CDK activating kinases (CAKs) and / or kinases, such as weel, Mytl and Mikl. Dephosphorylation is performed by phosphatases, such as cdc25 (a & c), pp2a or KAP. The CDK / cyclin complex activity can further be regulated by two families of endogenous cellular protein inhibitors: the Kip / Cip family or the INK family. INK proteins specifically bind CDK4 and CDK6. Pl6ink4 (also known as MTS 1) is a potential tumor suppressor gene that is mutated, or deleted, in a large number of primary cancers. The Kip / Cip family contains proteins, such as p21Cipl'Wafl, p27Kipl and p57Kip2. As discussed previously, p21 is induced by p53 and is capable of inactivating the CDK2 / cyclin (E / A) and CDK4 / cyclin complexes (D1 / D2 / D3). Atypically low levels of p27 expression were observed in breast, colon and prostate cancers. In contrast, overexpression of cyclin E in solid tumors has been shown to correlate with a poor prognosis for the patient. Cyclin D1 overexpression was associated with esophageal, breast, squamous and non-small cell lung carcinomas.

The essential roles of CDK and its associated proteins in the coordination and conduction of the cell cycle in proliferating cells have been outlined above. Some of the biochemical pathways in which CDKs play a key role have also been described. The development of monotherapies for the treatment of proliferative disorders, such as cancers, using generically targeted therapies for CDK, or for specific CDKs is therefore potentially very desirable. Possibly, CDK inhibitors could also be used to treat other conditions, such as viral infections, autoimmune diseases and neurodegenerative diseases, among others. Targeted therapies for CDK may also provide clinical advantages in treating the previously described diseases when used in combination therapy with existing or novel therapeutic agents. Potentially, anticancer therapies directed to CDK could have advantages over many standard antitumor agents since they would not interact directly with DNA and would therefore reduce the risk of secondary tumor development. 7 Glycogen synthase-kinase-3 (GSK3) is a serine-threonine kinase that occurs as two ubiquitously expressed isoforms in humans (GSK3o & beta3Κ3β). GSK3 has been implicated as having roles in embryonic development, protein synthesis, cell proliferation, cell differentiation, microtubule dynamics, cell motility and cellular apoptosis. As such, GSK3 has been implicated in the progression of disease states, such as diabetes, cancer, Alzheimer's disease, stroke, epilepsy, motor neuron disease and / or head trauma. Phylogenetically, GSK3 is very closely related to cyclin-dependent kinases (CDK). The consensus sequence of the peptide substrate recognized for GSK3 is (Ser / Thr) -XXX- (pSer / pThr), where X is any amino acid (at positions n + 1, n + 2, n + 3 )) and pSer and pThr are phosphoserine and phosphotreonine, respectively (n + 4). The GSK3

phosphorylates the first serine, or threonine, in position (n). The phosphoserine, or phosphotreonine, at the (n + 4) position appears to be necessary to prepare the GSK3 to give maximum cyclization of the substrate. The phosphorylation of GSK3a on Ser21, or ΰ3Κ3β on Ser9, leads to inhibition of GSK3. Mutagenesis and competition studies of peptides have led to the model that the phosphorylated N-terminal end of GSK3 is able to compete with the phosphopeptide substrate (S / TXXXpS / pT) through an auto-inhibiting mechanism. There is also evidence suggesting that GSK3cx and

ΰ3Κ3β may be subtly regulated by phosphorylation of tyrosines 279 and 216, respectively. Mutation of these residues in a Phe resulted in a reduction of the kinase activity in vivo. The X-ray crystallographic structure of ΰ3Κ3β helped to shed light on all aspects of the activation and regulation of GSK3. GSK3 is part of the mammalian insulin response pathway and is capable of phosphorylating and thereby inactivating glycogen synthase. Positive regulation of glycogen synthase activity and hence glycogen synthesis through inhibition of GSK3 has thus been considered as a potential means to combat type II or non-insulin dependent diabetes mellitus (NIDDM): a condition in which body tissues become resistant to stimulation by insulin. The cellular response to insulin in the hepatic, adipose or muscular tissues is triggered by the binding of insulin to an extracellular insulin receptor. This leads to phosphorylation, and subsequent recruitment to the plasma membrane, of the insulin receptor substrate (IRS) proteins. Further phosphorylation of IRS proteins initiates the recruitment of phosphoinositide-3-kinase (PI3K) to the plasma membrane where it is able to release the secondary messenger phosphatidylinositol 3,4,5-trisphosphate (PIP3). This facilitates the co-localization of 3-phosphoinositide (PDK1) -dependent protein kinase 1 and protein kinase B (PKB or Akt) to the membrane, where PDK1 activates PKB. PKB is capable of phosphorylating and thereby inhibiting GSK3a and / or GS1 by phosphorylation of Ser9, or ser21, respectively. Inhibition of GSK3 then triggers the positive regulation of glycogen synthase activity. Therapeutic agents capable of inhibiting GSK3 may thus be capable of inducing cellular responses analogous to that observed in insulin stimulation. Another in vivo substrate of GSK3 is the eukaryotic initiator of protein synthesis 2B (eIF2B). The eIF2B is inactivated by phosphorylation and is thus capable of suppressing protein biosynthesis. Inhibition of GSK3, e.g. by inactivation of the " target protein " of rapamycin in mammals " (mTOR), can thus positively regulate protein biosynthesis. Finally, there is some evidence for the regulation of GSK3 activity by the mitogen-activated protein kinase (MAPK) pathway through the phosphorylation of GSK3 by kinases such as mitogen-activated protein kinase-activated protein kinase 1 (MAPKAP-K1 or RSK). These data suggest that GSK3 activity can be modulated by mitogen, insulin and / or amino acid stimuli.

It has also been shown that GSK3P is a key component in the Wnt signaling pathway of vertebrates. It has been shown that this biochemical pathway is critical for normal embryonic development and regulates cell proliferation in normal tissues. GSK3 is inhibited in response to Wnt stimuli. This may lead to dephosphorylation of GSK3 substrates, such as Axin, the genetic product of adenomatous coli polyposis (APC) and β-catenin. Aberrant regulation of the Wnt pathway has been associated with many cancers. Mutations in APC and / or β-catenin are common in colorectal cancer and other tumors. Β-catenin has also been shown to be important in cell adhesion. Thus, GSK3 can also modulate cell adhesion processes to some extent. In addition to the biochemical pathways already described, there are also data implicating GSK3 in the regulation of cell division through cyclin-D1 phosphorylation, in the phosphorylation of transcription factors such as c-Jun, CCAAT binding protein / enhancer (C / ), c-Myc and / or other substrates, such as Activated T-Cell Nuclear Factor (NFATc), Thermal Shock Factor-1 (HSF-1) and c-AMP response element binding protein (CREB ). GSK3 also appears to play a role, though tissue-specific, in the regulation of cellular apoptosis. The role of GSK3 in the modulation of cellular apoptosis through a pro-apoptotic mechanism may be particularly relevant for clinical conditions in which neuronal apoptosis may occur. 10 examples of these are head trauma, stroke, epilepsy, Alzheimer's and motor neuron diseases, progressive supranuclear palsy, corticobasal degeneration and Pick's disease. In vitro it has been shown that GSK3 is capable of hyperphosphorylating the Tau protein associated with the microtubule. Tau hyperphosphorylation disrupts its normal binding to microtubules and can also lead to the formation of intracellular Tau filaments. It is thought that the progressive accumulation of these filaments leads to eventual dysfunction and neuronal degeneration. Inhibition of Tau phosphorylation, through inhibition of GSK3, can thus provide a means to limit and / or prevent neurodegenerative effects.

References to " carbocyclic " and " heterocyclic " as used herein shall, unless the context otherwise indicates, include aromatic and non-aromatic ring systems. Thus, for example, the term " carbocyclic and heterocyclic groups " includes within its scope non-aromatic, unsaturated, partially saturated and fully saturated aromatic carbocyclic and heterocyclic ring systems. In general, such groups may be monocyclic or bicyclic and may contain, for example, 3 to 12 ring members, more generally 5 to 10 ring members. Examples of monocyclic groups are 3-, 4-, 5-, 6-, 7- and 8-membered endocyclic groups, more generally 3 to 7, and preferably 5 or 6 endocyclic members. Examples of bicyclic groups are those containing 8, 9, 10, 11 and 12 endocyclic members, and more generally 9 or 10 endocyclic members.

Carbocyclic or heterocyclic groups may be aryl or heteroaryl groups having from 5 to 12 ring members, more generally from 5 to 10 ring members. The term " aryl " as used herein refers to a carbocyclic group having aromatic character and the term " heteroaryl " is used herein to denote a heterocyclic group having aromatic character. The terms " aryl " and " heteroaryl " encompass polycyclic (e.g., bicyclic) ring systems wherein one or more rings are non-aromatic, with the proviso that at least one ring is aromatic. In such polycyclic systems, the group may be attached by the aromatic ring or a non-aromatic ring. The aryl or heteroaryl groups may be monocyclic or bicyclic groups and may be unsubstituted or substituted with one or more substituents, for example one or more R 10 groups as defined herein. The term " non-aromatic group " comprises non-aromatic unsaturated ring systems, partially saturated and fully saturated carbocyclic and heterocyclic ring systems. The terms " unsaturated " and " partially saturated " refer to rings in which the ring structure or structures contain atoms that share binding with more than one valence, i. the ring contains at least one multiple bond, e.g. a C = C, C = C or N = C bond. The term " fully saturated " refers to rings where there are no multiple bonds between endocyclic atoms. The saturated carbocyclic groups include cycloalkyl groups as defined below.

Each ring may contain up to about four heteroatoms typically selected from nitrogen, sulfur and oxygen. Typically the heteroaryl ring will contain up to 4 heteroatoms, more typically up to 3 heteroatoms, more generally up to 2, for example, a single heteroatom. In one embodiment, the heteroaryl ring contains at least one endocyclic nitrogen atom. The nitrogen atoms in the heteroaryl rings may be basic, as in the case of an imidazole or pyridine, or essentially non-basic as in the case of an indole or pyrrole nitrogen. In general, the number of basic nitrogen atoms present in the heteroaryl group, including any ring substituent amino groups, will be less than five.

A subset of non-aromatic carbocyclic groups include unsubstituted or substituted monocyclic groups (with one or more R 10 groups) and particularly saturated monocyclic groups, e.g. cycloalkyl groups. Examples of such cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl; more typically cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl, particularly cyclohexyl.

Other examples of non-aromatic cyclic groups include bridged ring systems, such as bicycloalkanes and azabicycloalkanes, although such bridging ring systems are generally less preferred. By " bridged ring systems " it is intended to refer to ring systems in which two rings share more than two atoms, see for example, Advanced Organic Chemistry, by Jerry March, 4th Edition, Wiley Interscience, pages 131-133, 1992. Examples of ring systems in bridge include bicyclo [2.2.1] heptane, aza-bicyclo [2.2.1] heptane, bicyclo [2.2.2] octane, aza-bicyclo [2.2.2] octane, bicyclo [3.2.1] octane and aza-bicyclo [ 3.2.1] octane. A particular example of a bridging ring system is the 1-aza-bicyclo [2.2.2] octan-3-yl group.

When reference is made herein to carbocyclic and heterocyclic groups, the carbocyclic or heterocyclic ring may, unless the context indicates otherwise, be unsubstituted or substituted with one or more substituent groups R10 selected from halogen, hydroxy, trifluoromethyl, cyano, nitro , carboxy, amino, mono- or dihydrocarbylamino C1-4, carbocyclic and heterocyclic groups having from 3 to 12 ring members; a group Ra-Rb wherein Ra is a bond, O, CO, X1, X2), C (X2) X1, X1, S, SO, SO2, NRC, SO2 NRc or NRcS02; and Rb is selected from hydrogen, carbocyclic and heterocyclic groups having from 3 to 12 ring members, and a C1-8 hydrocarbyl group optionally substituted with one or more substituents selected from hydroxy, oxo, halogen, cyano, nitro, carboxyl, amino, mono- or dihydrocarbylamino, C1-3 carbocyclic and heterocyclic groups having from 3 to 12 ring members and wherein one or more C1-8 hydrocarbyl carbon atoms may be optionally substituted with O, S, SO, SO2, NRC, X1C (XZ), C (X 2) X 1 or X 1 C (X 2) X 1;

Rc is selected from hydrogen and C1-4 hydrocarbyl; and X 1 is O, S or NRC and X 2 is = O, = S or = NRC.

When the substituent group R 10 comprises or includes a carbocyclic or heterocyclic group, said carbocyclic or heterocyclic group may be unsubstituted or may itself be substituted by one or more other substituent groups R 10. In a subgroup of compounds of formula (II), such other substituent groups R 10 may include carbocyclic or heterocyclic groups, which typically are not themselves further substituted. In another subgroup of compounds of formula (II), said other substituents do not include carbocyclic or heterocyclic groups but are otherwise selected from the groups listed above in the definition of R 10.

The substituents R 10 may be selected such that they contain not more than 20 non-hydrogen atoms, for example not more than 15 different hydrogen atoms, e.g. not more than 12, or 11, or 10, or 9, or 8, or 7, or 6, or 5 different hydrogen atoms.

When the carbocyclic and heterocyclic groups have a pair of substituents on adjacent ring atoms, the two substituents may be attached to form a cyclic group. Thus, two adjacent R10 groups together with the 34 carbon atoms or heteroatoms to which they are attached may form a 5-membered heteroaryl ring or a 5- or 6-membered non-aromatic carbocyclic or heterocyclic ring, wherein said heteroaryl and heterocyclic ring containing up to 3 heteroatom ring members selected from N, O and S. For example, a pair of adjacent substituents on adjacent carbon atoms of a ring may be attached through one or more optionally substituted heteroatoms and alkylene groups to form a oxa-, dioxa-, aza-, diaza- or oxa-aza-cycloalkyl.

Examples of such joined substituent groups include:

Examples of halogen substituents include fluoro, chloro, bromo and iodo. Fluorine and chlorine are particularly preferred.

In the definition of the above compounds of formula (II) and as used below, the term " hydrocarbyl " is a generic term encompassing aliphatic, alicyclic and aromatic groups having a fully carbon skeleton and consisting of carbon and hydrogen atoms, unless otherwise indicated. 35

The examples and preferences expressed below, apply to each of the hydrocarbyl-substituent groups or hydrocarbyl-containing substituent groups referred to in the various definitions of substituents for the compounds of formula (II) unless otherwise indicated in the context.

Preferred non-aromatic hydrocarbyl groups are saturated groups, such as alkyl and cycloalkyl groups.

Preferred substituents include halogens such as fluorine. Thus, for example, the substituted hydrocarbyl group may be a partially fluorinated or perfluorinated group such as difluoromethyl or trifluoromethyl. In one embodiment, preferred substituents include monocyclic carbocyclic and heterocyclic groups having 3-7 ring members, more generally 3, 4, 5 or 6 ring members.

Where specified, one or more carbon atoms of a hydrocarbyl group may be optionally substituted with O, S, SO, SO 2, NRC, X 2 C (X 2), C (X 2) X 1 or X 1 C (X 2) X 1 (or a subgroup thereof ) wherein X 1 and X 2 are as defined above, with the proviso that at least one carbon atom of the hydrocarbyl group remains. For example, 1, 2, 3 or 4 carbon atoms of the hydrocarbyl group may be substituted with one of the listed atoms or groups, and the substituent atoms or groups may be the same or different. In general, the number of linear carbon atoms or the skeleton substituted, will correspond to the number of linear atoms or the skeleton in the group that substitutes them. Examples of groups in which one or more carbon atoms of the hydrocarbyl group have been replaced with a substituent atom or group as defined above include ethers and thioethers (C- or S-substituted C), amides, esters, thioamides and thioesters (X 2) or C (X 2) X 1), sulfones and sulfoxides (C substituted with SO or SO 2), amines (NRC substituted C).

Thus, examples of aza-cycloalkyl groups include piperidine and pyrrolidine. The term " oxa-cycloalkyl " as used herein refers to a cycloalkyl group wherein one of the carbon endocyclic members has been replaced with an oxygen atom. Thus, examples of oxa-cycloalkyl groups include tetrahydrofuran and tetrahydropyran. Similarly, the terms " diaza-cycloalkyl " " dioxa-cycloalkyl " and " aza-oxa-cycloalkyl " refer respectively to cycloalkyl groups in which two carbon endocyclic members have been substituted with two nitrogen atoms, or two oxygen atoms, or one nitrogen atom and one oxygen atom.

Prodrugs and Isotopes

Unless otherwise noted, a reference to a particular compound also includes the ionic, salt, solvate protected forms thereof, for example, as discussed below.

Many compounds of formula (II) may exist in the form of salts, for example acid addition salts or, in some cases, salts of organic and inorganic bases, such as carboxylate, sulfonate and phosphate salts. All such salts are within the scope of this invention and references to compounds of formula (II) include the salt forms of the compounds. As in the previous sections of this application, all references to formula (II) are to be taken to refer also to formulas (IV), (IVa), (Va), (Vb), (Way) or (VIb) and to their subgroups, unless the context indicates otherwise.

The salt forms may be selected and prepared according to methods described in Pharmaceutical Salts: Properties, Selection, and Use, P. Heinrich Stahl (Editor), Camille G. Wermuth (Editor), ISBN: 3-90639-026-8 , hardcover book, 388 pages, August 2002.

The acid addition salts may be prepared with a wide variety of inorganic and organic acids. Examples of acid addition salts include salts prepared with an acid selected from the group consisting of acetic, 2,2-dichloroacetic, adipic, alginic, ascorbic (eg, L-ascorbic), L-aspartic, benzenesulfonic, benzoic, 4- (S) -camphor-10-sulfonic, capric, caproic, caprylic, cinnamic, citric, cyclic, dodecylsulfuric, ethane-1,2-disulphonic, ethanesulphonic, ethanesulphonic, Glucuronic (eg, D-glucuronic), glutamic (eg, L-glutamic), α-oxoglutaric, glycolic, hippuric, hydrobromic, hydrochloric, hydrobromic, hydrobromic, (±) -L-lactic, (±) -DL-lactic, lactobionic, maleic, malic, (-) -L-malic, malonic, (±) -DL-mandelic, methanesulfonic, naphthalene-2- naphthalene-1,5-disulfonic, 1-hydroxy-2-naphthoic, nicotinic, nitric, oleic, ortho (+) - L-tartaric, thiocyanic, p-toluenesulfonic, undecylenic and unsubstituted aminocarbonyl groups, such as, for example, sodium, potassium, propyl, valeric, as well as acylated amino acids and cation exchange resins.

A particular group of salts consists of salts prepared from hydrochloric, hydroiodic, phosphoric, nitric, sulfuric, citric, lactic, succinic, maleic, malic, isethionic, fumaric, benzenesulfonic, toluenesulfonic, methanesulfonic, ethanesulfonic, naphthalenesulfonic, valeric, acetic , propanoic, butanoic, malonic, glucuronic and lactobionic acids.

A preferred group of salts consists of salts prepared from hydrochloric, acetic, adipic, L-aspartic and DL-lactic acids.

Particularly preferred salts are hydrochloride salts.

For example, if the compound is anionic, or has a functional group which may be anionic (e.g., -COOH may be -COO-), then a salt with a suitable cation may be prepared. Examples of suitable inorganic cations include, but are not limited to, alkali metal ions such as Na + and K +, alkaline earth cations such as Ca 2+ and Mg 2+, and other cations such as Al 3+. Examples of suitable organic cations include, but are not limited to, ammonium ion (i.e., NH4 +) and substituted ammonium ions (e.g., NH3R +, NH2R2 +, NHR3 +, NR4 +). Examples of some suitable substituted ammonium ions are those derived from: ethylamine, diethylamine, dicyclohexylamine, triethylamine, butylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine, benzylamine, phenylbenzylamine, choline, meglumine and tromethamine, as well as amino acids such as lysine and arginine. An example of a common quaternary ammonium ion is N (CH 3) 4+.

When the compounds of the formula (II) contain an amine function, they may form quaternary ammonium salts, for example by reaction with an alkylating agent according to methods well known to the person skilled in the art. Such quaternary ammonium compounds are within the scope of formula (II).

The salt forms of the compounds of the invention are typically pharmaceutically acceptable salts, and examples of pharmaceutically acceptable salts are discussed in Berge et al., 1977, " Pharmaceutically Acceptable Salts ", J. Pharm. Sci., Vol. 66, pp. 1-19. However, salts which are not pharmaceutically acceptable may also be prepared as intermediate forms which may then be converted into pharmaceutically acceptable salts. Such non-pharmaceutically acceptable salt forms, which may be useful, for example, in the purification or separation of the compounds of the invention, also form part of the invention. 92

Compounds of formula (II) containing an amine function may also form N-oxides. Reference herein to a compound of formula (II) which contains an amine function also includes N-oxide.

When a compound contains several amine functions, one or more than one nitrogen atom may be oxidized to form an N-oxide. Particular examples of N-oxides are the N-oxides of a tertiary amine or a nitrogen atom of a nitrogen-containing heterocycle.

The N-oxides may be prepared by treatment of the corresponding amine with an oxidizing agent, such as hydrogen peroxide or a peracid (eg, peroxycarboxylic acid), see for example, Advanced Organic Chemistry, Jerry March, 4th Edition, Wiley Interscience, pages. More particularly, the N-oxides can be prepared by the method of LW Deady (Syn. Comm. 1977, 7, 509-514) in which the amine compound is reacted with m-chloroperoxybenzoic acid (MCPBA), for example, inert solvent such as dichloromethane.

The compounds of formula (II) may exist in a number of different geometric and tautomeric isomeric forms and references to compounds of formula (II) include all such forms. For the avoidance of doubt, when a compound can exist in one of several geometric or tautomeric isomeric forms and is only specifically described or shown one, all the others are nevertheless encompassed by formula (II).

For example, in the compounds of formula (II), the pyrazole group may obtain any one of the following two tautomeric forms A and B (wherein X represents R 1 (CO) NH). To facilitate, general formula (II) illustrates Form A but the formula is to be considered as encompassing both tautomeric forms.

Further examples of tautomeric forms include, for example, the keto, enol and enolate forms, for example, in the following tautomeric moieties: keto / enol (shown below), imine / enamine, amide / iminoalcohol, amidine / amidine, oxime, thioketone / enetiol, and nitro / acyl-nitro. C c-C c-C c or C c-C x-C +-C +-C +-C +-C +-C +-C +-C +-C +-C en-enol enolate

When the compounds of formula (II) contain one or more chiral centers, and may exist as two or more optical isomers, references to compounds of formula (II) include all isomeric optical forms thereof (eg, enantiomers, epimers, and diastereomers), as individual optical isomers, or mixtures (eg, racemic mixtures) or two or more optical isomers, unless the context otherwise requires. 94

Optical isomers can be characterized and identified by their optical activity (i.e. as + and - isomers or d isomers 1) or can be characterized in terms of their absolute stereochemistry using the nomenclature " R " developed by Cahn, Ingold and Prelog, see Advanced Organic Chemistry of Jerry March, 4th Edition, John Wiley & Sons, Nova

York, 1992, pages 109-114, and see also Cahn, Ingold & Prelog, Angew. Chem. Int. Ed. Engl., 1966, 5, 385-415.

Optical isomers can be separated by a number of techniques including chiral chromatography (chromatography on a chiral support) and such techniques are well known to the person skilled in the art.

When the compounds of formula (II) exist as two or more optical isomeric forms, one enantiomer in one pair of enantiomers may exhibit advantages over the other enantiomer, for example in terms of biological activity.

Thus, in certain circumstances, it may be desirable to use as a therapeutic agent only one of a pair of enantiomers, or only one of a multiplicity of diastereoisomers. Accordingly, the invention provides compositions containing a compound of formula (II) having one or more chiral centers, wherein at least 55% (eg, at least 60%, 65%, 70%, 75%, 80%, 85% , 90% or 95%) of the compound of formula (II) is present as a single optical isomer (eg, enantiomer or diastereoisomer). In a general embodiment, 99% or more (e.g., substantially all) of the total amount of the compound of formula (II) may be present as a single optical isomer (e.g., enantiomer or diastereoisomer). 95

The compounds of the invention include compounds with one or more isotopic substitutions and a reference to a particular element includes within it all the isotopes of the element. For example, a reference to hydrogen includes within its scope ΧΗ, 2H (D), and 3H (T). Similarly, references to carbon and oxygen include within their scope 12C, 13C and 14C and 60O and 180, respectively.

The isotopes may be radioactive or non-radioactive. In one embodiment of the invention, the compounds do not have any radioactive isotopes. Such compounds are preferred for therapeutic use. In another embodiment, however, the compound may contain one or more radioisotopes. Compounds containing such radioisotopes may be useful in a diagnostic setting.

Esters such as the carboxylic acid esters and acyloxyl esters of the compounds of formula (II) having a carboxylic acid group or a hydroxyl group are also encompassed by Formula (II). Examples of esters are compounds containing the group -C (= O) OR, where R is an ester substituent, for example, a C1-7 alkyl group, a C3-20 heterocyclyl group or a C5-20 aryl group, preferably a C1-7 alkyl group. Particular examples of ester groups include, but are not limited to, -C (= O) OCH 3, -C (= O) OCH 2 CH 3, -C (= O) OC (CH 3) 3 and -C (= O) O Ph. Examples of acyloxy groups (inverse ester) are represented by -OC (= O) R, where R is an acyloxy substituent, for example, a C 1-7 alkyl group, a C 3-10 heterocyclyl group or a C 5-7 aryl group in a manner Preferred is a C1-7 alkyl group. Particular examples of acyloxyl groups include, but are not limited to, -OC (= O) CH3 96 (acetoxy), -OC (= O) CH2 Ph. 0C (= O) CH 2 CH 3, 0C (= O) C (CH 3) 3, -OC (= O) Ph e

Also encompassed by formula (II) are any polymorphic forms of the compounds, solvates (e.g., hydrates) and complexes (e.g., inclusion complexes or clathrates with compounds, such as cyclodextrins, or complexes with metals) of the compounds. For example, some prodrugs are esters of the active compound (e.g., a physiologically acceptable metabolically unstable ester). During metabolism, the ester group (-C (= O) OR) is cleaved to produce the active drug. Such esters may be prepared by esterifying, for example, any of the carboxylic acid groups (-C (= O) OH) in the parent compound with, where appropriate, prior protection of any other reactive groups present in the parent compound, followed by deprotection if required.

Examples of such metabolically unstable esters include those of the formula -C (= O) O R wherein R 1 is C 1-7 -alkyl (eg, -Me, -Et, -nPr, -iPr, -nBu, -sBu, -iBu, - tBu); C1-7 aminoalkyl (e.g., aminoethyl; 2- (N, N-diethylamino) ethyl; 2- (4-morpholino) ethyl); and acyloxy-C1-7 alkyl (eg, acyloxymethyl, acyloxyethyl, pivaloyloxymethyl, acetoxymethyl, 1-acetoxyethyl, 1- (1-methoxy-1-methyl) ethylcarbonyloxyethyl, 1- (benzoyloxy) ethyl, isopropoxycarbonyloxymethyl, 1-isopropoxy (4-tetrahydropyranyloxy) carbonyloxymethyl, 1- (4-tetrahydropyranyloxy) cyclohexylcarbonyloxymethyl, 1-cyclohexylcarbonyloxyethyl, 1-cyclohexyloxycarbonyloxymethyl, 1-cyclohexyloxycarbonyloxymethyl, ) carbonyloxyethyl; (4-tetrahydropyranyl) carbonyloxymethyl; and 1- (4-tetrahydropyranyl) carbonyloxyethyl).

Also, some prodrugs are enzymatically activated to produce the active compound, or a compound which upon subsequent chemical reaction produces the active compound (for example, as in ADEPT, GDEPT, LIDEPT, etc.). For example, the prodrug may be a derived sugar or other conjugated glycoside, or may be an amino acid ester derivative.

Biological Activity

The compounds of the formulas (II), (IV), (IVa), (Va), (Vb), (Via) or (VIb) and their subgroups are inhibitors of cyclin-dependent kinases, and in particular selected cyclin-dependent kinases of CDK1, CDK2, CDK3, CDK4, CDK5 and CDK6.

Preferred compounds are compounds which inhibit one or more CDK kinases selected from CDK1, CDK2, CDK4 and CDK5, for example, CDK1 and / or CDK2.

The compounds of the invention are also considered to be glycogen synthase kinase-3 (GSK3) inhibitors. 98

As a consequence of their activity in modulating or inhibiting CDK kinases and glycogen synthase kinase they are expected to be useful in providing a means of stopping or regaining control of the cell cycle in abnormal dividing cells. Accordingly, it is anticipated that the compounds will be useful in the treatment or prevention of proliferative disorders, such as cancers. It is also envisaged that the compounds of the invention will be useful in treating conditions such as, for example, viral infections, type II or non-insulin dependent diabetes mellitus, autoimmune diseases, head trauma, stroke, epilepsy, neurodegenerative disorders such as Alzheimer's, motor neuron disease, progressive supranuclear palsy, corticobasal degeneration and Pick's disease. A subgroup of conditions and pathological conditions in which the compounds of the invention are expected to be useful consists of viral infections, autoimmune diseases and neurodegenerative diseases.

CDKs play a role in cell cycle regulation, apoptosis, transcription, differentiation and CNS function. Accordingly, CDK inhibitors could be useful in the treatment of diseases in which there is a disorder of proliferation, apoptosis or differentiation such as cancer. In particular, RB + tumors may be particularly sensitive to CDK inhibitors. RB-vo tumors may also be sensitive to CDK inhibitors.

Examples of cancers that may be inhibited include, but are not limited to, a carcinoma, e.g. a bladder, breast, colon carcinoma (eg, colorectal carcinomas such as colon adenocarcinoma and colon adenoma), kidney, epidermis , liver, lung, e.g., adenocarcinoma, small cell lung cancer, and non-small cell lung carcinomas, esophagus, gallbladder, ovary, pancreas, e.g. exocrine pancreatic carcinoma, stomach, cervix, thyroid, prostate or skin, for example, squamous cell carcinoma; a hematopoietic lymphoid lineage tumor, for example, leukemia, acute lymphocytic leukemia, B-cell lymphoma, T-cell lymphoma, Hodgkin's lymphoma, non-Hodgkin's lymphoma, trichocellin lymphoma or Burkett's lymphoma; a hematopoietic tumor of myeloid lineage, for example, acute and chronic myeloid leukemias, myelodysplastic syndrome or promyelocytic leukemia; thyroid follicular cancer; a tumor of mesenchymal origin, for example fibrosarcoma or rhabdomyosarcoma, a tumor of the central or peripheral nervous system, for example, astrocytoma, neuroblastorna, glioma or schwannoma; melanoma; seminoma; teratocarcinoma; osteosarcoma; xeroderma pigmentosum; keratoacanthoma; thyroid follicular cancer; or Kaposi's sarcoma.

Cancers can be cancers that are sensitive to inhibition of any of the cyclin dependent kinases selected from CDK1, CDK2, CDK3, CDK4, CDK5 and CDK6, for example, one or more CDK kinases selected from CDK1, CDK2, CDK4 and CDK5, and. CDK1 and / or CDK2.

Whether or not a particular cancer is one that is sensitive to inhibition by a cyclin-dependent kinase can be determined by means of a cell growth assay as indicated in Example 250 below or by a method as indicated in the section entitled " Methods of Diagnosis ".

CDKs are also known to play a role in apoptosis, proliferation, differentiation and transcription, and therefore CDK inhibitors could also be useful in treating the following diseases other than cancer; viral infections, for example, herpes viruses, smallpox virus, Epstein-Barr virus, Sindbis virus, adenovirus, HIV, HPV, HCV and HCMV; prevention of AIDS development in HIV-infected individuals; chronic inflammatory diseases, for example, disseminated lupus erythematosus, autoimmune mediated glomerulonephritis, rheumatoid arthritis, psoriasis, inflammatory bowel disease and autoimmune diabetes mellitus; cardiovascular diseases, for example, cardiac hypertrophy, restenosis, atherosclerosis; neurodegenerative disorders, for example, Alzheimer's disease, AIDS-related dementia, Parkinson's disease, amyotrophic lateral sclerosis, retinitis pigmentosa, spinal muscular atrophy and cerebellar degeneration; glomerulonephritis; myelodysplastic syndromes, ischemic injury associated with myocardial infarction, stroke and reperfusion injury, arrhythmia, atherosclerosis, toxin-induced or alcohol-related liver diseases, hematological diseases, eg, chronic anemia and aplastic anemia; degenerative diseases of the musculoskeletal system, for example, osteoporosis and arthritis, aspirin-sensitive rhinosinusitis, cystic fibrosis, multiple sclerosis, renal diseases and cancer pain.

It has also been found that certain cyclin-dependent kinase inhibitors may be used in combination with other anticancer agents. For example, the cyclin-dependent kinase inhibitor flavopiridol has been used with other anticancer agents in combination therapy.

Thus, in the pharmaceutical compositions, uses or methods of this invention for the treatment of a disease or condition comprising abnormal cell growth, the disease or condition comprising abnormal cell growth carrying out is in the form of a cancer.

A group of cancers include human breast cancers (e.g., primary breast tumors, breast cancer with lymph node-negative, invasive ductal adenocarcinomas of the breast, non-endometrioid breast cancers); and mantle cell lymphomas. In addition, other cancers are colorectal and endometrial cancers.

Another subset of cancers include breast cancer, ovarian cancer, colon cancer, prostate cancer, esophageal cancer, squamous cancer and non-small cell lung carcinomas. The activity of the compounds of the invention as inhibitors of cyclin-dependent kinases and glycogen synthase kinase-3 can be measured using the assays set forth in the examples below and the level of activity displayed for a given compound can be defined in terms of the IC50 value . Preferred compounds of the present invention are compounds having an IC value of only less than 1 micromole, more preferably less than 0.1 micromole. Methods for the Preparation of Compounds of the Invention

The compounds of formula (II) and the various subgroups thereof may be prepared according to methods of synthesis well known to the person skilled in the art. Unless otherwise indicated, R 1, R 2, R 3 and Y are as defined above. 102

In this section, as in all other sections of this application, references to formula (II) should also be taken to refer to formulas (IV), (IVa), (Va), (Vb), (Via) or (Vlb) and subgroups thereof, unless the context otherwise indicates.

The compounds of formula (II) may be prepared by reacting a carboxylic acid of the formula R 1 -CO 2 H or an activated derivative thereof with an appropriately substituted 4-amino-pyrazole as shown in Scheme 1.

The starting material for the synthetic route shown in Scheme 1 is 4-nitro-pyrazole-3-carboxylic acid (X) which can be obtained commercially or can be prepared by nitration of the corresponding unsubstituted carboxyl pyrazole compound in position 4. The 4-nitro-pyrazole carboxylic acid (X), or a reactive derivative thereof, is reacted with the amine H2 N-Y-R3 to give the 4-nitro-amide (XI). The coupling reaction between the carboxylic acid (X) and the amine is preferably carried out in the presence of a reagent of the type generally used in the formation of peptide bonds. Examples of such reagents include 1,3-dicyclohexylcarbodiimide (DCC) (Sheehan et al., J. Amer.Chem.Soc. 1955, 77, 1067), 1-ethyl-3- (3'-dimethylaminopropyl) carbodiimide referred to as EDC or EDAC but also known in the art as EDCI and WSCDI) (Sheehan et al, J. Org. Chem., 1961, 26, 2525), uronium-based coupling agents such as 0- (7-chlorohexafluorophosphate (HATU) and phosphonium-based coupling agents such as 1-benzo-triazolyloxytris (pyrrolidino) phosphonium hexafluorophosphate (PyBOP) (Castro et al. et al., Tetrahedron Letters, 1990, 31, 205). Carbodiimide-based coupling agents are advantageously used in association with 1-hydroxy-7-azabenzotriazole (HOAt) (LA Carpino, J. Amer. Chem. Soc., 1993, 115, 4397) or 1-hydroxybenzotriazole (HOBt) (Konig et al., Chem. Ber., 103, 708, 2024-2034). Preferred coupling reagents include EDC (EDAC) and DCC in association with HOAt or HOBt. The coupling reaction is typically performed in a non-protic, non-aqueous solvent such as acetonitrile, dioxane, dimethylsulfoxide, dichloromethane, dimethylformamide or N-methylpyrrolidine, or in an aqueous solvent optionally together with one or more miscible cosolvents. The reaction may be carried out at room temperature or, where the reactants are less reactive (for example in the case of electron-deficient anilines having electron withdrawing groups, such as the sulfonamide groups) at a suitably high temperature. The reaction may be carried out in the presence of a non-104 base, a tertiary amine such as an interferon, for example triethylamine or IV, diisopropylethylamine.

As an alternative, a reactive derivative of the carboxylic acid can be used, e.g. an acid anhydride or chloride. Reaction with a reactive derivative such as an anhydride is typically achieved by stirring the amine and the anhydride at room temperature in the presence of a base such as pyridine.

The amines of formula H2N-Y-R3 may be obtained from commercial sources or may be prepared by any of a large number of standard synthetic methods well known to those skilled in the art, see for example, Advanced Organic Chemistry of Jerry March, 4th Edition, John Wiley & Sons, 1992, and Organic Synthesis, Volumes 1-8, John Wiley, edited by Jeremiah P. Freeman (ISBN: 0-471-31192-8), 1995, and see also the methods described in the experimental section below. The nitro-pyrazole amide (XI) is reduced to give the corresponding 4-amino compound of formula (XII). The reduction may be carried out by standard methods such as catalytic hydrogenation, for example in the presence of palladium on charcoal in a polar solvent such as ethanol or dimethylformamide at room temperature. As an alternative, the reduction may be effected using a reducing agent such as tin (II) chloride in ethanol, typically with heating, for example at the reflux temperature of the solvent. The 4-amino-pyrazole compound (XII) is then reacted with a carboxylic acid of the formula R1-CO2H, or a reactive derivative thereof, using the methods and conditions described above for amide formation (XI) to give a compound of formula (II). 105

The carboxylic acids of the formula R 1 -CO 2 H may be obtained commercially or may be synthesized according to methods well known to the person skilled in the art, see, for example, Advanced Organic Chemistry and Organic Synthesis, details of which are given above.

In an alternative synthetic route, the compounds of formula (II) may be prepared by reacting a compound of formula (XIII) (wherein X represents R 1 (CO) NH) with a compound of the formula R 3 -Y-NH 2. The reaction can be carried out using the amide coupling conditions described above.

Once formed, a compound of formula (II) may be transformed into another compound of formula (II) using standard chemical procedures well known in the art. For examples of functional group interconversions see, for example, Fiesers' Reaqents for Orqanic Synthesis, Volumes 1-17, John Wiley, edited by Mary Fieser (ISBN: 0-471-58283-2) and Orqanic Synthesis, Volumes 1-8 , John Wiley, edited by Jeremiah P. Freeman (ISBN: 0-471-31192-8), 1995.

The starting materials for the synthetic routes shown in the Schemes above, e.g. pyrazoles of formula (X), may be obtained commercially or may be prepared by methods known to those skilled in the art. These can be obtained using known methods, e.g. ketones, such as in a process described in EP308020 (Merck), or the methods discussed by Schmidt in Helv. Chim. Acta., 1956, 39, 986-991 and Helv. Chim. Acta., 1958, 41, 306-309. Alternatively, these may be obtained by conversion of a commercially available pyrazole, for example those containing halogen, nitro, ester or amide functionalities, into pyrazoles containing the desired functionality by standard methods known to a person skilled in the art. For example, in 3-carboxy-4-nitropyrazole, the nitro group can be reduced to an amine by standard methods. The 4-nitro-pyrazole-3-carboxylic acid (XII) can be obtained commercially or can be prepared by nitration of the corresponding unsubstituted carboxyl pyrazole compound at the 4-position, and the halogen-containing pyrazoles can be used in coupling reactions with tin or palladium chemistry.

Protection Groups

In many of the reactions described above it may be necessary to protect one or more groups to prevent reaction occurring at an undesirable location of the molecule. Examples of protecting groups, and methods of protecting and deprotecting functional groups, can be found in Protective Groups in Organic Synthesis (T. Green and P. Wuts, 3rd Edition, John Wiley and Sons, 1999).

For example, a hydroxyl group may be protected as an ether (-OR) or an ester (-OC (= O) R), for example as: a t-butyl ether; a tetrahydropyranyl ether (THP); a benzyl ether, benzhydryl (diphenylmethyl) or trityl (triphenylmethyl); A trimethylsilyl or t-butyldimethylsilyl ether; or an acetyl ester (-OC (= O) CH 3, -OAc).

An aldehyde or ketone group may be protected, for example, as an acetal (R-CH (OH) 2) or ketal (R2C (OR) 2), respectively, in which the carbonyl group (> C = O) is converted in a diether (> C (OR) 2) by reaction with, for example, a primary alcohol. The aldehyde or ketone group is readily regenerated by hydrolysis using a large excess of water in the presence of acid.

An amine group may be protected, for example, as an amide (-NRCO-R) or a urethane (-NRCO-OR), for example, as: a methylamide (-NHCO-CH 3); a benzyloxylamide (-NHCO-OCH2 C6 H5, -NH-Cbz or NH-Z); as a t-butoxylamide (-NHCO-OC (CH 3) 3, -NH-Boc); a 2-biphenyl-2-propoxylamide (-NHCO-OC (CH 3) 2 C 6 H 4 C 6 H 5, -NH-Bpoc), as a 9-fluorenylmethoxylamide (-NH-Fmoc), as a 6-nitroveratryloxylamide (-NH- 2-trimethylsilylethyloxylamide (-NH-Teoc) as a 2,2,2-trichloroethyloxylamide (-NH-Troc), as an allyloxylamide (-NH-Alloc) or as a 2- (-phenylsulfonyl) ethyloxylamide (-NH-Psec) .

For example, in Scheme 1 above, when the R 3 moiety in the amine H 2 N-Y-R 3 contains a second amino group, such as a cyclic amino group (eg, a piperidine or pyrrolidine group), the second amino group can be protected by means of a protecting group as defined above, a preferred group being the tert-butyloxycarbonyl (Boc) group. Where subsequent modification of the second amino group is not required, the protecting group may be carried along the reaction sequence to give an N-protected form of a compound of formula (II), which may then be deprotected by standard methods (egr Acid treatment in the case of the Boc group) to give the compound of formula (II).

Other protecting groups for amines, such as cyclic amines and heterocyclic NH groups, include toluenesulfonyl (tosyl) and methanesulfonyl (mesyl) groups, benzyl groups such as para-methoxybenzyl (PMB) groups and tetrahydropyranyl (THP) .

A carboxylic acid group may be protected as an ester for example, such as: a C 1-7 alkyl ester (e.g., a methyl ester, a t-butyl ester); a C 1-7 haloalkyl ester (e.g., a tri-C 1-7 -haloalkyl ester); a tri-C 1-7 alkylsilyl-C 1-7 alkyl ester; or a C5-20 aryl C1-7 alkyl ester (e.g., a benzyl ester, a nitrobenzyl ester); or as an amide, for example as a methylamide. A thiol group may be protected, for example, as a thioether (-SR), for example as: a benzyl thioether; an acetamidomethyl ether (-S-CH 2 NHC (= O) CH 3).

Isolation and purification of the compounds of the invention

The compounds of the invention may be isolated and purified according to standard techniques well known to the person skilled in the art. One technique of particular utility in the purification of the compounds is preparative liquid chromatography using mass spectrometry as a means of detecting the purified compounds emerging from the chromatography column. Preparative LC-MS is a standard and efficient method used for the purification of small organic molecules, such as the compounds described herein. Methods for liquid chromatography (LC) and mass spectrometry (MS) may be modified to provide better separation of raw materials and improve MS detection of the samples. The optimization of the preparative gradient LC method will involve the modification of columns, eluents and volatile modifiers, and gradients. Methods for optimizing preparative LC-MS methods and for using them to purify compounds are well known in the art. Such methods are described in Rosentreter U, Huber U .; Optimal fraction collecting in preparative LC / MS; J Comb Chem .; 2004; 6 (2), 159-64 and Leister W, Strauss K, Wisnoski D, Zhao Z, Lindsley C., Development of a custom high throughput preparative liquid chromatography / mass spectrometer for the preparative purification and analytical analysis of compound libraries; J Comb Chem .; 2003; 5 (3); 322-9.

An example of such a system for purifying compounds via preparative LC-MS is described below in the Examples section of this application (under the heading " LC-MS System for Mass Co-ordinated Purification "). However, it will be understood that alternative systems and methods to those described could be used. In particular, standard phase preparative LC based methods may be used instead of the reverse phase methods described herein. Most preparative LC-MS systems utilize reverse phase LC and volatile acid modifiers, since the approach is very effective for purification of small molecules and because the eluents are compatible with positive ion electrospray mass spectrometry. The use of other chromatographic solutions, e.g. normal phase LC, alternatively buffered mobile phase, basic modifiers etc. as outlined in the analytical methods 110 described below could alternatively be used to purify the compounds.

Pharmaceutical formulations

Although the active compound may be administered alone, it is preferred to present it as a pharmaceutical composition (eg, formulation) comprising at least one active compound of the invention together with one or more carriers, adjuvants, excipients, diluents, fillers, buffers , stabilizers, preservatives, pharmaceutically acceptable lubricants, or other materials well known to those skilled in the art and, optionally, other therapeutic or prophylactic agents.

Thus, the present invention further provides pharmaceutical compositions as defined above, and methods of preparing a pharmaceutical composition comprising the combination of at least one active compound, as defined above, together with one or more carriers, excipients, buffers, adjuvants, stabilizers , or other pharmaceutically acceptable materials, as described herein. The term " pharmaceutically acceptable " as used herein refers to compounds, materials, compositions and / or dosage forms which are, within the scope of a sound medical opinion, suitable for use in contact with the tissues of an individual (eg, human) without toxicity, irritation, allergic response, or other problem or excessive complication, provided with a reasonable benefit / risk ratio. Each vehicle, excipient, etc. must also be " acceptable " in the sense of being compatible with the other ingredients of the formulation. 111

Accordingly, in a further aspect, the invention provides compounds of the formula (II) and its subgroups, such as formulas (IV), (IVa), (Va), (Vb), (Via) or (Vlb) and their subgroups as defined herein in the form of pharmaceutical compositions.

The pharmaceutical compositions may be in any form suitable for oral, parenteral, topical, intranasal, ophthalmic, optical, rectal, intravaginal or transdermal administration. When the compositions are intended for parenteral administration, they may be formulated for intravenous, intramuscular, intraperitoneal, subcutaneous or for direct administration to a target organ or tissue by injection, infusion or other means of administration.

In a preferred embodiment of the invention, the pharmaceutical composition is in a form suitable for i.v. administration, for example, by injection or infusion.

In another preferred embodiment, the pharmaceutical composition is in a form suitable for subcutaneous (s.c.) administration.

Suitable pharmaceutical dosage forms for oral administration include tablets, capsules, oval tablets, pills, lozenges, syrups, solutions, powders, granules, elixirs and suspensions, sublingual tablets, wafers or adhesives and mouthpieces.

Pharmaceutical compositions containing compounds of formula (II) may be formulated according to known techniques, see for example, Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, PA, USA.

Thus, the tablet compositions may contain a unit dosage of active compound together with an inert diluent or carrier, such as a sugar or sugar alcohol, e.g. g .; lactose, sucrose, sorbitol or mannitol; and / or a non-sugar diluent, such as sodium carbonate, calcium phosphate, calcium carbonate, or a cellulose or derivative thereof, such as methylcellulose, ethylcellulose, hydroxypropylmethylcellulose, and starches such as corn starch. The tablets may also contain standard ingredients, such as binders and granulating agents, such as polyvinylpyrrolidone, disintegrants (eg, expandable crosslinked polymers, such as crosslinked carboxymethylcellulose), lubricants (eg, stearates), preservatives (eg, parabens), antioxidants ( eg, BHT), buffering agents (for example, phosphate or citrate buffers), and effervescent agents, such as citrate / bicarbonate mixtures. Such excipients are well known and need not be discussed here in detail.

The capsule formulations may be of the hard gelatin variety or soft gelatin and may contain the active component in the solid, semi-solid or liquid form. Gelatin capsules may be prepared from animal gelatin or their equivalents of synthetic or vegetable origin.

Solid dosage forms (eg, tablets, capsules, etc.) may be coated or uncoated, but typically have a coating, for example a film-protecting coating (eg, a wax or varnish) or a release coating controlled. The coating (e.g., an Eudragit ™ type polymer) may be designed to release the active component at a desired location within the gastrointestinal tract. Thus, the coating may be selected so as to degrade under certain pH conditions in the gastrointestinal tract, thereby selectively releasing the compound in the stomach or the ileum or duodenum.

In place of or in addition to a coating, the drug may be presented in a solid matrix comprising a release-controlling agent, for example a release-delay agent which may be adapted to selectively release the compound under varying acidity or alkalinity conditions in the gastrointestinal tract. Alternatively, the matrix material or release delay coating may take the form of an erodible polymer (e.g., a maleic anhydride polymer) which is substantially continuously eroded as the dosage form passes through the gastrointestinal tract. As a further alternative, the active compound may be formulated into an administration system which provides osmotic control of the release of the compound. Osmotic release and other sustained release or sustained release formulations may be prepared according to methods well known to those skilled in the art.

Compositions for topical use include ointments, creams, spray formulations, adhesives, gels, liquid droplets and implants (for example, intraocular implants). Such compositions may be formulated according to known methods. 114

Compositions for parenteral administration are typically presented as aqueous or oily solutions or sterile suspensions, or may be provided in the form of finely divided sterile powder for extemporaneous preparation with sterile water for injection.

Examples of formulations for rectal or intravaginal administration include pessaries and suppositories which may be, for example, prepared from a moldable or waxed profile material containing the active compound.

Compositions for administration by inhalation may take the form of inhalable powder compositions or formulations for spraying liquid or powder, and may be administered in a standard manner using powder inhaler devices or aerosol dispensing devices. Such devices are well known. For administration by inhalation, the powdered formulations typically comprise the active compound together with a solid inert powder diluent such as lactose.

Compounds of the inventions will generally be presented in unit dosage form and, as such, will typically contain sufficient compound to provide a desired level of biological activity. For example, a formulation intended for oral administration may contain from 0.1 milligrams to 2 grams of active ingredient, more generally from 10 milligrams to 1 grams, for example, 50 milligrams to 500 milligrams. The active compound will be administered to a patient in need thereof (e.g., a human or a diseased animal) in an amount sufficient to achieve the desired therapeutic effect. 115 Treatment Methods

Compounds of formula (II) and subgroups thereof, such as formulas (IV), (IVa), (Va) or (VIb) and their subgroups as defined herein, are considered to be useful in the prophylaxis or treatment of a range of conditions or pathological conditions mediated by cyclin-dependent kinases. Examples of such conditions and conditions are indicated above.

The compounds are generally administered to a subject in need of such administration, for example, a human or diseased animal, preferably a human.

The compounds will typically be administered in amounts that are therapeutically or prophylactically useful and are generally non-toxic. However, in certain situations (e.g. in the case of potentially fatal diseases), the benefits of administering a compound of formula (II) may overcome the disadvantages of any toxic effects or side effects, in which case it may be considered desirable to administer the compounds in amounts that are associated with a degree of toxicity.

The compounds may be administered over an extended period to maintain beneficial therapeutic effects or may be administered only for a short time. Alternatively, they may be administered in a pulsatile or continuous manner.

A typical daily dose of the compound may be in the range of from 100 picogram to 100 milligrams per kilogram of body weight, more typically 5 nanogram to 25 milligrams per kilogram of 116 body weight, and more generally 10 nanogram to 15 milligrams per kilogram (eg 10 nanogram at 10 milligram) per kilogram of body weight, although larger or smaller doses may be given when necessary. Ultimately, the amount of compound administered and the type of composition used will be appropriate to the nature of the disease or physiological condition to be treated and will be at the discretion of the physician.

The compounds of formula (II) may be administered as the sole therapeutic agent or they may be administered in combination therapy with one or more other compounds for treatment of a particular disease state, for example, a neoplastic disease such as a cancer as defined above. Examples of other therapeutic agents which may be administered together (simultaneously or at different time intervals) with the compounds of the formula (II) include but are not limited to topoisomerase inhibitors, alkylating agents, antimetabolites, DNA binders and microtubule inhibitors (tubulin targeting agents), such as cisplatin, cyclophosphamide, doxorubicin, irinotecan, fludarabine, 5FU, taxanes, mitomycin C or radiotherapy. Alternatively, the compounds of formula (II) may be administered in combination therapy with monoclonal antibodies or signal transduction inhibitors. For the case of CDK inhibitors combined with other therapies, the two or more treatments may be administered in dosing regimens that vary individually and through different pathways.

When the compound of formula (II) is administered in combination therapy with one, two, three, four or more other therapeutic agents (preferably one or two, more preferably one), the compounds may be administered simultaneously or sequentially. When administered sequentially, they may be administered at sparsely spaced intervals (for example, over a period of 5-10 minutes) or at longer intervals (for example, 1, 2, 3, 4 or more hours apart, or at even further intervals when necessary), the exact dosing regimen being adapted to the properties of the therapeutic agent (s).

The compounds of the invention may also be administered in conjunction with non-chemotherapeutic treatments, such as radiotherapy, photodynamic therapy, gene therapy; surgery and controlled diets.

For use in combination therapy with another chemotherapeutic agent, the compound of formula (II) and one, two, three, four or more other therapeutic agents may be, for example, formulated together in a dosage form containing two, three, four or more therapeutic agents. In one alternative, the individual therapeutic agents may be formulated separately and presented together in the form of a kit, optionally with instructions for their use.

One skilled in the art knows, through his / her common general knowledge, which dosing regimens and combination therapies to use. Diagnostic Methods

Prior to administration of a compound of formula (II), a patient may be screened to determine whether a disease or condition of which the patient suffers or may suffer is one that would be amenable to treatment with a compound having activity against cyclin-dependent kinases .

For example, a biological sample harvested from a patient may be analyzed to determine whether a condition or disease, such as cancer, that the patient suffers from or may suffer from is one that is characterized by a genetic abnormality or abnormal protein expression leading to overactivation of CDK or the sensitization of a pathway to normal CDK activity. Examples of such abnormalities that result in activation or sensitization of the CDK2 signal include the positive regulation of cyclin E, (Harwell RM, Mull BB, Porter DC, Keyomarsi K, J Biol Chem, 2004 Mar 26; 126 95-705) or the loss of p21 or p27, or the presence of CDC4 variants (Rajagopalan H, Jallepalli PV, Rago C, Velculescu VE, Kinzler KW, Vogelestein B, Lengauer C, Nature 2004 Mar 4; (6978): 77-81). The term " positive regulation " includes elevated expression or overexpression, including gene amplification (i.e., multiple gene copies) and expression enhanced by a transcriptional effect, and hyperactivity and activation, including mutation activation. Thus, the patient may undergo a diagnostic test to detect a characteristic marker for the positive regulation of cyclin E, or loss of p21 or p27, or the presence of CDC4 variants. The term diagnosis includes screening. By labeling the applicants include genetic markers including, for example, measuring DNA composition to identify CDC4 mutations. The term "marker" also includes labels that are characteristic of the positive regulation of cyclin E, including enzyme activity, enzyme levels, enzyme status (e.g., phosphorylated or not) and mRNA levels of the above-mentioned proteins. 119

Tumors with a positive regulation of cyclin E, or loss of p21 or p27 may be particularly sensitive to CDK inhibitors. Preferably, tumors can be screened for positive regulation of cyclin E, or loss of p21 or p27 prior to treatment. Thus, the patient may undergo a diagnostic test to detect a marker characteristic of the positive regulation of cyclin E, or loss of p21 or p27. Diagnostic tests are typically performed on a selected biological sample of tumor biopsy samples, blood samples (isolation and enrichment of deposited tumor cells), fecal biopsies, sputum, chromosome analysis, pleural fluid, peritoneal fluid, or urine.

It has been found, Rajagopalan et al. (Nature 2004 Mar 4; 428 (6978): 77-81), that there were mutations present in CDC4 (also known as Fbw7 or Archipelado) in human endometrial colorectal cancers and endometrial cancers (Spruck et al., Cancer Res. 2002 Aug 15, 62 (16): 4535-9). Identification of individuals having a mutation in CDC4 may mean that the patient would be particularly suitable for treatment with a CDK inhibitor. Preferably, tumors can be screened for the presence of a CDC4 variant prior to treatment. The screening process will typically involve forward sequencing, oligonucleotide microarray analysis, or a mutant specific antibody.

Methods of identifying and analyzing mutations and regulating proteins are known to a person skilled in the art. Screening methods could include, but are not limited to, standard methods, such as polymerase chain reaction (RT-PCR) reverse transcriptase or in situ hybridization. 120

In RT-PCR screening, the level of mRNA in the tumor is assessed by creating a cDNA copy of the mRNA followed by amplification of the cDNA by PCR. Methods of PCR amplification, primer selection and amplification conditions are known to a person skilled in the art. Nucleic acid manipulations and PCR are performed by standard methods, as described for example in Ausubel, F. M. et al., Eds. Current Protocols in

Molecular Biology, 2004, John Wiley & Sons Inc., or Innis, M.A. et al., Eds. PCR Protocols: A Guide to Methods and Applications, 1990, Academic Press, San Diego. Reactions and manipulations involving nucleic acid techniques are also described in Sambrook et al., 2001, 3rd Ed, Molecular Cloning: A Laboratory

Manual, Cold Spring Harbor Laboratory Press. Alternatively a commercially available kit for RT-PCR (for example, Roche Molecular Biochemicals) or methodology as set forth in U.S. Patents 4,666,828; 4,683,202; 4801531; 5192659, 5272057, 5882864, and 6218529.

An example of an in situ hybridization technique for evaluating mRNA expression would be in situ fluorescence hybridization (FISH) (see Angerer, 1987 Meth. Enzymol., 152: 649).

Generally, in situ hybridization comprises the following major steps: (1) fixation of the tissue to be analyzed; (2) pretreating the sample to increase the accessibility of the target nucleic acid and to reduce non-specific binding; (3) hybridizing the nucleic acid mixture with the nucleic acid in the biological framework or tissue; (4) post-hybridization washes to remove the unbound nucleic acid fragments in the hybridization, and (5) detection of the hybridized nucleic acid fragments. Probes used in such applications are typically labeled, for example, radioisotopes or fluorescent reporters. Preferred probes are sufficiently long, for example, from about 50, 100 or 200 nucleotides to about 1000 or more nucleotides, to allow specific hybridization with the target nucleic acid (s) under strident conditions. Current methods for performing FISH are described in Ausubel, F. M. et al., Eds. Current Protocols in Molecular Biology, 2004, John Wiley & Sons Inc and Fluorescence In Situ Hybridization: Technical OverView by John M. S. Bartlett in Molecular Diagnosis of Cancer, Methods and Protocols, 2nd ed .; ISBN: 1-59259-760-2; March 2004, p. 077-088; Series: Methods in Molecular Medicine.

Alternatively, the protein products expressed from the mRNAs can be analyzed by immunohistochemistry of tumor samples, solid phase immunoassay with microtiter plates, Western blotting, 2-dimensional SDS polyacrylamide gel electrophoresis, ELISA, flow cytometry and others methods known in the art for the detection of specific proteins. Methods of detection would include the use of site-specific antibodies. The skilled person will recognize that all of these well known techniques for detecting positive regulation of cyclin E, or loss of p21 or p27, or detection of CDC4 variants could be applicable in the present case.

Therefore, all of these techniques could also be used to identify tumors particularly suitable for treatment with CDK inhibitors. Patients with mantle cell lymphoma (MCL) could be selected for treatment with a CDK inhibitor using the diagnostic tests outlined herein. MCL is a clinicopathological entity distinct from non-Hodgkin's lymphoma, characterized by proliferation of small to medium lymphocytes with co-expression of CD5 and CD20, an aggressive and incurable clinical course, and t (11; 14) translocation ( ql3; q32) frequent. Overexpression of cyclin D1 mRNA found in mantle cell lymphoma (MCL) is a critical diagnostic marker. Yatabe et al. (Blood, 2000 Apr 1; 95 (7): 2253-61) proposed that positivity to cyclin D1 should be included as one of the standard criteria for MCL and that innovative therapies should be explored for this incurable disease based on the new criteria. Jones et al. (J Mol Diagn. 2004 May; 6 (2): 84-9) developed a quantitative, real-time reverse transcription PCR assay for the expression of cyclin D1 (CCND1) to aid in the diagnosis of mantle cell lymphoma (MCL). Howe et al. (Clin Chem 2004 Jan; 50 (1): 80-7) used real-time quantitative RT-PCR to evaluate the expression of cyclin D1 mRNA and determined that quantitative RT-PCR for cyclin D1 mRNA normalized to CD19 mRNA can be used in the diagnosis of MCL in blood, marrow and tissue. Alternatively, breast cancer patients could be selected for treatment with a CDK inhibitor using the diagnostic tests outlined above. Tumor cells generally overexpress cyclin E and cyclin E has been shown to be overexpressed in breast cancer (Harwell et al., Cancer Res, 2000, 60, 481-489). Therefore, breast cancer may in particular be treated with a CDK inhibitor. 123

Antifungal use

In another aspect, the invention provides the use of the compounds of the formulas (II), (IV), (IVa), (Va), (Vb), (Way) or (VIb) and their subgroups, as defined herein, as agents antifungals.

The compounds may be used in animal medicine (for example, in the treatment of mammals, such as humans), or in the treatment of plants (e.g., in agriculture and horticulture), or as general antifungal agents, for example as preservatives and disinfectants.

In one embodiment, the invention provides a compound of formula (II) and its subgroups, such as formulas (IV), (IVa), (Va), (Vb), (Way) or (VIb) and their subgroups as herein defined for use in the prophylaxis or treatment of a fungal infection in a mammal such as a human. Also provided is the use of a compound of formula (II) and its subgroups, such as formulas (IV), (IVa), (Va), (Vb), (Way) or (VIb) and their subgroups as defined herein for the manufacture of a medicament for use in the prophylaxis or treatment of a fungal infection in a mammal such as a human.

For example, the compounds of the invention may be administered to human patients suffering or at risk of infection by topical fungal infections caused by, among other organisms, Candida species, Trichophyton,

Microsporum or Epidermophyton, or in mucosal infections 124 caused by Candida albicans (e.g., vaginal thrush and candidiasis). The compounds of the invention may also be administered for the treatment or prophylaxis of systemic fungal infections caused, for example, by Candida albicans, Cryptococcus neoformans, Aspergillus flavus, Aspergillus fumigatus, Coccidioidies, Paracoccidioides, Histoplasma or Blastomyces.

In another aspect, the invention provides an antifungal composition for agricultural (including horticultural) use, comprising a compound of the formula (II) and its subgroups, such as of formulas (IV), (V) and (VI) as defined above together with an agriculturally acceptable diluent or carrier. The invention further provides a method of treating an animal (including a mammal such as a human), plant or seed having a fungal infection, which comprises treating said animal, plant or seed, or the location of said plant or seed, with an effective amount of a compound of the formula (II) and its subgroups, such as of formulas (IV), (V) and (VI) as defined above. The invention also provides a method of treating a fungal infection in a plant or seed, which comprises treating the plant or seed with an antifungal effective amount of a fungicidal composition as defined above.

Differential selection assays may be used to select the compounds of the present invention with specificity for non-human CDK enzymes. Compounds that specifically act on the CDK enzymes of eukaryotic pathogens may be used as antifungal or antiparasitic agents. Candida CDK kinase inhibitors, CKSI, may be used in the treatment of candidiasis. Antifungal agents may be used against infections of the above-defined type, or opportunistic infections which usually occur in debilitated and immunosuppressed patients, such as patients with leukemias and lymphomas, persons receiving immunosuppressive therapy, and patients with predisposing conditions such as diabetes mellitus or AIDS , as well as for non-immunosuppressed patients.

Assays described in the art may be used to screen for agents that may be useful for inhibiting at least one fungus implicated in mycoses, such as candidiasis, aspergillosis, mucormycosis, blastomycosis, geotrichosis, cryptococcosis, chromoblastomycosis, coccidioidomycosis, conidiosporosis, histoplasmosis, maduromycosis, rhinosporidiosis , nocardiosis, para-actinomycosis, penicilliosis, monoliase or sporotrichosis. Differential screening assays may be used to identify antifungal agents that may be of therapeutic value in the treatment of aspergillosis using CDK genes cloned from yeast such as Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Aspergillus nidulans or Aspergillus terreus, or the fungal infection is mucormycosis, the CDK assay may be derived from yeast, such as Rhizopus arrhizus, Rhizopus oryzae, Absidia corymbifera, Absidia ramosa or Mucorpusillus. Sources of other CDK enzymes include the pathogen Pneumocystis carinii. By way of example, the in vitro evaluation of the antifungal activity of the compounds may be carried out by determining the minimum inhibitory concentration (M.I.C.) which is the concentration of the test compounds in a suitable medium at which growth of the particular microorganism ceases to occur. In practice, a series of agar plates each having the test compound incorporated at a particular concentration is inoculated with a standard culture of, for example, Candida albicans and each plate is then incubated for a suitable period at 37Â ° W. The plates are then examined for the presence or absence of growth of the fungus and the value M.I.C. appropriate. Evaluation of the compounds in vivo can be performed at a series of dose levels by intraperitoneal or intravenous injection or by oral administration to mice that have been inoculated with a fungus e.g. a strain of Candida albicans or Aspergillus flavus. The activity of the compounds can be assessed based on the survival of a group of treated mice after the death of an untreated group of mice. The activity can be measured in terms of the dose level at which the compound provides 50% protection against the lethal effect of the infection (PD50).

For human antifungal use, the compounds may be administered alone or in combination with a pharmaceutical carrier selected according to the intended route of administration and standard pharmaceutical practice. Thus, for example, they may be administered orally, parenterally, intravenously, intramuscularly or subcutaneously via the formulations described above in the section entitled " Pharmaceutical Formulations ".

For oral and parenteral administration in human patients, the daily dosage level of the antifungal compounds of the invention may be from 0.01 to 10 mg / kg (in divided doses), depending, inter alia, on the potency of the compounds when administered by route oral or parenteral administration. The tablets or capsules of the compounds may contain, for example, from 5 mg to 0.5 g of active compound for single administration or two or more at the same time, as appropriate. In any case, the physician will determine the effective dosage (effective amount) which will be most suitable for a particular patient and will vary with the particular patient's age, weight and response.

Alternatively, the antifungal compounds may be administered in the form of a suppository or pessary, or they may be applied topically in the form of a lotion, solution, cream, ointment or powder for sprinkling. For example, they may be incorporated into a cream consisting of an aqueous emulsion of polyethylene glycols or liquid paraffin; or they may be incorporated at a concentration of 1 to 10% in an ointment consisting of a white wax or white soft paraffin base together with stabilizers and preservatives as may be required.

In addition to the therapeutic uses described above, the antifungal agents developed with the differential selection assays may be used, for example, as preservatives in foodstuffs, food supplements to promote weight gain in livestock, or in disinfectant formulations for the treatment of non- alive, and. for decontamination of equipment and hospital rooms. Similarly, side-by-side comparison of inhibition of a mammalian CDK and an insect CDK, such as the Drosophilia CDK5 gene (Hellmich et al. (1994) FEBS Lett 356: 317-21), will allow selection between the compounds herein of inhibitors which discriminate between the human / mammalian and insect enzymes. Accordingly, the present invention expressly contemplates the use and formulations of the compounds of the invention in insecticides, such as for use in controlling insects such as the fruit fly.

In yet another embodiment, certain of the subject CDK inhibitors may be selected based on the specificity of inhibition to plant CDK relative to the mammalian enzyme. For example, a plant CDK can be arranged in a differential screening with one or more of the human enzymes to select those compounds with greater selectivity to inhibit the plant enzyme. Thus, the present invention specifically contemplates formulations of CDK inhibitors subject to agricultural applications, such as in the form of a defoliant or the like.

For agricultural and horticultural purposes, the compounds of the invention may be used in the form of a composition formulated as appropriate for the particular intended use and intended purpose. Thus, the compounds may be applied in the form of powders for sprinkling, or granulates, seed treatments, aqueous solutions, dispersions or emulsions, immersion formulations, spray formulations, aerosols or vapors. The compositions may also be provided in the form of dispersible powders, granules or grains, or concentrates for dilution prior to use. Such compositions may contain conventional carriers, diluents or adjuvants as are known and acceptable in agriculture and horticulture, and are manufactured according to the conventional Processes. The compositions may also incorporate other active ingredients, for example, compounds having herbicidal or insecticidal activity or another fungicide. The compounds and compositions may be applied in a number of ways, for example, these may be applied directly to the plant foliage, stems, branches, seeds or roots or to soil or other growth medium, and these may be used not only for eradicate the disease, but also prophylactically to protect the plants or seeds from the snake. By way of example, the compositions may contain from 0.01 to 1% by weight of active ingredient. For field use, the likely application rates of the active ingredient may be from 50 to 5000 g / hectare. The invention also contemplates the use of the compounds of formula (II) and its subgroups, such as formulas (IV), (IVa), (Va), (Vb), (Way) or (VIb) and their subgroups as defined in the control of fungi from decomposition of wood and in the treatment of cultivated soils, transplant paddies or water for infusion. Also contemplated by the invention is the use of the compounds of the formula (II) and its subgroups, such as formulas (IV), (IVa), (Va), (Vb), (Way) or (VIb) and their subgroups as here defined to protect stored grains and other non-plant sites from fungal infestation.

The suspension is then centrifuged and washed twice with 0.85% NaCl before sonicating the washed cell suspension for 4 seconds (Branson Sonicator, model 350, Danbury, Conn.). The singlet blastospores are counted on a hemocytometer and adjusted to the desired concentration in 0.85% NaCl. The activity of the test compounds is determined using a modification of a broth microdilution technique. Test compounds are diluted in DMSO to a rate of 1.0 mg / mL, then diluted to 64 pg / mL in YNB broth, pH 7.0 with MOPS (Fluconazole is used as a control) to provide a working solution of each compound. Using a 96-well plate, wells 1 and 3 to 12 are made with YNB broth, ten-fold dilutions of the compound solution are made in wells 2 to 11 (the concentration ranges are 64 to 0.125 pg / ml). Well 1 is used as a sterility control and blank for spectrophotometric assays. Well 12 is used as a growth control. Microtiter plates are inoculated into each of wells 2 to 11 with 10 μl (final inoculum size is 104 organisms / ml). The inoculated plates are incubated for 48 hours at 35 ° C. MIC values are determined spectrophotometrically by measuring the absorbance at 420 nm (Automatic Microplate Reader, DuPont Instruments, Wilmington, Del.) After shaking the plates for 2 minutes with a vortex mixer (Vorte-Genie 2 Mixer, Scientific Industries, Inc. , Bolemia, NI). The MIC criterion is defined as the lowest concentration of drug which exhibits approximately 50% (or more) growth reduction compared to the control well. With the turbidity assay, this is defined as the lowest concentration of drug at which the turbidity in the well is <50% of the control (IC 50). The Concentrations 265

Minimal Citolytic (MCC) are determined by subcultured all wells of the 96-well plate in a Sabourahd Dextrose Agar (SDA) plate, incubating for 1 to 2 days at 35øC and then verifying the viability. EXAMPLE 254

Protocol for the Biological Evaluation of Control of Fungal Infection in Whole Plants in vivo

The compounds of formula (II) are dissolved in acetone, with subsequent successive dilutions in acetone to obtain a desired concentration range. Final volumes of treatment are obtained by adding 9 volumes of 0.05% aqueous Tween-20 ™ or 0.01% Triton X-100 ™ depending on the pathogen.

The compositions are then used to test the activity of the compounds of the invention against tomato mildew (Phytophthora infestans) using the following protocol. Tomatoes (Rutgers cultivar) are grown from the seed in a groundless peat pot mix until the shoots are 10-20 cm high. The plants are then sprayed to the test compound at a dilution of 100 ppm. After 24 hours, the test plants are inoculated by spraying with an aqueous suspension of Phytoftora infestans sporangia, and kept in a dew chamber overnight. The plants are then transferred to the greenhouse until disease develops in untreated control plants.

Similar protocols are also used to test the activity of the compounds of the invention to combat Rust 266
