Description

<div class="application article clearfix" id="description"> <p class="printTableText" lang="en">New Zealand Paient Spedficaiion for Paient Number 523656 <br><br> 523656 <br><br> WO 02/18346 PCT/IBO1/01540 <br><br> PYRAZOLE DERIVATIVES AND THEIR USE AS PROTEIN KINASE INHIBITORS <br><br> Field of the Invention <br><br> The subject invention relates to pyrazole derivatives, pharmaceutical compositions 5 comprising such derivatives and methods of using such derivatives to treat abnormal cell growth and certain diseases and conditions of the central nervous system. The compounds of the present invention act as inhibitors of cyclin-dependent protein kinase enzymes cdk5 (cyclin-dependsnt protein kinase 5) and cdk2 (cyclin-dependent protein kinase 2). The compounds of the present invention also are inhibitors of the enzyme GSK-3 (glygocen 10 synthase kinase-3) enzyme. <br><br> Background of the Invention <br><br> The serine/threonine kinase cdk5 along with its cofactor p25 (or the longer cofactor, p35) has been linked to neurodegenerative disorders, and inhibitors of cdk5/p25 (or cdk5/p35) are therefore useful for the treatment of neurodegenerative disorders such as Alzheimer's 15 disease, Parkinson's disease, stroke, or Huntington's disease. Treatment of such neurodegenerative disorders using cdk5 inhibitors is supported by the finding that cdk5 is involved in the phosphorylation of tau protein (J. Biochem, 117, 741-749 (1995)). cdk5 also phosphorylates Dopamine and Cyclic AMP-Regulated Phosphorprotein (DARPP-32) at threonine 75 and is thus indicated in having a role in dopaminergic neurotransmission 20 (Nature, 402, 669-671 (1999)). <br><br> The serine/threonine kinase cdk2 is essential for normal ceil cycling and plays a critical roie in disorders arising from abnormal cell cycling, a common characteristic of many - oncological disorders. Inhibitors of cdk2 are therefore useful for the treatment of various types of cancer and other diseases or conditions related to abnormal cell growth (Meijer, et ai., 25 Properties and Potentiai-applications of Chemical Inhibitors of Cyclin-dependent Kinsases, Pharmacology &amp; therapeutics, 82 (2-3), 279-284 (1999); Sausviile, et al., Cyclin-dependent Kinases: initial Approaches to Exploit a Novel Therapeutic Target, Pharmacology &amp; therapeutics 82 (2-3) 285-292 (1999)). <br><br> GSK-3 is a serine/threonine protein kinase. It is one of several protein kinases which 30 phosphorylate glycogen synthase (Embi, et al., Eur. J. Biochem. 107:519-527 (1980); Hemmings, etal., Eur. J. Biochem. 119:443-451 (1982)). GSK-3 exists in two isoforms, a and P, in vertebrates, reported as having a monomeric structure of 49kD and 47kD respectively. Both isoforms phosphorylate muscle glycogen synthase (Cross, et al., Biochemical Journal 303: 21-26 (1994)). The amino acid identity among GSK-3 species homologs has been 35 indicated to be in excess of 98% within the catalytic domain (Plyte, et al., Biochim. Biophys. <br><br> -2' <br><br> Acta 1114:147-162) (1992)). Due to a remarkably high degree of conservation across the phyiogenetic spectrum, a fundamental role of GSK-3 in cellular processes is suggested. <br><br> GSK-3 has been implicated in numerous different disease states and conditions. For example, Chen, et al, Diabetes 43: 1234-1241 (1994) have suggested that an increase in 5 GSK-3 activity can be important in Type 2 diabetes, increased GSK-3 expression in diabetic muscle is also though to contribute to the impaired glycogen synthase activity and skeletal muscle insulin resistance present in Type 2 diabetes (Nikoulina, et al., Diabetes 49: 263-271 (2000)). Also, a higher activity of a type 1 protein phosphatase measured in immotile sperm was attributed to higher GSK-3 activity and was indicated as responsible for holding the 10 sperm motility in check (Vijayaraghavan, et al. Biology of Reproduction 54: 709-718 (1996)). Vijayaraghavan et al. indicate that such results suggest a biochemical basis for the development and regulation of sperm motility and a possible physiological role for a protein phosphatase 1/inhibitor 2/GSK-3 system. GSK-3 activity has also been associated with Alzheimer's disease and mood disorders such as bipolar disorder (WO 97/41854). Among 15 other conditions, GSK-3 has furthermore been implicated in hair loss, schizophrenia, and neurodegeneration, including both chronic neurodegenerative diseases (such as Alzheimer's, supra) and neurotrauma, for example stroke, traumatic brain injury, and spinal cord trauma. <br><br> wherein R1 is a straight chain or branched (C1-C8)aikyl, a straight chain or branched (C2-C8)alkenyl, a straight chain or branched (C2-CB)alkynyl, (C4-Ca)cycloalkenyl, (3-25 8 membered) heterocycloalkyl, (Cs-C^bicycloalkyl, (Cr-C^bicycloalkenyl, or (5-11 membered) heterobicycloalkyl;

The formulations and routes of administration for such therapies and 15 compositions can be based on the information described herein for compositions and therapies comprising a compound of the invention as the sole active agent and on information provided for the other agent in combination therewith. <br><br> A specific compound of formula 1 can be determined to inhibit cdk2, cdk5, or GSK-3 using biological assays known to those of ordinary skill in the art, for example the assays 20 described below. <br><br> The specific activity of a compound of formula 1 for inhibition of cdk5 or cdk2 can, for example, be ascertained by means of the following assays using materials available to those of ordinary skill in the art: <br><br> Enzyme activities can be assayed as the incorporation of [33P] from the gamma 25 phosphate of [33P]ATP (Amersham, cat. no. AH-9968) into biotinylated peptide substrate PKTPKKAKKL. In such an assay, reactions are carried out in a buffer containing 50mM Tris-HCl, pH 8.0; 10mM MgCI2, 0.1mM Na3V04, and 1mM DTT. The final concentration of ATP is about 0.5uM (final specific radioactivity of 4uCi/nmol), and the final concentration of substrate 0.75uM. Reactions, initiated by the addition of either cdk5 and activator protein p25 or cdk2 30 and activator cyclin E, may be carried out at room temperature for about 60 minutes. Reactions are stopped by addition of 0.6 volume of buffer containing (final concentrations): 2.5mM EDTA, 0.05%Triton-X 100, 100uM ATP, and 1.25 mg/ml streptavidin coated SPA beads (Amersham cat. no. RPNQ0007). Radioactivity associated with the beads is quantified by scintillation counting. <br><br> 35 The specific activity of a compound of formula 1 for inhibition of GSK-3 can be determined in both cell-fee and cell-based assays, both of which are described in the art (see, <br><br> WO 02/18346 <br><br> PCT/IB01/01540 <br><br> -55- <br><br> for example, WO 99/65897). A cell-free assay can be carried out in general by incubating GSK-3 with a peptide substrate, radiolabeled ATP (such as, for example, y^P- or y^-P-ATP, both available from Amersham, Arlington Heights, Illinois), magnesium ions, and the compound to be assayed. The mixture is incubated for a period of time to allow incorporation 5 of radiolabeld phosphate into the peptide substrate by GSK-3 activity. The reaction mixture is washed to remove unreacted radiolabeled ATP, typically after first transferring all or a portion of the enzyme reaction mixture to a well that contains a uniform amount of a ligand that is capable of binding to the peptide substrate. The amount of 33P or 32P remaining in each well after washing is then quantified to determine the amount of radiolabeled phosphate 10 incorporated into the peptide substrate. Inhibition is observed as a reduction, relative to a control, in the incorporation of radiolabeled phosphate into the peptide substrate. An example of a suitable GSK-3 peptide substrate for an assay is the SGSG-linked CREB peptide sequence, derived from the CREB DNA binding protein, described in Wang, et al., Anal. Biochem., 220:397-402 (1994). Purified GSK-3 for an assay may, for example, be obtained 15 from cells transfected with a human GSK-3P expression plasmid as described in, for example Stambolic, et al., Current Biology 6:1664-68 (1996). WO 99/65897; Wang, et al., and Stambolic, et al. are incorporated in their entireties herein by reference. <br><br> Another example of a GSK-3 assay, similar to the one described in the preceding paragraph is as follows: Enzyme activities are assayed as the incorporation of [33P] from 20 gamma phosphate of [33P]ATP (Amersham, cat. No. AH-9968) into biotinylated peptide substrate PKTPKKAKKL. Reactions are carried out in a buffer containing 50mM Tris-HCI, pH 8.0; 10mM MgCl2, 0.1mM Na3V04, and 1mM DTT. The final concentration of ATP is O.SuM (final specific radioactivity of 4(iCi/nmoI), and the final concentration of substrate is 0.75^M. Reactions, initiated by the addition of enzyme, are carried out at room temperature for about 25 60 minutes. Reactions are stopped by addition of 0.6 volume of buffer containing (final concentrations): 2.5mM EDTA, 0.05%Triton-X 100, 100fiM ATP, and 1.25 mg/ml streptavidin coated SPA beads (Amersham cat. No. RPNQ0007). Radioactivity associated with the beads is quantified by scintillation counting. <br><br> All of the title compounds of the following Examples had an ICS0 inhibiting peptide 30 substrate phosphorylation of less than about 50 )iM when assayed for cdk5 inhibition according to the preceding assay. <br><br> Several of the title compounds of the following Examples were assayed for GSK-3 inhibition using an assay such as that described above, and all tested had an IC^, for inhibition of GSK-3P of less than about 50 |iM . <br><br> WO 02/18346 <br><br> PCT/IB01/01540 <br><br> -56- <br><br> The following Examples illustrate the present invention.
