Description
WO 97/36591 PCT/US97/04750 -1- TITLE OF THE INVENTION INHIBITORS OF FARNESYL-PROTEIN TRANSFERASE 4, BACKGROUND OF THE INVENTION The Ras proteins (Ha-Ras, Ki4a-Ras, Ki4b-Ras and N-Ras) are part of a signalling pathway that links cell surface growth factor receptors to nuclear signals initiating cellular proliferation. Biological and biochemical studies of Ras action indicate that Ras functions like a G-regulatory protein. In the inactive state, Ras is bound to GDP. Upon growth factor receptor activation Ras is induced to exchange GDP for GTP and undergoes a conformational change. The GTP-bound form of Ras propagates the growth stimulatory signal until the signal is terminated by the intrinsic GTPase activity of Ras, which returns the protein to its inactive GDP bound form Lowy and D.M.
Willumsen, Ann. Rev. Biochem. 62:851-891 (1993)). Mutated ras genes (Ha-ras, Ki4a-ras, Ki4b-ras and N-ras) are found in many human cancers, including colorectal carcinoma, exocrine pancreatic carcinoma, and myeloid leukemias. The protein products of these genes are defective in their GTPase activity and constitutively transmit a growth stimulatory signal.
Ras must be localized to the plasma membrane for both normal and oncogenic functions. At least 3 post-translational modifications are involved with Ras membrane localization, and all 3 modifications occur at the C-terminus of Ras. The Ras C-terminus contains a sequence motif termed a "CAAX" or "Cys-Aaal-Aaa 2 -Xaa" box (Cys is cysteine, Aaa is an aliphatic amino acid, the Xaa is any amino acid) (Willumsen et al., Nature 310:583-586 (1984)). Depending on the specific sequence, this motif serves as a signal sequence for the enzymes famesyl-protein transferase or geranylgeranyl-protein transferase, which catalyze the alkylation of the cysteine residue of the CAAX motif with a C15 or C20 isoprenoid, respectively. Clarke., Ann. Rev. Biochem. 61:355-386 (1992); W.R. Schafer and J. Rine, Ann. Rev. Genetics 30:209-237 (1992)). The Ras protein is one of several proteins that are known to undergo post-translational WO 97/36591 PCT/US97/04750 -2famesylation. Other faresylated proteins include the Ras-related GTPbinding proteins such as Rho, fungal mating factors, the nuclear lamins, and the gamma subunit of transducin. James, et al., J. Biol. Chem. 269, 14182 (1994) have identified a peroxisome associated protein Pxf which is also farnesylated. James, et al., have also suggested that there are famesylated proteins of unknown structure and function in addition to those listed above.
Inhibition of faresyl-protein transferase has been shown to block the growth of Ras-transformed cells in soft agar and to modify other aspects of their transformed phenotype. It has also been demonstrated that certain inhibitors of famesyl-protein transferase selectively block the processing of the Ras oncoprotein intracellularly Kohl et al., Science, 260:1934-1937 (1993) and G.L. James et al., Science, 260:1937-1942 (1993). Recently, it has been shown that an inhibitor of faresyl-protein transferase blocks the growth of rasdependent tumors in nude mice Kohl et al., Proc. Natl. Acad. Sci 91:9141-9145 (1994) and induces regression of mammary and salivary carcinomas in ras transgenic mice Kohl et al., Nature Medicine, 1:792-797 (1995).
Indirect inhibition of faresyl-protein transferase in vivo has been demonstrated with lovastatin (Merck Co., Rahway, NJ) and compactin (Hancock et al., ibid; Casey et al., ibid; Schafer et al., Science 245:379 (1989)). These drugs inhibit HMG-CoA reductase, the rate limiting enzyme for the production of polyisoprenoids including famesyl pyrophosphate. Farnesyl-protein transferase utilizes faresyl pyrophosphate to covalently modify the Cys thiol group of the Ras CAAX box with a famesyl group (Reiss et al., Cell, 62:81-88 (1990); Schaber et al., J. Biol. Chem., 265:14701-14704 (1990); Schafer et al., Science, 249:1133-1139 (1990); Manne et al., Proc. Natl. Acad. Sci USA, 87:7541-7545 (1990)). Inhibition of faresyl pyrophosphate biosynthesis by inhibiting HMG-CoA reductase blocks Ras membrane localization in cultured cells. However, direct inhibition of faresylprotein transferase would be more specific and attended by fewer side WO 97/36591 PCT/US97/04750 -3effects than would occur with the required dose of a general inhibitor of isoprene biosynthesis.
Inhibitors of famesyl-protein transferase (FPTase) have been described in two general classes. The first are analogs of farnesyl diphosphate (FPP), while the second class of inhibitors is related to the protein substrates Ras) for the enzyme. The peptide derived inhibitors that have been described are generally cysteine containing molecules that are related to the CAAX motif that is the signal for protein prenylation. (Schaber et al., ibid; Reiss et. al., ibid; Reiss et al., PNAS, 88:732-736 (1991)). Such inhibitors may inhibit protein prenylation while serving as alternate substrates for the faresyl-protein transferase enzyme, or may be purely competitive inhibitors (U.S.
Patent 5,141,851, University of Texas; N.E. Kohl et al., Science, 260:1934-1937 (1993); Graham, et al., J. Med. Chem., 37, 725 (1994)).
In general, deletion of the thiol from a CAAX derivative has been shown to dramatically reduce the inhibitory potency of the compound.
However, the thiol group potentially places limitations on the therapeutic application of FPTase inhibitors with respect to pharmacokinetics, pharmacodynamics and toxicity. Therefore, a functional replacement for the thiol is desirable.
It has recently been reported that faresyl-protein transferase inhibitors are inhibitors of proliferation of vascular smooth muscle cells and are therefore useful in the prevention and therapy of arteriosclerosis and diabetic disturbance of blood vessels (JP H7- 112930).
It has recently been disclosed that certain tricyclic compounds which optionally incorporate a piperidine moiety are inhibitors of FPTase (WO 95/10514, WO 95/10515 and WO 95/10516).
Imidazole-containing inhibitors of famesyl protein transferase have also been disclosed (WO 95/09001 and EP 0 675 112 Al).
It is, therefore, an object of this invention to develop peptidomimetic compounds that do not have a thiol moiety, and that will inhibit famesyl-protein transferase and thus, the post-translational famesylation of proteins. It is a further object of this invention to WO 97/36591 PCT/US97/04750 -4develop chemotherapeutic compositions containing the compounds of this invention and methods for producing the compounds of this invention.
SUMMARY OF THE INVENTION The present invention comprises peptidomimetic ketopiperazine-containing compounds which inhibit the farnesyl-protein transferase. The instant compounds lack a thiol moiety and thus offer unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. Further contained in this invention are chemotherapeutic compositions containing these famesyl transferase inhibitors and methods for their production.

The pharmaceutically acceptable salts of the compounds of this invention include the conventional non-toxic salts of the compounds of this invention as formed, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like: and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxy-benzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, trifluoroacetic and the like.
The pharmaceutically acceptable salts of the compounds of this invention can be synthesized from the compounds of this invention which contain a basic moiety by conventional chemical methods.
Generally, the salts are prepared either by ion exchange WO 97/36591 PCT/US97/04750 -36 chromatography or by reacting the free base with stoichiometric amounts or with an excess of the desired salt-forming inorganic or organic acid in a suitable solvent or various combinations of solvents.
Reactions used to generate the compounds of this invention are prepared by employing reactions as shown in the Schemes 1-14, in addition to other standard manipulations such as ester hydrolysis, cleavage of protecting groups, etc., as may be known in the literature or exemplified in the experimental procedures.
These reactions may be employed in a linear sequence to provide the compounds of the invention or they may be used to synthesize fragments which are subsequently joined by the alkylation reactions described in the Schemes.
Synopsis of Schemes 1-14: The requisite intermediates are in some cases commercially available, or can be prepared according to literature procedures, for the most part. 2-Piperazinones can be generally prepared as shown in Scheme 1. Amination of the suitably substituted 2-oxazolidinone
I
provides the diamine II. This is then reacted with a suitably substituted bromoacetate to provide the secondary amide III; acid deprotection provides the key intermediate IV. Ring closure to the 2-piperazinones VI occurs concurrently with reductive alkylation with an aldehyde such as the protected imidazolyl aldehyde V. The imidazolyl protecting group may be removed under acidic conditions such as trifluoroacetic acid in methylene chloride. Alternatively, the imidazolyl may be alkylated and then deprotected to provide compounds such as VIII The intermediate IV can be cyclized and reductively alkylated with a variety of aldehydes, such as IX. The aldehydes can be prepared by standard procedures, such as that described by O. P. Goel, U. Krolls, M. Stier and S. Kesten in Organic Syntheses, 1988, 67, 69from the appropriate amino acid (Scheme The reductive alkylation can be accomplished at pH 5-7 with a variety of reducing agents, such as sodium triacetoxyborohydride or sodium cyanoborohydride in a solvent such as dichloroethane, methanol or WO 97/36591 PCT/US97/04750 -37 dimethylformamide. The product X can be deprotected to give the final compounds XI with trifluoroacetic acid in methylene chloride. The final product XI is isolated in the salt form, for example, as a trifluoroacetate, hydrochloride or acetate salt, among others. The product diamine XI can further be selectively protected to obtain XII, which can subsequently be reductively alkylated with a second aldehyde to obtain XIII. Removal of the protecting group, and conversion to cyclized products such as the dihydroimidazole XV can be accomplished by literature procedures.
As shown in Scheme 3, the imidazole acetic acid XVI can be converted to the acetate XVII by standard procedures, and the protected imidazole XVIII can be first reacted with an alkyl halide, then treated with refluxing methanol to provide the regiospecifically alkylated imidazole acetic acid ester XIX. The ester is hydrolyzed and the acid converted to the acid chloride. Reaction with the suitably substituted lithium diketopiperazine XXI in the presence of condensing reagents such as 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide
(EDC)
leads to acylated products such as XXII.
If the intermediate IV is cyclized/reductively alkylated with an aldehyde which also has a protected hydroxyl group, such as XXIII in Scheme 4, the protecting groups can be subsequently removed to unmask the hydroxyl group (Schemes 4, The alcohol can be oxidized under standard conditions to e.g. an aldehyde, which can then be reacted with a variety of organometallic reagents such as Grignard reagents, to obtain secondary alcohols such as XXVII. In addition, the fully deprotected amino alcohol XXV can be reductively alkylated (under conditions described previously) with a variety of aldehydes to obtain secondary amines, such as XXIX (Scheme or tertiary amines.
The Boc protected amino alcohol XXV can also be utilized to synthesize 2-aziridinylmethylpiperazines such as XXX (Scheme 6).
Treating XXV with 1,1'-sulfonyldiimidazole and sodium hydride in a solvent such as dimethylformamide led to the formation of aziridine XXX. The aziridine reacted in the presence of a nucleophile, such as a WO 97/36591 PCT/US97/04750 38 thiol, in the presence of base to yield, after deprotection, the ringopened product XXXII.
In addition, the intermediate IV can be reacted with aldehydes derived from amino acids such as O-alkylated tyrosines, according to standard procedures, to obtain compounds such as XXXV as shown in Scheme 7. When R' is an aryl group, XXXV can first be hydrogenated to unmask the phenol, and the amine group deprotected with acid to produce XXXVI. Alternatively, the amine protecting group in XXXV can be removed, and O-alkylated phenolic amines such as XXXVII produced.
Reaction Scheme 8 provides an illustrative example the synthesis of compounds of the instant invention wherein the substituents
R
4 and R 5 are combined to form (CH2)u For example, 1aminocyclohexan-l-al XXXVIII can be converted to the intermediate IXL essentially according to the procedures outlined in Schemes 1 and 2. The intermediate IXL can be deprotected as before, and carried on to final products as described in Schemes 3-7. It is understood that reagents utilized to provide the imidazolylalkyl substituent may be readily replaced by other reagents well known in the art and readily available to provide other N-substituents on the piperazine.
Scheme 9 illustrates the use of an optionally substituted homoserine lactone XLII to prepare a Boc-protected intermediate XLIII. Intermediate XLIII may be deprotected and cyclized/reductively alkylated or acylated as illustrated in the previous Schemes.
Alternatively, the hydroxyl moiety of diketopiperazine XLIV may be mesylated and displaced by a suitable nucleophile, such as the sodium salt of ethane thiol, to provide an the sulfide XLV. Diketopiperazine XLIV may also be oxidized to provide the carboxylic acid on diketopiperazine XLVI, which can be further utilized to form an ester or amide moiety.
Amino acids of the general formula XLVIII which have a sidechain not found in natural amino acids may be prepared by the reactions illustrated in Scheme 10 starting with the readily prepared imine XLVII.
WO 97/36591 PCT/US97/04750 -39 Schemes 11-14 illustrate syntheses of suitably substituted aldehydes useful in the syntheses of the instant compounds wherein the variable W is present as a pyridyl moiety. Similar synthetic strategies for preparing alkanols that incorporate other heterocyclic moieties for variable W are also well known in the art.

I M M WO 97/36591 PCT/US97/04750 -61 The instant compounds are useful as pharmaceutical agents for mammals, especially for humans. These compounds may be administered to patients for use in the treatment of cancer. Examples of the type of cancer which may be treated with the compounds of this invention include, but are not limited to, colorectal carcinoma, exocrine pancreatic carcinoma, myeloid leukemias and neurological tumors.
Such tumors may arise by mutations in the ras genes themselves, mutations in the proteins that can regulate Ras activity neurofibromin neu, scr, abl, Ick, fyn) or by other mechanisms.
The compounds of the instant invention inhibit famesylprotein transferase and the farnesylation of the oncogene protein Ras.
The instant compounds may also inhibit tumor angiogenesis, thereby affecting the growth of tumors Rak et al. Cancer Research, 55:4575- 4580 (1995)). Such anti-angiogenesis properties of the instant compounds may also be useful in the treatment of certain forms of blindness related to retinal vascularization.
The compounds of this invention are also useful for inhibiting other proliferative diseases, both benign and malignant, wherein Ras proteins are aberrantly activated as a result of oncogenic mutation in other genes the Ras gene itself is not activated by mutation to an oncogenic form) with said inhibition being accomplished by the administration of an effective amount of the compounds of the invention to a mammal in need of such treatment. For example, a component of NF-1 is a benign proliferative disorder.
The instant compounds may also be useful in the treatment of certain viral infections, in particular in the treatment of hepatitis delta and related viruses Glenn et al. Science, 256:1331-1333 (1992).
The compounds of the instant invention are also useful in the prevention of restenosis after percutaneous transluminal coronary angioplasty by inhibiting neointimal formation Indolfi et al. Nature medicine, 1:541-545(1995).
The instant compounds may also be useful in the treatment and prevention of polycystic kidney disease Schaffner et al.
WO 97/36591 PCT/US97/04750 62 American Journal of Pathology, 142:1051-1060 (1993) and B. Cowley, Jr. et al.FASEB Journal, 2:A3160 (1988)).
The instant compounds may also be useful for the treatment of fungal infections.
The compounds of this invention may be administered to mammals, preferably humans, either alone or, preferably, in combination with pharmaceutically acceptable carriers or diluents, optionally with known adjuvants, such as alum, in a pharmaceutical composition, according to standard pharmaceutical practice. The compounds can be administered orally or parenterally, including the intravenous, intramuscular, intraperitoneal, subcutaneous, rectal and topical routes of administration.
For oral use of a chemotherapeutic compound according to this invention, the selected compound may be administered, for example, in the form of tablets or capsules, or as an aqueous solution or suspension. In the case of tablets for oral use, carriers which are commonly used include lactose and corn starch, and lubricating agents, such as magnesium stearate, are commonly added. For oral administration in capsule form, useful diluents include lactose and dried corn starch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents.
If desired, certain sweetening and/or flavoring agents may be added.
For intramuscular, intraperitoneal, subcutaneous and intravenous use, sterile solutions of the active ingredient are usually prepared, and the pH of the solutions should be suitably adjusted and buffered. For intravenous use, the total concentration of solutes should be controlled in order to render the preparation isotonic.
The compounds of the instant invention may also be coadministered with other well known therapeutic agents that are selected for their particular usefulness against the condition that is being treated.
For example, the instant compounds may be useful in combination with known anti-cancer and cytotoxic agents. Similarly, the instant compounds may be useful in combination with agents that are effective in the treatment and prevention of NF-I, restenosis, polycystic kidney WO 97/36591 PCT/US97/04750 -63 disease, infections of hepatitis delta and related viruses and fungal infections.
If formulated as a fixed dose, such combination products employ the compounds of this invention within the dosage range described below and the other pharmaceutically active agent(s) within its approved dosage range. Compounds of the instant invention may alternatively be used sequentially with known pharmaceutically acceptable agent(s) when a combination formulation is inappropriate.
The present invention also encompasses a pharmaceutical composition useful in the treatment of cancer, comprising the administration of a therapeutically effective amount of the compounds of this invention, with or without pharmaceutically acceptable carriers or diluents. Suitable compositions of this invention include aqueous solutions comprising compounds of this invention and pharmacologically acceptable carriers, saline, at a pH level, 7.4. The solutions may be introduced into a patient's blood-stream by local bolus injection.
When a compound according to this invention is administered into a human subject, the daily dosage will normally be determined by the prescribing physician with the dosage generally varying according to the age, weight, and response of the individual patient, as well as the severity of the patient's symptoms.
In one exemplary application, a suitable amount of compound is administered to a mammal undergoing treatment for cancer. Administration occurs in an amount between about 0.1 mg/kg of body weight to about 60 mg/kg of body weight per day, preferably of between 0.5 mg/kg of body weight to about 40 mg/kg of body weight per day.
The compounds of the instant invention are also useful as a component in an assay to rapidly determine the presence and quantity of farnesyl-protein transferase (FPTase) in a composition.
Thus the composition to be tested may be divided and the two portions contacted with mixtures which comprise a known substrate of FPTase (for example a tetrapeptide having a cysteine at the amine WO 97/36591 PCT/US97/04750 64 terminus) and famesyl pyrophosphate and, in one of the mixtures, a compound of the instant invention. After the assay mixtures are incubated for an sufficient period of time, well known in the art, to allow the FPTase to famrnesylate the substrate, the chemical content of the assay mixtures may be determined by well known immunological, radiochemical or chromatographic techniques.
Because the compounds of the instant invention are selective inhibitors of FPTase, absence or quantitative reduction of the amount of substrate in the assay mixture without the compound of the instant invention relative to the presence of the unchanged substrate in the assay containing the instant compound is indicative of the presence of FPTase in the composition to be tested.
It would be readily apparent to one of ordinary skill in the art that such an assay as described above would be useful in identifying tissue samples which contain famrnesyl-protein transferase and quantitating the enzyme. Thus, potent inhibitor compounds of the instant invention may be used in an active site titration assay to determine the quantity of enzyme in the sample. A series of samples composed of aliquots of a tissue extract containing an unknown amount of famesyl-protein transferase, an excess amount of a known substrate of FPTase (for example a tetrapeptide having a cysteine at the amine terminus) and farnesyl pyrophosphate are incubated for an appropriate period of time in the presence of varying concentrations of a compound of the instant invention. The concentration of a sufficiently potent inhibitor one that has a Ki substantially smaller than the concentration of enzyme in the assay vessel) required to inhibit the enzymatic activity of the sample by 50% is approximately equal to half of the concentration of the enzyme in that particular sample.
EXAMPLES
Examples provided are intended to assist in a further understanding of the invention. Particular materials employed, species WO 97/36591 PCT/US97/04750 and conditions are intended to be further illustrative of the invention and not limitative of the reasonable scope thereof.
EXAMPLE 1 4-(3-Chlorophenyl)-l-[1-(4-cyanobenzyl)-5-imidazolylmethyl]-2piperazinone hydrochloride Step A: Preparation of 1-triphenylmethyl-4-(hydroxymethyl)imidazole To a solution of 4-(hydroxymethyl)imidazole hydrochloride (35.0 g, 260 mmol) in 250 mL of dry DMF at room temperature was added triethylamine (90.6 mL, 650 mmol). A white solid precipitated from the solution. Chlorotriphenylmethane (76.1 g, 273 mmol) in 500 mL of DMF was added dropwise. The reaction mixture was stirred for 20 hours, poured over ice, filtered, and washed with ice water. The resulting product was slurried with cold dioxane, filtered, and dried in vacuo to provide the titled product as a white solid which was sufficiently pure for use in the next step.
Step B: Preparation of 1-triphenylmethyl-4-(acetoxymethyl)imidazole Alcohol from Step A (260 mmol, prepared above) was suspended in 500 mL of pyridine. Acetic anhydride (74 mL, 780 mmol) was added dropwise, and the reaction was stirred for 48 hours during which it became homogeneous. The solution was poured into 2 L of EtOAc, washed with water (3 x 1 5% aq. HC1 soln. (2 x 1 L), sat. aq. NaHCO3, and brine, then dried (Na 2 SO4), filtered, and concentrated in vacuo to provide the crude product. The acetate was isolated as a white powder (85.8 g, 86% yield for two steps) which was sufficiently pure for use in the next reaction.
Step C: Preparation of 1-(4-cyanobenzyl)-5-(acetoxymethyl)imidazole hydrobromide WO 97/36591 PCT/US97/04750 66 A solution of the product from Step B (85.8 g, 225 mmol) and a-bromo-p-tolunitrile (50.1 g, 232 mmol) in 500 mL of EtOAc was stirred at 60 °C for 20 hours, during which a pale yellow precipitate formed. The reaction was cooled to room temperature and filtered to provide the solid imidazolium bromide salt. The filtrate was concentrated in vacuo to a volume 200 mL, reheated at 60 °C for two hours, cooled to room temperature, and filtered again. The filtrate was concentrated in vacuo to a volume 100 mL, reheated at 60 OC for another two hours, cooled to room temperature, and concentrated in vacuo to provide a pale yellow solid. All of the solid material was combined, dissolved in 500 mL of methanol, and warmed to 60 oC.
After two hours, the solution was reconcentrated in vacuo to provide a white solid which was triturated with hexane to remove soluble materials. Removal of residual solvents in vacuo provided the titled product hydrobromide as a white solid (50.4 g, 67% yield, 89% purity by HPLC) which was used in the next step without further purification.
Step D: Preparation of 1-(4-cyanobenzyl)-5-(hydroxymethyl)imidazole To a solution of the acetate from Step C (50.4 g, 150 mmol) in 1.5 L of 3:1 THF/water at 0 OC was added lithium hydroxide monohydrate (18.9 g, 450 mmol). After one hour, the reaction was concentrated in vacuo, diluted with EtOAc (3 and washed with water, sat. aq. NaHCO 3 and brine. The solution was then dried (Na 2
