Abstract
This article presents in brief the development of farnesyltransferase inhibitors (FTIs) and their preclinical and clinical status. In this review the mechanism of action of FTIs is discussed and their selectivity issue towards tumor cells is also addressed. The significant efficacy of FTIs as single or combined agents in preclinical studies stands in contrast with only moderate effects in Clinical Phase II-III studies. This suggests that there is a need to further explore and understand the complex mechanism of action of FTIs and their interaction with cytotoxic agents.

Abstract
A study of the prenyl transferase reactions was performed by fluorescence using rat brain cytosol fractions as an enzyme source. Four dansylated peptides corresponding to the C-terminal sequence of Ras isoforms were synthesised. The effects of different detergents on the farnesylation or geranylgeranylation of the four peptides were evaluated. Dose-dependent effects of dodecyl-maltoside, a non-ionic detergent, on the farnesyl transferase or geranylgeranyl transferase activities were observed with all peptide substrates. Additionally, the effect of temperature was investigated and these assays were applied to determine Michaelis-Menten constants (K(m)) of the substrates: dansyl-GCVLS (1.8 microM), dansyl-GCVVM (3.2 microM), dansyl-CVIM (3.4 microM) and dansyl-GCVLL (8.4 microM) and FPP (22.6 microM) for FTase activity. Using GGPP as co-substrate, GGTase activity was measured with K(m) values superior to 50 microM for all the three substrate dansyl-GCVLS, dansyl-GCVVM, or dansyl-CVIM, whereas values of 7.6 and 5.4 microM were calculated for the dansyl-GCVLL sequence and GGPP co-substrate, respectively. IC50 values of selective prenyl transferase inhibitors, B-581, FTI 276 and GGTI 287 have been measured to 34, 0.8 and 18 nM, respectively, using dansyl-GCVLS as substrate (FTase inhibition). When dansyl-GCVLL is used as substrate (GGTase inhibition) the IC50 values are 5100, 75 and 5 nM for B-581, FTI 276 and GGTI 287, respectively. Then, this developed method allowed to evaluate the selectivity of all the three inhibitors tested.

Abstract
We have designed the nitrophenylfurylacryl-substituted benzophenone 4f as a non-thiol farnesyltransferase inhibitor utilizing a novel aryl binding site of farnesyltransferase. Variation of the 2-acylamino substituent at the benzophenone core structure of our initial lead 4f yielded several non-thiol farnesyltransferase inhibitors with improved activity. These compounds display activity in the low nanomolar range.

Abstract
We recently described a novel aryl binding site of farnesyltransferase. The 2-naphthylacryloyl residue was developed as an appropriate substituent for our benzophenone-based AAX-peptidomimetic capable of occupying this binding site, resulting in a non-thiol farnesyltransferase inhibitor with nanomolar activity. The activity of this inhibitor is readily explained on the basis of docking studies which show the 2-naphthyl residue fitting into the aryl binding site.

Abstract
A series of macrocyclic 3-aminopyrrolidinone farnesyltransferase inhibitors (FTIs) has been synthesized. Compared with previously described linear 3-aminopyrrolidinone FTIs such as compound 1, macrocycles such as 49 combined improved pharmacokinetic properties with a reduced potential for side effects. In dogs, oral bioavailability was good to excellent, and increases in plasma half-life were due to attenuated clearance. It was observed that in vivo clearance correlated with the flexibility of the molecules and this concept proved useful in the design of FTIs that exhibited low clearance, such as FTI 78. X-ray crystal structures of compounds 49 and 66 complexed with farnesyltransferase (FTase)-farnesyl diphosphate (FPP) were determined, and they provide details of the key interactions in such ternary complexes. Optimization of this 3-aminopyrrolidinone series of compounds led to significant increases in potency, providing 83 and 85, the most potent inhibitors of FTase in cells described to date.

Abstract
Investigations on the structure-activity relationships of benzophenone-based bisubstrate analogue farnesyltransferase inhibitors yielded a bisubstrate analogue farnesyltransferase inhibitor lacking any prenylic or peptidic substructures with nanomolar activity. This represents a considerable progress in comparison to those non-prenylic, non-peptidic bisubstrate analogue farnesyltransferase inhibitors we have described before which utilized AAX-peptidomimetic substructures different from the benzophenone since those inhibitors displayed activity only in the micromolar range.

Abstract
We have developed the 4-nitrocinnamoyl substituted benzophenone 4a as a novel non-thiol farnesyltransferase inhibitor. Replacement of the p-tolyl moiety of our initial lead structure 4a by different para and ortho substituted phenyl residues as well as by 1-naphthyl resulted in derivatives with considerably enhanced activity displaying IC(50) values between 42 and 52 nM. These compounds represent novel, readily accessible non-thiol farnesyltransferase inhibitors being more active than the corresponding thiol-containing analogues.

Abstract
New CA(1)A(2)X peptidomimetics are described as Ras farnesyl transferase inhibitors (FTIs). They include cysteine and methionine as mimetics of the C-terminus sequence of farnesylated proteins. Furthermore, cysteine was replaced by heterocycles, taking into account the role of zinc and the metabolic instability of amino acids. The molecular docking of 8 in the active site of the enzyme and the pharmacological evaluation of the compounds are illustrative of a new class of FTIs.

Abstract
We describe a novel class of benzophenone-based farnesyltransferase inhibitors exploiting a novel aryl binding region in the farnesyltransferase's active site. The present study was mainly focussed on structural modifications of the trimethylene spacer of the 4-phenyl butyroyl residue of our lead structure (IC50 = 530 nM). These modifications turned out to have little effect on activity as had the replacement of the terminal aryl by cyclohexyl (IC50 = 440 nM vs. IC50 = 530 nM).

Abstract
Continuing structure-activity studies were performed on the 2,3,4, 5-tetrahydro-1-(imidazol-4-ylalkyl)-1,4-benzodiazepine farnesyltransferase (FT) inhibitors. These studies demonstrated that a 3(R)-phenylmethyl group, a hydrophilic 7-cyano group, and a 4-sulfonyl group bearing a variety of substituents provide low-nanomolar FT inhibitors with cellular activity at concentrations below 100 nM. Maximal in vivo activity in the mutated K-Ras bearing HCT-116 human colon tumor model was achieved with analogues carrying hydrophobic side chains such as propyl, phenyl, or thienyl attached to the N-4 sulfonyl group. Several such compounds achieved curative efficacy when given orally in this model. On the basis of its excellent preclinical antitumor activity and promising pharmacokinetics, compound 20 (BMS-214662, (R)-7-cyano-2,3,4, 5-tetrahydro-1-(1H-imidazol-4-ylmethyl)-3-(phenylmethyl)-4-(2-thie nyl sulfonyl)-1H-1,4-benzodiazepine) has been advanced into human clinical trials.

Abstract
Cancer as a disease in the human population is becoming a larger health problem, and the medicines used as treatments have clear limitations. In the past 20 years, there has been a tremendous increase in our knowledge of the molecular mechanisms and pathophysiology of human cancer. Many of these mechanisms have been exploited as new targets for drug development in the hope that they will have greater antitumor activity with less toxicity to the patient than is seen with currently used medicines. The fruition of these efforts in the clinic is just now being realized with a few encouraging results.
