Abstract
A three-dimensional pharmacophore model was developed based on 25 currently available inhibitors, which were carefully selected with great diversity in both molecular structure and bioactivity as required by HypoGen program in the Catalyst software, for discovering new farnesyltransferase (FTase) inhibitors. The best hypothesis (Hypo1), consisting of four features, namely, two hydrogen-bond acceptors, one hydrophobic point, and one ring aromatic feature, has a correlation coefficient of 0.949, a root-mean-square deviation of 1.321, and a cost difference of 163.15, suggesting that a highly predictive pharmacophore model was successfully obtained. The application of the model shows great success in predicting the activities of 227 known FTase inhibitors in our test set with a correlation coefficient of 0.776 with a cross-validation of 98% confidence level. Accordingly, our model should be reliable in identifying structurally diverse compounds with desired biological activity.

Abstract
Farnesyl:protein transferase (FPTase) catalyzes the covalent addition of the isoprenyl moiety of farnesylpyrophosphate to the C-terminus of the Ras oncoprotein and other cellular proteins. Inhibitors of FPTase (FTIs) have been developed as potential anticancer agents, and several compounds have been evaluated in clinical trials. To facilitate the identification of cell-active FTIs with high potency, the authors developed a method that uses a radiolabeled FTI that serves as a ligand in competitive displacement assays. Using high-affinity [(3)H]-labeled or [(125)I]-labeled FTI radioligands, they show that specific binding to FPTase can be detected in intact cells. Binding of these labeled FTI radioligands can be competed with a variety of structurally diverse FTIs, and the authors show that inhibition of FTI radioligand binding correlates well with inhibition of FPTase substrate prenylation in cells. This method provides a rapid and quantitative means of assessing FTI potency in cells and is useful for guiding the discovery of potent, novel inhibitors of FPTase. Similar methods could be employed in the optimization of inhibitors for other intracellular drug targets.

Abstract
A new synthesis of the 3,8-diazabicyclo[3.2.1]octan-2-one framework is described. Transannular enolate alkylation of piperazinone derivatives provides a flexible route to highly constrained bicyclic peptidomimetic synthons with substitution at the Calpha position. The chemistry was used to produce a conformationally constrained farnesyltransferase inhibitor, which aided the elucidation of enzyme-bound conformation.
