    • Focused library synthesis and medicinal chemistry on an oxadiazole-isopropylamide core proteasome inhibitor provided the lead compound that strongly inhibits CT-L activity. Structure activity relationship studies indicate the amide moiety and two phenyl rings are sensitive toward synthetic modifications. Only para-substitution in the A-ring was important to maintain potent CT-L inhibitory activity. Hydrophobic residues in the A-ring's para-position and meta-pyridyl group at the B-ring significantly improved inhibition. The meta-pyridyl moiety improved cell permeability. The length of the aliphatic chain at the para position of the A-ring is critical with propyl yielding the most potent inhibitor, whereas shorter (i.e. ethyl, methyl or hydrogen) or longer (i.e. butyl, propyl and hexyl) chains demonstrating progressively less potency. Introduction of a stereogenic center next to the ether moiety (i.e. substitution of one of the hydrogens by methyl) demonstrated chiral discrimination in proteasome CT-L activity inhibition (the S-enantiomer was 35-40 fold more potent than the R-enantiomer).

    • Many GTPases such as Ras, Ral and Rho require post-translational farnestylation or geranylgeranylation for mediating malignant transformation. Dual farnesyltransferase (FT) (FTI) and geranylgeranyltransferase-l (GGT-1) inhibitors (GGTI) were developed as anticancer agents from based on an ethylenediamine scaffold. On the basis of a 4-fold substituted ethylenediamine scaffold, the inhibitors are structurally simple and readily derivatized, facilitating extensive structure-activity relationship studies. The most potent inhibitor is compound exhibited an in vitro hFTase IC50 value of 25 nM and a whole cell H-Ras processing IC50 value of 90 nM. Several of the inhibitors proved highly selective for hFTase over the related prenyltransferase enzyme geranylgeranyltransferase-l (GGTase-l). A crystal structure of an inhibitor cocrystallized with farnesyl pyrophosphate in the active site of rat FTase illustrates that the para-benzonitrile moiety is stabilized by a p-p stacking interaction with the Y361 ß residue, suggesting an importance of this component of the inhibitors.
