AZD-3409 is a potent prenyl transferase inhibitor. AZD-3409 showed higher potency than lonafarnib. The mean IC(50) for cytotoxicity of AZD3409 was 510 in MEF cells, 10,600 in A549 cells and 6,170 in MCF7 cells, respectively. In these cells, the IC(50) for FTase activity of AZD3409 ranged from 3.0 to 14.2 nM and of lonafarnib from 0.26 to 31.3 nM. AZD3409 inhibits farnesylation to a higher extent than geranylgeranylation. Both inhibition of farnesylation and geranylgeranylation could not be correlated to the antiproliferative activity of the drug. AZD3409 might be active in gefitinib-resistant breast carcinoma.

Tipifarnib (IND 58359) is a nonpeptidomimetic quinolinone with potential antineoplastic activity. Tipifarnib binds to and inhibits the enzyme farnesyl protein transferase, an enzyme involved in protein processing (farnesylation) for signal transduction. By inhibiting the farnesylation of proteins, this agent prevents the activation of Ras oncogenes, inhibits cell growth, induces apoptosis, and inhibits angiogenesis.

BIM-46050 is a potent and specific inhibitor of human farnesyltransferase. BIM-46050 is free acidic form of BIM-46068. The IC50 values for in vitro inhibition of human brain FTase indicate that BIM-46050 and the ester form BIM-46068 are potent inhibitors of farnesyltransferase. Their potencies are in the nanomolar range and compare favorably with the compounds B581, FTI-277 and L745,631.
