Background

Lonafarnib (SCH66336, Sarasar) is an potent, selective, orally, bioavailable tricyclic nonpeptidyl nonsulfhydry inhibitor of farnesyltransferase (FTase).[1] It is a small molecular with the formula of C27H31Br2ClN4O2 and molecular weight of 638.82. Farnesylated Ras proteins was found to regulate signal transduction pathways which drive cell proliferation, growth and survival and be required for its membrane localization.[1, 2] Lonafarnib inhibits the post-translational farnesylcation of ras proteins, therefore blocking translocation of RAS to the plasma membrane.[3]
