Description: FTI-276 is a potent and selective farnesyltransferase inhibitor, which is also a tetrapeptide mimetic of the carboxyl terminus of K-Ras4B. FTI-276 blocked the growth in nude mice of a human lung carcinoma that expresses the two most prevalent genetic alterations in human cancers (K-Ras oncogenic mutation and deletion in the tumor suppressor gene p53). In contrast, FTI-276 did not inhibit tumor growth of a human lung carcinoma that harbors no Ras mutations. Furthermore, FTI-276 inhibited oncogenic signaling and tumor growth of NIH 3T3 cells transformed with the ras but not the raf oncogene.
