Ftase inhibitor I (B581) is a potent, selective and peptidomimetic farnesyl transferase (FTase) inhibitor. Ftase inhibitor I shows selectivity for FTase over geranylgeranyl isoprenoid (Ras-GG) or the fatty acid myristate (Myr-Ras)[1].

In Vitro	Ftase inhibitor I (B581) inhibits the ability of only Ras-F-transformed cells, but not geranylgeranyl isoprenoid (Ras-GG) or the fatty acid myristate (Myr-Ras)- (or Raf-) transformed cells, to grow in soft agar[1].
