Biological Activity for Lonafarnib

Lonafarnib is a potent farnesyl transferase inhibitor (IC50 = 1.9 nM). Inhibits farnesylation of RAS. Also inhibits Pgp transport (IC50 < 3 μM) and increases potency and anticancer activity when used in conjunction with cytotoxic Pgp substrates. Inhibits neovascularization by affecting cell motility. Orally bioavailable.
