WebLonafarnib is a potent and orally active tricyclic farnesyl transferase (FTase) inhibitor. Lonafarnib, also known as SCH66336, can inhibit the activities of H-ras, K-ras and N-ras. In addition, Lonafarnib, which competes with the CAAX peptide substrate motif, blocks FTase activity in vitro. In cells, Lonafarnib potently inhibits Ha-Ras processing.
