Tipifarnib (Cat No.: I002461) is a highly potent and selective inhibitor of farnesyltransferase (FTase), an enzyme involved in protein prenylation. It exerts its most significant antiproliferative effects in cells with mutations in H-ras or N-ras genes. By inhibiting FTase, Tipifarnib disrupts the prenylation process critical for the activation of Ras proteins, which are involved in cell signaling and growth. This specific targeting of mutant Ras-driven pathways makes Tipifarnib a promising candidate for cancer therapy, particularly in cases where Ras mutations play a prominent role in the disease’s progression.
