85-2073-65　ICMT Inhibitor (Cysmethynil) 1mg　CAS No:851636-83-4　217447

特徴

• An inhibitor of protein prenylation. Cysmethynil is a potent inhibitor of isoprenylcysteine carboxyl methyltransferase (ICMT) with antitumor activity in cancer cells. Cysmethynil treatment results in inhibition of cell growth in an Icmt-dependent fashion, demonstrating mechanism-based activity of the compound. Treatment of cancer cells with cysmethynil results in mislocalization of Ras and impaired epidermal growth factor signaling. In a human colon cancer cell line, cysmethynil treatment blocks anchorage-independent growth, and this effect is reversed by overexpression of Icmt.
• A cell-permeable indole acetamide that acts as a substrate-competitive and AdoMet-noncompetitive Icmt (isoprenylcysteine carboxyl methyltransferase) inhibitor (Ki=0.02uM; IC50=0.29uM; Substrate=S-farnesyl-L-cysteine), exhibiting no activity against FTase, gernaylgeranyltransferase type I, CaaX protease Rce1, AdoMet-dependent DNA methyltransferase, SssI DNA methyltransferase, or PCMT1 protein methyltransferase. Cysmethynil (25uM) induces G1 cell cycle-arrest and autophagy-mediated, but not apoptotic, cell death in prostate cancer PC3 cells with concomitant PI 3-K/Akt and mTOR signaling blockage, consistent with inhibition of Icmt-mediated activation of Ras and Rheb GTPases. Murine PC3 xenograft studies reveal limited in vivo efficacy.
