Apcin

Apcin is an inhibitor of the E3 ligase activity of the mitotic anaphase-promoting complex/cyclosome (APC/C). Apcin competitively binds to Cdc20 and prevents substrate interaction and ubiquitylation required for continuation of mitosis. Apcin enhances the effect of the APC/C inhibitor N-4-tosyl-L-arginine methyl ester (TAME, Cay-17550) and its prodrug, proTAME, leading to an increase in the number of cells in mitosis, a longer mitotic duration, and greater stabilization of cyclin B1, cycB1-NT, securin, and cyclin A2. Apcin, in combination with proTAME, synergistically increases apoptosis in multiple myeloma cells.Formal Name: [2,2,2-trichloro-1-(2-pyrimidinylamino)ethyl]-carbamic acid, 2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethyl ester.
