A cell-permeable inhibitor of apoptosis induction. Inhibits caspase-3 activation but does not directly inhibit caspase-3 even at 1 mg/ml.

ChEBI: 2-[(2,6-dioxocyclohexyl)methyl]cyclohexane-1,3-dione is a beta-diketone.

m50054, 2,2'-methylenebis (1,3-cyclohexanedione), is a novel inhibitor of apoptosis. [1]in human fas-expressing wc8 cells, m50054 inhibited apoptosis by soluble human fas ligand in vitro cell death assay. m50054 inhibited the apoptotic u937 cell death which is a human monocytic leukemic cell line, induced by anticancer agents such as etoposide. m50054 inhibited apoptotic characters such as dna phosphatidylserine and fragmentation exposure in these cells. these anti-apoptotic effects were dependent on inhibition of caspase-3 activation. additionally, m50054 significantly inhibited anti-fas-antibody-induced elevation of plasma aspartate aminotransferase and alanine aminotransferase. alopecia (hair loss) symptoms were also significantly improved with topical treatment with m50054. m50054 inhibits apoptosis induced by a variety of stimuli via inhibition of caspase-3 activation, and may thus be effective for hepatitis and chemotherapy-induced alopecia.
