Description : Capsaicin is an anti-proliferation agent with IC50 value of 100 M in A172 cells. Capsaicin is an active component of chili peppers. It selectively binds to TRPV1 which is a heat-activated calcium channel. Capsaicin causes the channel to open below 37 C. This is why capsaicin is linked to the sensation of heat. [1] Capsaicin has been reported to possess anti-carcinogenic and anti-mutagenic activities. In human glioma A172 cells, capsaicin reduced cell viability with IC50 of 100 M treated for 1 day. Capsaicin inhibited cell growth and induced apoptosis through down-regulation of Bcl-2 and activation of caspase-3. Capsaicin also induced terminal differentiation, which contribute to A172 cell growth inhibition.[2] On the other hand, capsaicin reduced the basal generation of ROS, which may played a role in the induction of apoptosis by capsaicin.[3] In MCF-7 cells, Capsaicin induced cell apoptosis through the mitochondrial pathway, and subsequently caused PARP-1 cleaved by activation of caspase-7.[4] In human SCLC cell line, capsaicin displayed robust anti-proliferative activity with MTT assay. Furthermore, capsaicin (10 mg/kg body weight) significantly reduced the growth rate of established (800 mm3) H69 tumors xenotransplanted in nude mice. [5] References:1. M. J. Caterina, M. A.
