D-CopA3

D-CopA3 is the inhibitor for MDM2 and the activator for p53 signaling pathway. D-CopA3 exhibits cytotoxicity in colorectal cancer cells HCT-116, LoVo, and RKO (IC50=15-18 μM), induces JNK/Beclin-1 mediated autophagy. D-CopA3 downregulates the expression of cell cycle inhibitory protein p21Cip1/Waf1, enhances the mucosal barrier function and reduces penetration of inflammatory mediators. D-CopA3 exhibits anti-inflammtory activity in mouse C. difficile toxin A-induced acute enteritis models and DSS -induced chronic colitis models. D-CopA3 exhibits antitumor efficacy in mouse HCT-116 xenograft models[1][2].
