calyculin-a

InvivoChem Cat #:V3631CAS #:101932-71-2Purity >=98%

Description: Calyculin A is a novel, potent, selective and cell-permeable inhibitor of protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A) with IC50s of 0.5 to 1 nM. Calyculin A is a natural product and a marine toxin isolated from Disodermia calyx. Calyculin A does not have significant effect against PP2B, PP2C, and PP4.2 Through its effects on PP1 and PP2A, calyculin A has been shown to either promote or inhibit cancer cell growth in tumor cell lines and animal models.
