Description and Uses
Cantharidin (56-25-7) inhibits protein phosphatase 2A (Ki=0.19 μM) and PP1 (Ki=1.1 μM).1 Displays >500-fold selectivity over PP2B. Suppresses growth and migration of PANC-1 pancreatic cancer cells via phosphorylation and degradation of β-catenin.2?Cantharidin arrests G2/M transition via JNK/Sp1-dependent down-regulation of CDK1.3?Cell permeable. Warning: Avoid skin contact, may cause skin irritation or blistering.
Cantharidin is used as a potent inhibitor of PP2A phosphatase activity. It has been shown to stimulate cell cycle progression and induce premature mitosis, used topically (0.7%) as an anti-wart treatment, and has been shown to be active in cervical, tongue, neuroblastoma, bone, leukemia, ovarian, colon, and various other cancer cell lines.
