MedKoo CAT#: 576274

CAS#: 76970-77-9

Description: Cantharidin imide is a PP1/2A inhibitor found in Canarthis vesicatoria. It inhibits proliferation of colorectal cancer cells, increases MCP-1, IL-6, and IL-β levels, and inhibits differentiation and resorptive activity of osteoclasts. This compound can produce severe skin inflammation, and is extremely toxic if ingested orally.
