MedKoo CAT#: 206079

CAS#: 5373-42-2

Description: Thalicarpine is a natural aporphine benzylisoquinoline vinca alkaloid with antineoplastic activity. Thalicarpine binds to and inhibits p-glycoprotein, the multidrug resistance efflux pump. Thalicarpine also induces single-strand breaks in DNA and arrests cancer cells at the G2/M and G1 phase of the cell cycle. Check for active clinical trials or closed clinical trials using this agent.
