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.
(S)-Higenamine hydrobromide, an S-enantiomer of Higenamine, serves as the preliminary compound in benzylisoquinoline alkaloid biosynthesis. It is formed through the condensation of dopamine and 4-hydroxyphenylacetaldehyde (4-HPAA) via norcoclaurine synthase (NCS)[1].
