Hirsutine

White crystalline powder, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from Uncaria rhynchophylla (Miq.) Miq. ex Havil.

Hirsutine, an indole alkaloid of Uncaria rhynchophylla, exhibits anti-cancer activity. Hirsutine induces apoptosis and is a potent Dengue virus inhibitor exhibiting low cytotoxicity[1][2][3].

Hirsutine is a brain penetrant alkaloid from Uncaria rhynchophylla th at exhibit anti-cancer, cardioprotective, anti-hypertensive, and anti-arrhythmic activities. It appears th at hirsutine induces apoptosis in lung cancer cells through opening of mitochondrial permeability transition pore (mPTP). Hirsutine exhibit potent anti-dengue virus activity.
