Lycorine hydrochloride is the main active ingredient of the herbal medicine derived from Lycoris radia and is also a melanoma vasculogenic inhibitor and has anti-tumor activity[1]. Lycorine hydrochloride effectively inhibits mitotic proliferation of Hey1B cells (IC50 of 1.2 μM)[2].
Lycorine hydrochloride (0-25 μM; 48 hours; C8161 cells) treatment markedly suppresses the expression of vascular endothelial (VE)-cadherin in a dose-dependent manner and also slightly diminishes the expression of Sema4D in C8161 cells. However, the expression of the other six genes is not affected[1].Lycorine hydrochloride (0-25 μM; 48 hours; C8161 cells) treatment markedly reduces VE-cadherin protein levels in C8161 cells in a dose-dependent fashion[1].
Lycorine hydrochloride (0-15 μg; subcutaneous injection; for 14 days; BALB/C nude mice) treatment has an inhibitory effect on melanoma cell-mediated tumor vasculogenic mimicry[1].
