Description |
Lycorine (hydrochloride) is VE-cadherin inhibitor,and has IC50 of 1.2μM in Hey1B cell.IC50: 1.2μM (Hey1B cell)[2]In vitro:Lycorine (hydrochloride) executed an anti-melanoma vasculogenic effect by inhibiting VE-cadherin gene expression in C8161 cells and caused a decrease in cell surface exposure of VE-cadherin protein. Consistently, LH significantly suppressed VE-cadherin gene promoter activity. [1]Lycorine (hydrochloride) effectively inhibited mitotic proliferation of Hey1B cells (half maximal inhibitory concentration = 1.2 μM) with very low toxicity, resulting in cell cycle arrest at the G2/M transition through enhanced expression of the cell cycle inhibitor p21 and marked down-regulation of cyclin D3 expression. Moreover, LH suppressed both the formation of capillary-like tubes by Hey1B cells cultured in vitro.[2]In vivo: Lycorine effectively suppressed C8161 cell-dominant tumor formation and generation of tumor blood vessels in vivo with low toxicity.[1]Lycorine (hydrochloride) suppressed the formation of the ovarian cancer cell-dominant neovascularization in vivo when administered to Hey1B-xenotransplanted mice, suggest that LH selectively inhibits ovarian cancer cell proliferation and neovascularization and is a potential drug candidate for anti-ovarian cancer therapy.[2]
