Lycorine hydrochloride 是石蒜的主要活性成分,也是黑色素瘤血管生成抑制剂,具有抗肿瘤活性。Lycorine hydrochloride 能有效抑制 Hey1B 细胞的有丝分裂增殖 (IC50为 1.2 μM)。
生物活性 | Lycorine hydrochloride is the main active ingredient of the herbal medicine derived fromLycoris radiata(L’Her.) Herb.and is also a melanoma vasculogenic inhibitor and has anti-tumor activity[1]. Lycorine hydrochloride effectively inhibits mitotic proliferation of Hey1B cells (IC50of 1.2 μM)[2]. |
IC50& Target | IC50: 1.2 μM (Hey1B cells )[2] |
体外研究 (In Vitro) | 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].
RT-PCR[1] Cell Line: | C8161 cells | Concentration: | 0 μM, 1.56 μM, 3.13 μM, 6.25 μM, 12.5 μM, 25 μM | Incubation Time: | 48 hours | Result: | Markedly suppressed the expression of VE-cadherin in a dose-dependent manner and also slightly diminished the expression of Sema4D in C8161 cells. |
Western Blot Analysis[1] Cell Line: | C8161 cells | Concentration: | 0 μM, 1.56 μM, 3.13 μM, 6.25 μM, 12.5 μM, 25 μM | Incubation Time: | 48 hours | Result: | Markedly reduced VE-cadherin protein levels in C8161 cells in a dose-dependent fashion. |

体内研究 (In Vivo) | 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].
Animal Model: | 6- to 8-week-old BALB/C nude mice[1] | Dosage: | 0 μg, 7.5 μg, 15 μg | Administration: | Subcutaneous injection; for 14 days | Result: | Showed an inhibitory effect on melanoma cell-mediated tumor vasculogenic mimicry. |
