Lycorine hydrochloride
CAS No. : 2188-68-3
MCE 国际站:Lycorine hydrochloride
产品活性: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)。
研究领域:Autophagy | Anti-infection
作用靶点:Autophagy | Bacterial | Virus Protease
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.
Lycorine hydrochloride (0-25 μM; 48 hours; C8161 cells) treatment markedly reduces VE-cadherin protein levels in C8161 cells in a dose-dependent fashion.
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.

文献和实验性[67],从而提高蛋白质的表达水平。如果来源于E.coli rrB rRNA操纵子的两个转录终止子T1和T2串联,则效果更好[68]。但其他的许多转录终止子通常情况下都是十分有效的。 3.转录抗终止子 细菌中许多参与氨基酸生物合成的操纵子在其第一个结构基因的5’端含有转录衰减子。衰减子由特定操纵子的氨基酸产物调节。这样关联的带电荷tRNA的存在就会在核糖体剪切之后引导初始转录本中二级结构的形成。如果没有关联的带电荷tRNA,则会形成抗终止子结构,从而抑制终止子中发卡结构的形成和转录的终止[69
子来避免。同样地,在启动目的基因的启动子上游放置一转录终止子,将最大限度地减小背景转录[65]。另有资料证明,由强启动子启动的转录会使转录通读到复制区,造成控制质粒拷贝数的ROP蛋白的过量表达,从而导致质粒的不稳定[66]。另外,转录终止增强mRNA的稳定性[67],从而提高蛋白质的表达水平。如果来源于E.coli rrB rRNA操纵子的两个转录终止子T1和T2串联,则效果更好[68]。但其他的许多转录终止子通常情况下都是十分有效的。 3.转录抗终止子 细菌中许多参与氨
