一般說明

一种细胞可渗透的，天然分离的银杏双黄酮类化合物，通过在前剪接体/A复杂阶段阻断对剪接体介导的剪接过程，作为一般的前mRNA剪接抑制剂（在使用HeLa核提取物的剪接测定中，ICmax = 50 µM）。已显示异银杏素治疗以可逆的方式导致HEK293衍生的培养物中的生长停滞，而不会影响细胞活率（33 µM持续24 h）。
天然分离的银杏双黄酮类化合物，通过阻止前剪接体A复合物募集U4/U5/U6 tri-snRNP（稳定的核RNA及其相关蛋白）形成B复合物，作为剪接体介导的前mRNA剪接的细胞可渗透，可逆抑制剂（在使用HeLa核提取物的剪接测定中，IC50和ICmax分别为30和50 µM）。已显示异银杏素治疗以可逆的方式导致HEK293衍生的培养物中的生长停滞，而不会影响细胞活率（33 µM持续24 h）。

Matrix metalloproteinase (MMP)-9 plays a key role in tumor invasion. Inhibitors of MMP-9 were screened from Metasequoia glyptostroboides (Dawn redwood) and one potent inhibitor, isoginkgetin, a biflavonoid, was identified. Noncytotoxic levels of isoginkgetin decreased MMP-9 production profoundly, but up-regulated the
