一般描述
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

Deposition and dysfunction of U1 small nuclear ribonucleoprotein (snRNP) have been revealed in Alzheimer's disease (AD), but whether U1 is involved in the amyloid precursor protein (APP) and Tau pathways remains unclear. Here, we investigate this by inhibiting the U1

Membrane-permeable compounds that reversibly inhibit a particular step in gene expression are highly useful tools for cell biological and biochemical/structural studies. In comparison with other gene expression steps where multiple small molecule effectors are available, very few compounds have been
