focussed biological activities of this library were also investigated; quorum sensing activity of Vibrio harveyi was envisaged and some of the new compounds were shown to be good quorum sensing inhibitor candidates, whereas others were activators. Toxicities were also evaluated and some products showed micromolar activities against human umbilical vein endothelium, human hepatocellular carcinoma and human
我们在此报告了一种应用于海洋天然物质 ilimaquinone 和 5-epi-ilimaquinone 的环扭曲策略。合成了一个化学多样化的分子库,包括倍半萜部分的重排和醌环的原始重组。化学信息学分析评估了结构多样性的兴起和化学空间的探索。还研究了该文库的一些重点生物活性;设想了哈维弧菌的群体感应活性,并且一些新化合物被证明是良好的群体感应抑制剂候选物,而其他化合物则是激活剂。还评估了毒性,一些产品显示出对人脐静脉内皮、人肝细胞癌和人肺癌 (A549) 细胞的微摩尔活性。
