  Synthesis, cytotoxic activity evaluation and HQSAR study of novel isosteviol derivatives as potential anticancer agents

  摘要：

  A series of novel isosteviol derivatives bearing amino alcohol and thiourea fragments have been stereo selectively synthesized and screened for their in vitro cytotoxic activities against three human cancer cell lines (HCT-116, HGC-27 and JEKO-1). The results demonstrated that these compounds exhibited prominent cytotoxicities. Especially, the compound Iw displayed the most potent anticancer activities against HCT-116 cell with IC50 value of 1.450 mu M. On the basis of this bioassay results, these derivatives were further investigated by the hologram quantitative structure activity relationship (HQSAR) technique. The optimal HQSAR model with q(2) = 0.663, r(2) = 0.895, SEE = 0.179 was generated using A/B/H/Ch as fragment distinction parameters and 4-7 as fragment size. This model was employed to predict the cytotoxic activities of test set compounds, and the predicted values were in good agreement with the experimental results. The contribution maps derived from the optimal model explained the individual atomic contribution to the total activity of single molecule. (C) 2016 Elsevier Masson SAS. All rights reserved.

  具有D环修饰的新型异osteviol衍生物的立体选择性合成，表征和抗菌活性

  摘要：

  异osteviol及其衍生物因其多种生物活性而引起了极大的兴趣。在该项目中，通过四环二萜异戊二烯醇D环中的功能性相互转化，立体选择性地制备了一系列新型的15和16取代的异雌甾醇。通过NMR，IR，HR-MS数据分析对所有合成的化合物进行表征，并通过X射线晶体学分析确定33和37的构型。研究了这些异osteviol衍生物的体外抗菌活性。该合成的化合物针对更活跃的革兰氏阳性比革兰氏阴性细菌，对枯草芽孢杆菌特别活跃。其中，化合物27（MIC = 1.56μg/ ml）表现出最高的抗菌活性，因此可以用作开发有效抗菌剂的先导化合物。

  By means of functional interconversions in ring D of the tetracyclic diterpene isosteviol (ent-16-ketobeyeran-19-oic acid 1), various 15- and 16-substituted isosteviol derivatives were stereoselectively prepared. The cytotoxic activities in vitro of these new isosteviol derivatives were investigated, and some of them showed noteworthy activities against B16-F10 melanoma cells.
