  摘要：

  描述了通过芳基溴化物或芳基三氟甲磺酸酯与硫代乙酸钾酯的杂交联反应制备S-芳基硫代乙酸酯的温和方法。反应在110°C的甲苯中顺利进行，这是由催化性Pd 2（dba）3与CyPF- t Bu作为配体的结合介导的。既不需要存在碱也不需要微波条件。形成的S-芳基硫代乙酸酯证明在快速色谱条件下稳定，在温和的碱性条件下可以快速转化为相应的硫醇。

  A mild method for the preparation of S-aryl thioacetates by hetero cross-coupling reactions of aryl bromides or aryl triflates with potassium thioacetate is described. The reaction proceeded smoothly in toluene at 110 °C, mediated by catalytic Pd2(dba)3 in combination with CyPF-tBu as the ligand. Neither the presence of a base nor microwave conditions were required. The formed S-aryl thioacetate proved

  minimal cytotoxicity to normal cells. In this manuscript, we report the design and synthesis of substituted benzylthioquinolinium iodides, evaluated their anti-infective properties and formulated some initial structure–activity relationships around phenyl ring A from the original natural product. The sensitivity of the most potent analog 10l, to selected strains of C. cerevisiae was also evaluated leading

  机会性感染对免疫功能低下的患者来说是毁灭性的。特别是在艾滋病流行仍在肆虐的撒哈拉以南非洲地区，死亡率最近高达70%。抗机会性药物的缺乏、疗效下降和对唑类甚至两性霉素 B 的耐药性的发展刺激了对具有新作用机制的新药的研究。在之前的一项工作中，我们发现源自天然产物隐大麻素的新化学型对机会性病原体显示出选择性毒性，而对正常细胞的细胞毒性最小。在这份手稿中，我们报告了取代的苄基硫代喹啉碘化物的设计和合成，评估了它们的抗感染特性，并从原始天然产物中围绕苯环 A 制定了一些初始结构-活性关系。最强大模拟的灵敏度如图 10l 所示，还对选定的酿酒酵母菌株进行了评估，导致观察到该支架可能具有与其前身隐甘平不同的作用模式。

  suitable for many types of sulfur substrates (thiols, disulfides, and benzylic sulfides). The overall process is simple, practical, and it provides convenient access to a variety of aryl or heteroarylsulfonyl chlorides. The mild reaction conditions and the broad substrate scope render this method attractive and complementary to existing syntheses of aryl or heteroarylsulfonyl chlorides.

  The 3-dimensional quantitative structure-activity relationship (3D-QSAR) molecular modeling technique or comparative molecular field analysis (CoMFA) has been used to design analogs of the natural product cryptolepine (1). Twenty-three compounds with their in vitro biological activities (IC50 values) against Crytococcus neoformans were used to generate the training set database of compounds for the CoMFA studies. The cross-validated q(2), noncross-validated r(2), and partial least squares (PLS) analysis results were used to predict the biological activity of 11 newly designed test set compounds. The best CoMFA model produced a q(2) of 0.815 and an r(2) of 0.976 indicating high statistical significance as a predictive model. The steric and electrostatic contributions from the contour map were interpreted from the color-coded contour plots generated from the PLS model and the active structural components for potency against C. neoformans were determined and validated in the test set compounds. The 3-substituted benzylthio quinolinium salts (4) that make up the test set were synthesized and evaluated based on the predicted activity from the CoMFA model and the results produced a good correlation between the predicted and experimental activity (R = 0.82). Thus, CoMFA has served as an effective tool to aid the design of new analogs and in this case, it has aided the identification of compounds equipotent with amphotericin B, the gold standard in antifungal drug design.
