Thioacetates as precursors of thiols are interesting starting points for synthesizing other organosulfur compounds. Herein, we propose a simple, efficient and fast method to obtain organic thioacetates using water as a solvent. Taking into account the great attention that has been paid toward environmentally friendly synthetic procedures in the past decades, we prove the role and the strength of the

Synthesis and preliminary evaluation of the anti-cancer activity on A549 lung cancer cells of a series of unsaturated disulfides
We synthesized a series of small symmetrical unsaturated disulfides by a multi-step reaction starting from organic alcohols, and we performed a preliminary test to evaluate the effect of these compounds on the viability of A549 lung cancer cells. The garlic-derived natural compound diallyl disulfide, known for its anticancer activity, was used as the lead compound in this study. We synthesized five
The deleteriouseffect of ethylenegas on the ring‐closing olefinmetathesis (RCM) for the formation of 5‐ to 8‐membered rings was investigated. Significant rate differences caused by ethylenegas were observed among the different ring‐size formation reactions. Nevertheless, the rate differences can be advantageously utilized for chemoselective RCM.

makes it an appealing target for the potential development of new pain drugs. The utility of nonselective Nav blockers is often limited due to adverse cardiovascular and CNS side effects. We sought more selective Nav1.7 blockers with oral activity, improved selectivity, and good druglike properties. The work described herein focused on a series of 3- and 4-substituted indazoles.

Na v 1.7电压门控离子通道在疼痛信号传导途径中的作用的遗传验证使其成为潜在的新型止痛药开发目标。由于心血管和中枢神经系统的不良反应,非选择性Na v阻滞剂的应用常常受到限制。我们寻求具有口服活性,更高的选择性和良好的药物性质的更具选择性的Na v 1.7阻滞剂。本文所述的工作集中于一系列3-和4-取代的吲唑。3取代的吲唑的SAR研究得到了类似物7,其在体外和体内的活性良好,但在大鼠体内的药代动力学却很差。对4-取代的吲唑的优化产生了两种化合物27和48,具有良好的体外和体内活性,并具有改善的大鼠药代动力学特征。27和48在急性大鼠单碘乙酸盐诱发的骨关节炎模型的疼痛中均显示出强劲的活性,而48的亚慢性给药则显示在7天内向较低的EC 50转移。
