  Novel spirosuccinimides with incorporated isoindolone and benzisothiazole 1,1-dioxide moieties as aldose reductase inhibitors and antihyperglycemic agents

  摘要：

  Compounds from two novel series of spirosuccinimides were prepared. Analogs of series 2 possessed a spiro-fused isoindolone moiety while those of series 3 contained a spiro-fused benzisothiazole S,S-dioxide group. These compounds were evaluated as aldose reductase inhibitors (ARI) in vitro by their ability to inhibit glyceraldehyde reduction using a partially purified bovine lens aldose reductase preparation and in vivo as inhibitors of galactitol accumulation in the lens, sciatic nerve, and diaphragm of galactose-fed rats. Many members from the isoindolone series 2, particularly those containing an isoindolone N-methyl moiety, showed good in vitro and in vivo potency. The most potent member, the 6-chloro analog 32, was resolved, and aldose reductase activity was found to reside almost exclusively in the (+)-enantiomer. Compound 32 was approximately equipotent in the sciatic nerve of the galactose-fed rat to other cyclic imide ARI's of similar in vitro activity, namely sorbinil and ADN-138 and also to tolrestat, an acetic acid-based ARI (ED50's 4-8 mg/kg). Compounds from both series, 2 and 3, were also found to lower plasma glucose levels of genetically obese db/db and ob/ob mice with potency similar to that of ciglitazone. However, members from these series failed to lower insulin levels of the ob/ob mouse at the doses tested.

  基于糖精和乙酰磺胺的碳酸酐酶抑制剂的新颖见解：设计，合成，模型研究和生物活性评估

  摘要：

  摘要 已经合成了糖精和乙酰磺胺酸衍生物的大型文库，并针对人碳酸酐酶的四种同工型，两种脱靶的hCA I / II和与肿瘤相关的同工型hCA IX / XII进行了评估。糖精和乙酰磺胺酸核心都尝试了不同的支架修饰策略，从而获得了60种化合物。它们中的一些表现出在纳摩尔范围内的抑制活性，尽管某些进行的改变导致针对hCA IX / XII的微摩尔活性或不存在。分子模型研究将注意力集中在这些化合物与酶的结合方式上。拟议的抑制机制是锚定在锌结合的水分子上。对接研究以及分子动力学也强调了化合物灵活性的重要性（例如，

  herein a catalyst‐free visible‐light photolytic protocol for the imidation of arenes and heteroarenes. N‐Bromosaccharin was identified as a viable and chemoselective nitrogen radical precursor that undergoes controllable homolytic cleavage under ambient light irradiation. The reaction can be applied to a number of arenes and heteroarenes with good chemo‐ and regioselectivity. Mechanistic studies revealed
