  Structure–activity relationship studies of 1-(4-chloro-2,5-dimethoxyphenyl)-3-(3-propoxypropyl)thiourea, a non-nucleoside reverse transcriptase inhibitor of human immunodeficiency virus type-1

  摘要：

  The reverse transcriptase (RT) of the human immunodeficiency virus type-1 (HIV-1) is still a prime target for drug development due to the continuing need to block drug-resistant RT mutants by new inhibitors. We have previously identified 1-(4-chloro-2,5-dimethoxyphenyl)-3-(3-propoxypropyl)thiourea, compound 1, as a potent RI inhibitor from an available chemical library. Here, we further modified this compound to study structure activity relationships when replacing various groups in the molecule. Different functional groups were systematically introduced on the aromatic ring and the aliphatic chain of the compound was modified. The effect of these modifications on viral infectivity was then evaluated. The most potent compound found was propyl 4-(amino-N-(4-chloro-2,5-dimethoxyphenyl)methanethioamino)butanoate, 45c, which inhibited infectivity with a calculated IC50 of about 1.1 mu M. Docking studies identified potential important interactions between the top scoring ligands and HIV-1 RT, and the predicted relative affinity of the ligands was found to be in agreement with the experimental results.

  神经元一氧化氮合酶的血红素协调抑制剂。疏水接触可稳定铁-硫醚配位，而不会增加抑制剂效力

  摘要：

  血红素-硫醚配体相互作用通常发生在血红素铁和天然蛋氨酸配体之间，但由于难以稳定 Fe-S 键，基于硫醚的血红素配位（II 型）抑制剂并不常见。在这里，设计了一种基于硫醚的神经元一氧化氮合酶（nNOS）抑制剂（3），并通过分光光度法和晶体学对其结合进行了表征。获得了与血红素铁配位的抑制剂3的晶体结构，据我们所知，这代表了与任何血红素酶复合的硫醚抑制剂的第一个晶体结构。还评估了一系列相关的潜在抑制剂 (4-8)。化合物 4-8 均被发现是铁 nNOS 的 I 型（非血红素配位）抑制剂，但发现 4 和 6-8 在血红素还原为亚铁态时转变为 II 型，反映了硫醚的更高亲和力亚铁血红素比铁血红素。与人们普遍认为的相反，发现硫醚-血红素连接不会增加抑制剂的效力，这说明了硫醚-铁血红素连接的内在弱点。硫醚硫上烷基的细微变化引起了结合构象的剧烈变化，表明疏水接触在稳定硫醚-血红素配位中起着至关重要的作用。

  between heme iron and native methionine ligands, but thioether-based heme-coordinating (type II) inhibitors are uncommon due to the difficulty in stabilizing the Fe-S bond. Here, a thioether-based inhibitor (3) of neuronal nitric oxide synthase (nNOS) was designed, and its binding was characterized by spectrophotometry and crystallography. A crystal structure of inhibitor 3 coordinated to heme iron was obtained

• Pronounced Catalytic Effect of a Micellar Solution of Sodium Dodecyl Sulfate (SDS) on the Efficient C-S Bond Formation<i>via</i>an Odorless Thia-Michael Addition Reaction through the<i>in situ</i>Generation of<i>S</i>-Alkylisothiouronium Salts

  Abstractmagnified imageA pronounced catalytic effect of sodium dodecyl sulfate (SDS) was observed on thein situproduction ofS‐alkylisothiouronium saltsviathe reaction of primary, allyl and benzyl halides with thiourea in SDS droplets .Hydrolysis of the generatedS‐alkylisothiouronium salts in the palisade layer of the droplets produces the corresponding thiol moieties which are immediately added to the electron‐deficient olefins that are present in the micellar core to produce the thia‐Michael adducts. The entire route is an almost odorless process. The yields of the products are good to excellent and the method is applicable to large‐scale operation without any problem.
