  Novel thiazolones as HCV NS5B polymerase allosteric inhibitors: Further designs, SAR, and X-ray complex structure

  摘要：

  Structure-activity relationships (SAR) of 1 against HCV NS5B polymerase were described. SAR explorations and further structure-based design led to the identifications of 2 and 3 as novel HCV NS5B inhibitors. X-ray structure of 3 in complex with NS5B polymerase was obtained at a resolution of 2.2A, and confirmed the design.

NS5B is a critical enzyme for the replication of HCV RNA and is an interesting target for the screening and design of small molecule inhibitors to interfere in the HCV viral replication.

  背景：丙型肝炎病毒（HCV）感染是导致肝硬化和肝细胞癌导致肝衰竭的原因之一。估计世界人口中有2-3％的人长期感染HCV。HCV是编码单个多肽的阳性单链RNA病毒，可裂解为结构蛋白和非结构蛋白。非结构（NS）蛋白在病毒复制中起关键作用，并已成为HCV化疗的靶标。当前的治疗涉及基于聚乙二醇化干扰素-α/利巴韦林的治疗以及直接作用抗病毒药的组合。NS5B是复制HCV RNA的关键酶，并且是筛选和设计干扰HCV病毒复制的小分子抑制剂的有趣目标。 方法：在复制子测定中筛选化合物库，噻唑酮衍生物被鉴定为NS5B酶抑制剂（IC50：11 µM）。基于该先导化合物的结构，很少采用基于片段的方法设计和合成化合物的库。在设计新型化合物时，考虑了基于肽和基于非肽的蛋白酶抑制剂（如洛匹那韦和替普那韦）的结构特征。 结果：根据洛匹那韦和替普那韦的结构片段设计合成了几种新型蛋白酶抑制剂。这导致鉴定出具有噻唑酮骨架的化合物具有良好的抗HCV

  Quinazoline skeletons are synthesized by amino acid catabolism/reconstruction combined with the insertion/cyclization of dimethyl sulfoxide for the first time. The amino acid acts as a carbon and nitrogen source through HI-mediated catabolism and is then reconstructed using aromatic amines and dimethyl sulfoxide (DMSO) as a one-carbon synthon. This protocol is of great significance for the further

The series III analogues, which excluded the hydroxymethyl group and replaced the oxodithioacetal moiety of sparsomycin with a benzyl amide group, were designed to investigate the potential interaction of an amide oxygen in contrast to the sulfoxide oxygen of sparsomycin. Overall, the bromobenzyl-substituted analogues imparted the greatest inhibitory

  制备了三个系列的稀霉素类似物，并检查了它们在骨髓，P388淋巴细胞性白血病和P815肥大细胞瘤细胞中抑制DNA或蛋白质合成的能力。以包含或排除羟甲基官能团为特征的系列I和II化合物被设计为阐明对用4个取代的苄基取代sparsomycin的oxodithioacetal侧链的活性的影响。III系列类似物排除了羟甲基基团，并用苄基酰胺基团取代了Sparsomycin的氧二硫缩醛部分，旨在研究与Sparsomycin的亚砜氧相反的酰胺氧的潜在相互作用。总体而言，溴苄基取代的类似物在蛋白质合成分析中具有最大的抑制活性，而甲氧基苄基取代的类似物显示最少。甲基苄基化合物和未取代的苄基化合物在抑制潜力方面处于中间地位。蛋白质合成测定中的活性可以对应于类似物的苄基部分上的取代基的亲脂性和电子特性。所有化合物在DNA合成测定中均无活性。
