A series of potent anthranilic acid-based inhibitors of the hepatitisCNS5Bpolymerase has been identified. The inhibitors bind to a site on NS5B between the thumb and palm regions adjacent to the active site as determined by X-ray crystallography of the enzyme-inhibitor complex. Guided by both molecular modeling and traditional SAR, the enzyme activity of the initial hit was improved by approximately
已鉴定出一系列强效邻氨基苯甲酸丙型肝炎 NS5B 聚合酶抑制剂。通过酶抑制剂复合物的 X 射线晶体学测定,抑制剂与 NS5B 上拇指和手掌区域之间与活性位点相邻的位点结合。在分子建模和传统 SAR 的指导下,初始命中的酶活性提高了约 100 倍,产生了一系列有效且选择性的 NS5B 抑制剂,IC50 值低至 10 nM。这些化合物也是培养的 HUH7 细胞中 HCV 复制子的抑制剂。

A one-pot synthesis of anthranilates from acyclic unsaturated β-enamino esters with a catalytic amount of Pd(OAc)2 was achieved for the first time. The substrates for the key catalytic reaction were easily prepared from acetoacetate esters and amines, and functionalized anthranilates were obtained in moderate to good chemical yields. A simple assembly of a 13C-labeled anthranilate was demonstrated
