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 new and efficient synthesis of benzof'uro[3,2-b]quinolin-6(11H) one (3) is reported, by treatment of 2- [(phenoxy)acetyl]amino} benzoic acid (6a) with polyphosphoric acid. An intermediate in the conversion of 3 to 6a, namely, 2-(3-benzofuranylamino)benzoic acid (7), was defined. An improved method for the synthesis of 6a is also described, which was used to prepare analogs (6b-n) of 6a. In addition
报道了一种新的高效合成苯并f'uro [3,2 - b ]喹啉-6(11 H)的一(3)的方法,该方法是用2-[((苯氧基)乙酰基]氨基}苯甲酸(6a)处理多磷酸。定义了3至6a转化的中间体,即2-(3-苯并呋喃基氨基)苯甲酸(7)。用于合成的改进方法6a中还描述的,将其用于制备类似物(图6b-N的)6a中。另外,苯并呋喃[3,2-]的11-烷氧基衍生物(8)和11-二烷基氨基衍生物(10和11)。b ]喹啉由3制备。
