Abstract5-Aminopyrido[3′,2′:4,5]thieno[3,2-c]isoquinolines were synthesized via alkylation of 3-cyanopyridine-2(1H)-thiones with 2-(chloromethyl)benzonitrile followed by treatment of the products with potassium tert-butoxide. The oxidation of the alkylated products to corresponding sulfoxides or sulfones followed by treatment with potassium tert-butoxide provided the corresponding 11-oxides or 11,11-dioxides
摘要 5-氨基吡啶并[3',2':4,5]噻吩并[3,2-c]异喹啉是通过3-氰基吡啶-2(1H)-硫酮与2-(氯甲基)苄腈的烷基化反应合成的。与叔丁醇钾的产物。烷基化产物氧化成相应的亚砜或砜,然后用叔丁醇钾处理,得到相应的11-氧化物或11,11-二氧化物。

Current treatment for hepatitis C is barely satisfactory, there is an urgent need to develop novel agents for combating hepatitis C virus infection. This study discovered a new class of thieno[ 2,3-b] pyridine derivatives as HCV inhibitors. First, a hit compound characterized by a thienopyridine core was identified in a cell-based screening of our privileged small molecule library. And then, structure activity relationship study of the hit compound led to the discovery of several potent compounds without obvious cytotoxicity in vitro (12c, EC50 = 3.3 mu M, SI > 30.3, 12b, EC50 = 3.5 mu M, SI > 28.6, 10l, EC50 = 3.9 mu M, SI > 25.6, 12o, EC50 = 4.5 mu M, SI > 22.2, respectively). Although the mechanism of them had not been clearly elucidated, our preliminary optimization of this class of compounds had provided us a start point to develop new anti-HCV agents.
