Hepatitis C virus (HCV) infection is a main cause of chronic liver disease, leading to liver cirrhosis and hepatocellular carcinoma (HCC). The objective of our research was to develop effective agents against viral replication. Here, we have synthesized a series of anilinoquinoline derivatives. Based on a cell-based HCV replicon system, we observed that 2-(3'-nitroanilino)quinoline (18) exhibited anti-HCV activity with a 50% effective concentration (EC50) value of 7 mu M and a selective index (SI) value of 10. In addition, compound 18 possessed the inhibitory effect on HCV NS3/4A protease activity. Therefore, we concluded that the compound 18 possessed a potent activity against HCV replication and could provide as a new lead compound as anti-HCV inhibitor. (C) 2011 Elsevier Ltd.

Microwave-assisted synthesis of quinoline, isoquinoline, quinoxaline and quinazoline derivatives as CB2 receptor agonists
Quinoline, isoquinoline, quinoxaline, and quinazoline derivatives were synthesized using microwave-assisted synthesis and their CB1/CB2 receptor activities were determined using the [35S]GTPγS binding assay. Most of the prepared quinoline, isoquinoline, and quinoxalinyl phenyl amines showed low-potency partial CB2 receptor agonists activity. The most potent CB2 ligand was the 4-morpholinylmethanone
使用微波辅助合成法合成喹啉,异喹啉,喹喔啉和喹唑啉衍生物,并使用[ 35 S]GTPγS结合测定法测定其CB1 / CB2受体活性。大部分制备的喹啉,异喹啉和喹喔啉基苯胺均显示出低效的部分CB2受体激动剂活性。最有效的CB2配体是4-吗啉基甲酮衍生物(化合物40e)(-log EC 50 = 7.8;E max = 75%)。异喹啉-1-基(3-三氟甲基-苯基)胺(化合物26c)是一种高效的CB2激动剂(-log EC 50 = 5.8; E max = 128%)。在这些研究中,没有发现明显的CB1受体激活或失活,除了40e表现出弱的CB1激动剂活性(CB1-log EC 50 = 5.0)。这些配体用作开发选择性CB2受体激动剂的新型模板。
