Fused heterocyclic amido compounds as anti-hepatitis C virus agents
摘要:
We identified a fused heteroaromatic amido structure based on the phenanthridine skeleton as a superior scaffold for candidate drugs with potent anti-HCV activity. Among the compounds synthesized, a phenanthridine analogue with a 1,3-dioxolyl group (24) possessed the most potent anti-HCV activity (EC50 value: 50 nM), with acceptable cytotoxicity. The structural development and structure-activity relationships of these compounds are described. (C) 2011 Elsevier Ltd. All rights reserved.
This invention provides a therapeutic agent for hepatitis C comprising, as an active ingredient, a compound having anti-HCV activity useful in treatment of hepatitis C. The therapeutic agent for hepatitis C comprises, as an active ingredient, a compound represented by formula (I) or a pharmaceutically acceptable salt thereof.

General Method for the Amination of Aryl Halides with Primary and Secondary Alkyl Amines via Nickel Photocatalysis
the coupling of electron-rich and electron-poor aryl halides with both primary and secondary alkyl amines. In this study, it is reported that a Ni(II)-bipyridine complex catalyzes efficient C–N coupling of aryl chlorides and bromides with various primary and secondary alkyl amines under direct excitation with light. Intramolecular C–N coupling is also demonstrated. The feasibility and applicability of
