  Synthesis and structure–activity relationship of 3-phenylquinoxaline 1,4-di-N-oxide derivatives as antimalarial agents

  摘要：

  As a continuation of our research and with the aim of obtaining new antimalarial agents, new series of 3-phenylquinoxaline 1,4-di-N-oxide derivatives have been synthesized following the classical Beirut reaction. Antiplasmodial activity was evaluated in vitro against Plasmodium falciparum by the incorporation of [H-3]-hypoxanthine. Cytotoxicity was tested in KB cells by AlamarBlue assay. Twenty-one of the 60 compounds that were assayed against 3D7 (CQ-sensitive) showed enough activity to be also evaluated against K1 (CQ-resistant) strain. Ten of them were shown to be more active than chloroquine in the resistant strain. The most interesting compounds are 7-(methyl or methoxy)-3-(4'-fluoro or chloro)phenylquinoxaline-2-carbonitrile 1,4-di-N-oxides because of their low IC50 and their high SI shown for the K1 strain, making them valid new leads.

  In a continuing effort to identify new active compounds for combating Chagas disease and other neglected diseases, our research group synthesized and evaluated 23 3-arylquinoxaline-2-carbonitrile di-N-oxides against Trypanosoma cruzi. Five of them presented IC50 values of the same magnitude as the standard drug Nifurtimox, making them valid as new lead compounds. The optimized molecular structures of 23 derivatives represented by 1497 types of DRAGON descriptors were subjected to linear regression analysis, and the derived QSAR was shown to be predictive. In this way, we achieved a rational guide for the proposal of new candidate structures whose activities still remain unknown. (C) 2010 Elsevier Ltd. All rights reserved.
