  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.

  New series of 3-phenylquinoxaline 1,4-di-N-oxide with selective activity against Mycobacterium tuberculosis have been prepared and evaluated. Thirty-four of the seventy tested compounds showed an MIC value less than 0.2 mu g/mL, a value on the order of the MIC of rifampicin. Furthermore, 45% of the evaluated derivatives showed a good in vitro activity/toxicity ratio. The most active and selective compounds carry a fluorine atom in the quinoxaline 7-position or in the phenyl substituent para-position. In conclusion, the potency, low cytotoxicity and selectivity of these compounds make them valid lead compounds for synthesizing new analogues, particularly compound 7-methyl-3-(4'-fluoro) phenylquinoxaline-2-carbonitrile 1,4-di-N-oxide (MIC <0.2 mu g/mL and SI > 500).
