Neglected diseases represent a major health problem. It is estimated that one third of the world population is infected with tuberculosis (TB). Besides TB, Chagas disease, affects approximately 20 million people. Quinoxalines display great activities against TB and Chagas. Forty new quinoxaline 1,4-di-N-oxide derivatives have been prepared and tested against M. tuberculosis and T. cruzi. Carboxylic acid quinoxaline 1,4-di-N-oxides (CAQDOs) 5 and 17 showed MIC values on the same order as the reference antituberculosis drug, rifampicin. Meanwhile, CAQDOs 12 and 22 presented IC50 values in the same order as the anti-chagasic drug, nifurtimox.
被忽视的疾病是一个重大的健康问题。据估计,全世界三分之一的人口感染了结核病(TB)。除肺结核外,南美锥虫病也影响着大约 2000 万人。喹喔啉类化合物对结核病和南美锥虫病有很强的抗病活性。现已制备出 40 种新的喹喔啉 1,4-di-N-oxide 衍生物,并对其进行了结核杆菌和南美锥虫病测试。羧酸喹喔啉 1,4-二-N-氧化物(CAQDOs)5 和 17 的 MIC 值与参考抗结核药物利福平的 MIC 值处于同一顺序。同时,CAQDOs 12 和 22 的 IC50 值与抗胆囊炎药物硝呋太尔制霉素的 IC50 值顺序相同。
