2'-Substituted analogs of triclosan have been synthesized to target inhibition of the key malarial enzyme Plasmodium falciparum enoyl acyl carrier protein reductase (PfENR). Many of these compounds exhibit good potency (EC50<500 nM) against in vitro cultures of drug-resistant and drug-sensitive strains of the P. falciparum parasite and modest (IC50=1-20 microM) potency against purified PfENR enzyme
合成了2'-取代的三氯生类似物以靶向抑制关键的疟疾酶恶性疟原虫烯酰基酰基载体蛋白还原酶(PfENR)。这些化合物中的许多化合物对恶性疟原虫寄生虫的耐药菌株和药物敏感菌株的体外培养均显示出良好的效价(EC50 <500 nM),对纯化的PfENR酶具有适度(IC50 = 1-20 microM)的效价。与三氯生相比,本次2'-取代衍生物调查显示,其寄生虫的3D7和Dd2菌株分别获得了20倍和30倍以上的收益。
