In an effort to address potential cardiotoxicity liabilities identified with earlier frontrunner compounds, a number of new 3,5-diaryl-2-aminopyridine derivatives were synthesized. Several compounds exhibited potent antiplasmodial activity against both the multidrug resistant (K1) and sensitive (NF54) strains in the low nanomolar range. Some compounds displayed a significant reduction in potency in
为了解决由早期先驱化合物鉴定出的潜在心脏毒性问题,合成了许多新的3,5-二芳基-2-氨基吡啶衍生物。几种化合物对低纳摩尔范围内的耐多药(K1)和敏感(NF54)菌株均显示出有效的抗疟原虫活性。与先前报道的领先者类似物相比,某些化合物在hERG通道抑制试验中显示出显着的效力降低。这些新类似物中的几种在伯氏疟原虫小鼠模型中显示出有希望的体内功效,并将进一步评估为潜在的临床候选药物。描绘了体外抗血浆和hERG活性的SAR。
