Based on the initial optimization of orally active antimalarial 2,4-diamino-thienopyrimidines and with the help of metabolite identification studies, a second generation of derivatives involving changes at the 2- and 4-positions of the thienopyrimidine core were synthesized. Improvements in the physiochemical properties resulted in the identification of 15a, 17a, 32, and 40 as lead molecules with improved
基于口服活性抗疟疾2,4-二氨基-噻吩并嘧啶类化合物的初步优化,并借助代谢物鉴定研究,合成了第二代涉及噻吩并嘧啶核苷2-位和4-位变化的衍生物。物理化学性质的改善导致鉴定出15a,17a,32和40为具有改善的体内暴露的铅分子。此外,当在伯氏疟原虫中每天一次以50 mg / kg的剂量口服4天时,类似物40表现出优异的体内抗疟活性。 小鼠模型,其活性优于先前报道的化合物,且hERG谱略有改善。
