2-phenyl-3-(pyridin-4-yl)imidazo[1,2-a]pyrazines and the 3-iodo precursors, bearing a polar moiety at the C-8 position, was synthesized and evaluated for their antileishmanial activities. Two derivatives exhibited very good activity against the promastigote and the amastigote forms of Leishmania major in the micromolar to submicromolar ranges, coupled with a low cytotoxicity against macrophages and
合成了一系列原始的2-苯基-3-(吡啶-4-基)咪唑并[1,2-a]吡嗪和3-碘前体,它们在C-8位置带有一个极性部分,并对其进行了评估。狂欢活动。在微摩尔至亚微摩尔范围内,两种衍生物对利什曼原虫的前鞭毛体和鞭毛体形式表现出非常好的活性,并且对巨噬细胞和3T3小鼠成纤维细胞的细胞毒性较低。通过LmCK1抑制测定,将讨论对这些有前途的抗疟原虫化合物的假定分子靶标的研究。
