on 2‐pyrazyl and 2‐pyridylhydrazone derivatives. The compounds were tested against the promastigotes of Leishmania amazonensis and L. braziliensis, murine macrophages, and intracellular L. amazonensis amastigotes. The most potent antileishmanial compound was selected for investigation into its mechanism of action. Among the evaluated compounds, five derivatives [(E)‐3‐((2‐(pyridin‐2‐yl)hydrazono)methyl)benzene‐1
在这项工作中,我们报告了23种基于2-吡唑基和2-吡啶基hydr衍生物的化合物的抗衰老活性。该化合物对的前鞭毛体进行测试利什曼亚马孙和L. braziliensis,小鼠巨噬细胞,和细胞内亚马逊利什曼原虫无鞭毛体。选择了最有效的抗衰老化合物来研究其作用机理。在评估的化合物中,有五种衍生物[[ E)-3-((2-(吡啶-2-基)肼基)甲基)苯-1,2-二醇(2 b),(E)-4-((2 -(吡啶-2-基)肼基)甲基)苯-1,3-二醇(2 c),(E)-4-硝基-2-((2-(吡嗪-2-基)肼基)甲基)苯酚(2 s),(E)-2-(2-(吡啶-2-基亚甲基)肼基)吡嗪(2 u)和(E)-2-(2-(((5-硝基呋喃-2-基)亚甲基)肼基)吡嗪(2 v)]表现出显着的活性,以抵制亚马逊L. amaztigote形式,IC 50值低于20μm。大多数化合物对鼠巨噬细胞没有显示任何毒性作用。对该肼衍
