In an attempt to explore novel and more potent antileishmanial compounds to diversify the current inhibitors, we pursued a medicinal chemistry-driven strategy to synthesize novel scaffolds with common pharmacophoric features of dihydropyrimidine and chalcone as current investigational antileishmanial compounds. Based on the reported X-ray structure of Pteridine reductase 1 (PTR1) from Leishmania major
为了探索新型和更有效的抗风白蚁化合物以使目前的抑制剂多样化,我们采用了药物化学驱动的策略来合成具有二氢嘧啶和查耳酮的共同药理学特征的新型支架,作为目前研究的抗风白蚁化合物。基于报道的来自利什曼原虫(Leishmania major)的蝶啶还原酶1(PTR1)的X射线结构,我们设计了许多基于二氢嘧啶的衍生物,以在PTR1活性位点进行特异性相互作用。我们的先导化合物8i对L. Major和Leishmania donovani的前鞭毛体显示出有效的体外抗疟药活性,IC50值分别为0.47杯/毫升和1.5杯/毫升。出色的体外活性最终表明,我们的先导化合物足以根除内脏和局部利什曼病。此外,还进行了对接分析和计算机模拟ADMET。预测的分子特性支持了我们的实验分析,即这些化合物具有消除内脏和局部利什曼病的潜力。
