The LIBRA compound library is a collection of 522 non-commercial molecules contributed by various Italian academic laboratories. These compounds have been designed and synthesized during different medicinal chemistry programs and are hosted by the Italian Institute of Technology. We report the screening of the LIBRA compound library against Trypanosoma brucei and Leishmania major pteridine reductase
LIBRA化合物库是由意大利各个学术实验室提供的522个非商业分子的集合。这些化合物是在不同的药物化学程序中设计和合成的,由意大利技术学院托管。我们报告了针对布鲁氏锥虫和利什曼原虫主要蝶啶还原酶1,TbPTR1和LmPTR1的LIBRA化合物库的筛选。九种化合物具有抗寄生虫PTR1的活性,并被选作基于细胞的寄生虫筛查剂,作为单药和与甲氨蝶呤(MTX)组合使用。鉴定出的最有趣的TbPTR1抑制剂是4-(苄氧基)嘧啶-2,6-二胺(LIB_66)。随后,合成了六种新的LIB_66衍生物以探索其结构-活性-关系(SAR)以及吸收,分布,代谢,排泄和毒性(ADMET)特性。结果表明,PTR1倾向于结合抑制剂,类似于其生物蝶呤/叶酸底物,例如2,4-二氨基嘧啶衍生物。
