anti-trypanosomatidic agents. Molecular docking and crystallography guided the design and synthesis of 42 new benzothiazoles. The compounds were assessed for Trypanosoma brucei and Leishmania major PTR1 inhibition and in vitro activity against T. brucei and amastigote Leishmania infantum. We identified several 2-amino-benzo[ d]thiazoles with improved enzymatic activity ( TbPTR1 IC50 = 0.35 μM; LmPTR1
2-氨基苯并[d]噻唑被确定为开发改进的蝶啶还原酶-1(PTR1)抑制剂和抗锥虫病药物的新型支架。分子对接和晶体学指导了42种新型苯并噻唑的设计和合成。评估了这些化合物对布鲁氏锥虫和利什曼原虫的主要PTR1抑制作用以及对布鲁氏锥虫和鞭毛鞭毛体婴儿利什曼原虫的体外活性。我们确定了几种具有改善的酶促活性的2-氨基苯并[d]噻唑(TbPTR1 IC50 = 0.35μM; LmPTR1 IC50 = 1.9μM)和低的针对布鲁氏杆菌的抗寄生虫活性。十种对TbPTR1活性最高的化合物在联合抗布鲁氏杆菌时能增强甲氨蝶呤的抗寄生虫活性,增强指数在1.2到2.7之间。对该化合物文库进行了早期ADME毒性分析,最终确定了2-氨基-N-苄基苯并[d]噻唑-6-羧酰胺(4c)是一种新型有效,安全且选择性的抗胰锥oc剂(EC50 = 7.0μM )。用羟丙基-β-环糊精配制4c可产生良好的口服生物利用度,从而促进了体内研究的进展。
