We report design of a series of 2,4-diamino triazines as Mycobacterium tuberculosis (Mtb) dihydrofolate reductase inhibitors. The synthesized compounds were evaluated against Mtb (H37Rv and Dormant stage H37Ra), their cytotoxicity was assessed (HepG2 and A549 cell lines), and selectivity toward Mtb was evaluated by testing against other bacterial strains. Some derivatives showed promising activity
我们报告设计2,4-二氨基三嗪系列作为结核分枝杆菌(Mtb)二氢叶酸还原酶抑制剂的设计。评估合成的化合物对Mtb的抵抗力(H37Rv和Dormant阶段H37Ra),评估其细胞毒性(HepG2和A549细胞系),并通过针对其他细菌菌株进行测试来评估对Mtb的选择性。一些衍生物显示出有希望的活性以及低细胞毒性。全细胞分析中最有效的化合物(针对H37Rv的MIC为0.325μM)在酶分析中显示出选择性,并且与二线抗结核病药物对氨基水杨酸具有协同作用。因此,这项研究为抗结核DHFR抑制剂的进一步开发提供了有希望的分子。
