of a literature survey, structure-based virtual screening and synthesis of a small library was performed to identify hits to the potential antimycobacterial drug target, glutamine synthetase. The best inhibitor identified from the literature survey was (2S,5R)-2,6-diamino-5-hydroxyhexanoic acid (4, IC(50) of 610+/-15microM). In the virtual screening 46,400 compounds were docked and subjected to a pharmacophore
进行文献调查,基于结构的虚拟筛选和小文库合成的组合,以鉴定对潜在的抗分枝杆菌药物靶标谷氨酰胺合成酶的命中。从文献调查中确定的最佳抑制剂是(2S,5R)-2,6-二氨基-5-羟基己酸(4,IC(50)610 +/- 15microM)。在虚拟筛选中,对接了46,400种化合物,并进行了药效团搜索。在这些化合物中,购买了29种并在生物学分析中进行了测试,从而可以鉴定出三种含有芳香族支架的新型抑制剂。基于虚拟筛选的命中结果之一,合成了一个由15个类似物组成的小型文库,产生了四种抑制谷氨酰胺合成酶的化合物。
