known inhibitor (1R,3R,4R)-1,3,4-trihydroxycyclohex-5-en-1-carboxylic acid are reported. These compounds were found to be reversible competitive inhibitors against Mycobacterium tuberculosis type II dehydroquinase, the third enzyme of the shikimic acid pathway. The most potent inhibitor, the 3-nitrophenyl derivative, has a K(i) of 54 nM, over 180 times more potent than the reported inhibitor (1R,3R
据报道,通过铃木(Suzuki)交联合成了已知抑制剂(1R,3R,4R)-1,3,4-三羟基环己基-5-en-1-羧酸的12个5-芳基类似物。发现这些化合物是针对结核分枝杆菌II型脱氢喹啉酶(the草酸途径的第三种酶)的可逆竞争性抑制剂。最有效的抑制剂3-硝基苯基衍生物的K(i)为54 nM,比已报道的抑制剂(1R,3R,4R)-5-氟-1,3,4-三羟基环己基-强180倍以上5-en-1-羧酸,比底物的K(M)低700倍以上,是已知的最有效的II型脱氢喹啉酶抑制剂。使用GOLD(2.2版)进行的对接研究表明,芳环与Arg19之间存在关键的静电结合相互作用,
