A series of 1-substituted and 4-substituted benzyl analogues of the known inhibitor (1S,3R,4R)-1,3,4-trihydroxy-5-cyclohexene-1-carboxylic acid has been synthesized and tested as inhibitors of Streptomyces coelicolor type II dehydroquinase. The solid-phase syntheses of 18 new analogues are reported. The most potent inhibitor, 2-nitrobenzyloxy analogue 5i, has K(i) of 8 microM, more than 30 times lower
合成了一系列已知抑制剂(1S,3R,4R)-1,3,4-三羟基-5-环己烯-1-羧酸的1-取代和4-取代的苄基类似物,并已作为coelicolor链霉菌的抑制剂进行了测试。 II型脱氢喹啉酶。报道了18种新类似物的固相合成。最有效的抑制剂2-硝基苄氧基类似物5i的K(i)为8 microM,比底物的K(M)低30倍以上,而其效力比原始抑制剂高约4倍。通过与GOLD 2.0的分子对接研究了合成类似物在活性位点的结合模式。
