Aromatic analogues of chorismate were synthesised as potential inhibitors of anthranilate synthase. Molecular modelling using GOLD2.1 showed that these analogues docked into the active site of Serratia marcescens anthranilate synthase in the same conformation as chorismate. Most compounds were found to be micromolar inhibitors of S. marcescens anthranilate synthase. The most potent analogue, 3-(1-carboxy-ethoxy)-4-hydroxybenzoate (KI 3 µM), included a lactyl ether side chain. This appears to be a good replacement for the enol-pyruvyl side chain of chorismate.
作为潜在的邻氨基苯甲酸合酶抑制剂,合成了色氨酸合成前体色氨酸酸的芳香类似物。使用GOLD2.1进行的分子模拟显示,这些类似物以与色氨酸酸相同的构象结合到粘质沙雷氏菌的邻氨基苯甲酸合酶的活性部位。大多数化合物被发现是粘质沙雷氏菌邻氨基苯甲酸合酶的微摩尔级抑制剂。其中最有效的类似物是3-(1-羧基乙氧基)-4-羟基苯甲酸(KI 3 µM),它含有一个乳酸醚侧链,这似乎是色氨酸酸的烯醇吡啶基侧链的良好替代品。
