Potent inhibitors for macrophomate synthase, which has recently been found to catalyze a highly unusual five-step chemical transformation, were explored. Among 11 oxalacetate analogs tested, only three analogs had moderate to relatively strong inhibitory activities (I50 1.3-8.1 mM). On the other hand, among 35 bicyclic intermediate analogs synthesized, two diacids were found to be the most potent inhibitors
探索了强膦酸酯合酶的有效抑制剂,最近发现它可以催化高度不同寻常的五步化学转化。在测试的11种草酰乙酸类似物中,只有3种类似物具有中等至相对较强的抑制活性(I50 1.3-8.1 mM)。另一方面,在35个合成的双环中间体类似物中,发现两种二酸是最有效的抑制剂(I50 0.80,0.84 mM),其亲和力比天然底物2-吡喃酮高得多。二酸的(-)-对映异构体显示的活性(I50为0.34,0.41 mM)是(+)-对映体的30倍。I50 / Km值(0.20,0.24)显示出有效的抑制作用。在两种代表性抑制剂中观察到竞争性抑制。
