A series of substituted 5-benzyl-3-(1-carboxy-2-phenylethyl)hydantoins was prepared by condensation of aromatic aldehydes with the corresponding 5-unsubstituted hydantoin followed by reduction of the intermediate benzylidene derivative. The compounds were assessed as inhibitors of dihydro-orotate dehydrogenase from Clostridium oroticum. It was found that hydrophobic and electron-donating substituents
通过芳族醛与相应的5-未取代的乙内酰脲缩合,然后还原中间体亚苄基衍生物,制备一系列取代的5-苄基-3-(1-羧基-2-苯基乙基)乙内酰脲。所述化合物被评估为来自梭状芽胞杆菌的二氢乳清酸酯脱氢酶的抑制剂。发现苄基的苯环中的疏水和供电子取代基有利于结合和不可逆的抑制。该系列的结果与标准取代基参数相关,由此推导了抑制机理。这涉及在C-5对乙内酰脲进行快速去质子化,然后确定氢化物或其等同物的去除率。
