and evaluated as inhibitors of rat liver catechol O-methyltransferase. The compounds exhibited either noncompetitive or competitive patterns of inhibition when 3,4-dihydroxybenzoic acid was the variable substrate. The benzaldehydes were significantly more potent inhibitors than the corresponding benzoic acids, and electron-withdrawing substituents in the 5 position greatly enhanced their inhibitory
已经合成了一系列5-取代的3-羟基-4-甲氧基苯甲酸(异香草酸)和-苯甲醛(异香草醛),并将其作为大鼠肝儿茶酚O-甲基转移酶的抑制剂。当3,4-二羟基苯甲酸是可变底物时,化合物表现出非竞争性或竞争性抑制作用。苯甲醛是比相应的苯甲酸明显更有效的抑制剂,并且5位的吸电子取代基大大提高了它们的抑制活性。
