series of peptides that contain an N-terminal 2-methyl-1,4-naphthoquinone group or analogues of this structure have been prepared as potential substrates or inhibitors of the rat liver microsomal vitamin K dependent carboxylase. The parent compound, gamma-2-(methyl-1,4-naphthoquinonyl-3)butyryl-Glu-Glu-Leu-OMe, is a good substrate for the carboxylase at low concentrations and has a Km of about 50 microM
已经制备了一系列含有N-末端2-甲基-1,4-萘醌基团的肽或具有这种结构的类似物作为大鼠肝脏微粒体维生素K依赖性羧化酶的潜在底物或抑制剂。母体化合物gamma-2-(甲基-1,4-萘醌基-3)丁酰基-Glu-Glu-Leu-OMe是低浓度羧化酶的良好底物,Km约为50 microM。这比已经合成的大多数简单肽底物的Km低大约2个数量级。用其去甲基类似物,萘基或硬脂基取代2-甲基-1,4-萘醌基会降低底物的有效性。在较高浓度下,母体化合物及其去甲基类似物是维生素K依赖性羧化反应的有效抑制剂。
