Derivatives of isatoic anhydride were prepared and tested as inhibitors of serine proteases. A number of isatoic anhydrides with positively charged substituents irreversibly inactivated several trypsin-like enzymes and preferentially inactivated trypsin over chymotrypsin. Further selectivity was obtained by introduction of an aromatic group on the N-1 position of isatoic anhydride. 7-(Aminomethyl)-1-benzylisatoic
制备了花生酸酐的衍生物,并测试了其为丝氨酸蛋白酶的抑制剂。与带胰凝乳蛋白酶的胰蛋白酶相比,许多带有正电荷取代基的等位酸酐不可逆地使几种胰蛋白酶样酶失活,并且使胰蛋白酶失活。通过在等酸酐的N-1位上引入芳族基团可以进一步提高选择性。制备了7-(氨基甲基)-1-苄基乙酸酐,它是凝血酶的选择性灭活剂。因此,有可能制备具有高酶选择性而不附接肽识别结构的等角酸酐的衍生物。
