There are provided carbazate derivatives of the formula: R.sup.1 --N.dbd.CH--NHNH--R.sup.2 wherein R.sup.1 is a heterocyclic group; and R.sup.2 is an esterified carboxyl group, and their salts, which are useful as AGE-formation inhibitory agents. The derivatives or the salts can be produced by reacting compounds of the formula: R.sup.1 --N.dbd.CH--OR.sup.3 wherein R.sup.1 is a heterocyclic group; and R.sup.3 is a lower alkyl group, with a carbazic acid ester or its salt.
提供了公式为:R.sup.1 --N.dbd.CH--NHNH--R.sup.2的羧酸酯衍生物,其中R.sup.1是杂环基团;R.sup.2是酯化的羧基基团,以及它们的盐,可用作AGE形成抑制剂。该衍生物或其盐可通过将公式为:R.sup.1 --N.dbd.CH--OR.sup.3的化合物与羧肼酸酯或其盐反应而制得,其中R.sup.1是杂环基团;R.sup.3是较低的烷基基团。
