An anthranilic acid derivative represented by the general formula (X) [wherein R1 represents hydrogen or a carboxy-protecting group; R2 represents optionally substituted phenyl, a heterocyclic group, etc.; R3 represents optionally substituted phenyl, a monocyclic heterocyclic group, etc.; X1 represents carbonyl, etc.; X2 represents optionally substituted alkylene group, a bond, etc.; X3 represents oxygen, a bond, etc.; and X4 represents a group represented by the general formula —X5—X6— or —X6—X5— (wherein X5 means oxygen, a bond, etc.; and X6 means optionally substituted alkylene, a bond, etc.)] or a salt of the derivative. The derivative or salt has the inhibitory activity of MMP-13 production and is hence useful as a therapeutic agent for articular rheumatism, osteoarthritis, cancer, etc.
一种由通式(X)表示的蒽酸衍生物[其中R1表示氢原子或羧基保护基;R2表示可选取代的苯基,杂环基等;R3表示可选取代的苯基,单环杂环基等;X1表示羰基等;X2表示可选取代的烷基,键等;X3表示氧原子,键等;X4表示由通式-X5-X6-或-X6-X5-表示的基团(其中X5表示氧原子,键等;X6表示可选取代的烷基,键等)]或其盐。该衍生物或盐具有MMP-13生产的抑制活性,因此可用作治疗关节风湿病、骨关节炎、癌症等的治疗剂。
