An anthranilic acid derivative represented by the general formula (X) [wherein R
1
represents hydrogen or a carboxy-protecting group; R
2
represents optionally substituted phenyl, a heterocyclic group, etc.; R
3
represents optionally substituted phenyl, a monocyclic heterocyclic group, etc.; X
1
represents carbonyl, etc.; X
2
represents optionally substituted alkylene group, a bond, etc.; X
3
represents oxygen, a bond, etc.; and X
4
represents a group represented by the general formula -X
5
-X
6
- or -X
6
-X
5
- (wherein X
5
means oxygen, a bond, etc.; and X
6
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的抑制活性,因此可用作关节风湿病,骨关节炎,癌症等的治疗剂。
