A benzophenone derivative represented by the following formula:
wherein
R
1
represents, for example, an optionally substituted heterocyclic group, or a substituted phenyl group; Z represents, for example, an alkylene group; R
2
represents, for example, a carboxyl group optionally protected with alkyl;
R
3
represents, for example, an optionally protected hydroxyl group; R
4
represents, for example, an optionally substituted cycloalkyloxy group; and R
5
represents, for example, a hydrogen atom, or a salt thereof has anti-arthritic activity, inhibits bone destruction caused by arthritis, and provides high safety and excellent pharmacokinetics and thus is useful as therapeutic agent for arthritis. These compounds have inhibitory effect on AP-1 activity and are useful as preventive or therapeutic agent for diseases in which excessive expression of AP-1 is involved.
以下是一种苯甲酮衍生物的化学式:
其中,R1代表例如可选取代的杂环基团或取代的苯基团;Z代表例如烷基链;R2代表例如可用烷基保护的羧基;R3代表例如可选保护的羟基;R4代表例如可选取代的环烷氧基团;R5代表例如氢原子或其盐。该化合物具有抗关节炎活性,能抑制由关节炎引起的骨破坏,并提供高安全性和优异的药代动力学,因此可用作治疗关节炎的药物。这些化合物具有抑制AP-1活性的作用,可用作预防或治疗与过度表达AP-1有关的疾病的药物。
