Compounds useful as preventive and therapeutic agents for bone and cartilage diseases; and drug compositions containing the same. The compounds are polyhydroxyphenol derivatives of general formula (I)
and quinione analogues derived therefrom (wherein R1 is alkyl, optionally substituted benzyl or optionally substituted aryl; R2 is hydrogen, alkyl, alkenyl or optionally substituted benzyl; R3 is hydrogen, alkyl, alkenyl, optionally substituted benzyl, hydroxyl, alkoxy, alkenyloxy or optionally substituted benzyloxy; R4 is hydrogen, alkyl, alkenyl, optionally substituted benzyl or hydroxyl; and R5 and R6 are each independently hydrogen, alkyl, alkenyl or optionally substituted benzyl). The polyhydroxyphenol derivatives and the quinone analogues exhibit a potent inhibitory activity against bone resorption and are useful as preventive and therapeutic agents for bone and cartilage diseases.
有用于骨骼和软骨疾病的预防和治疗剂的化合物;以及包含这些化合物的药物组合物。这些化合物是一般式(I)的多羟基苯酚衍生物和由此衍生的醌类似物(其中R1是烷基,可选择取代苯甲基或可选择取代芳基;R2是氢,烷基,烯基或可选择取代苯甲基;R3是氢,烷基,烯基,可选择取代苯甲基,羟基,烷氧基,烯氧基或可选择取代苯甲氧基;R4是氢,烷基,烯基,可选择取代苯甲基或羟基;R5和R6各自独立地是氢,烷基,烯基或可选择取代苯甲基)。多羟基苯酚衍生物和醌类似物表现出强大的抑制骨吸收的活性,并且非常适用于骨骼和软骨疾病的预防和治疗剂。
