The compounds are polyhydroxyphenol derivatives of general formula (I) and quinone analogues derivative therefrom <CHEM> (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 quinone analogues exhibit a potent inhibitory activity against bone resorption and are useful as preventive and therapeutic agents for bone and cartilage deseases. |
