Described are new agents for treating bone disorders associated with a reduction in bone mass and abnormalities in bone resportion or bone formation including osteoporosis. Paget's disease, bone metastases and malignant hypercalcemia. The agents are hydroxyl containing steroidal hormones, having bone resportion antagonist or bone formation stimulatory activity, covalently linked through the hydroxyl group via a bond hydrolyzable in the human body, e.g. carbamate or carbonate, which is further covalently linked to an amino, or hydroxy substituted alkylidene-1,1-bisphosphonate, through the respective amino or hydroxy group. The alkyl bisphosphonate moiety confers bone affinity. The agent acts by delivering the steroidal hormone directly to the bone target site where it is released for bone resorption antagonist or bone formation stimulatory action by hydrolysis of the hydrolyzable covalent bond.
描述了用于治疗与骨量减少和骨重吸收或骨形成异常相关的骨疾病的新药物,包括骨质疏松症、帕盖特病、骨转移和恶性高钙血症。这些药物是含有羟基的类固醇激素,具有骨重吸收拮抗剂或骨形成刺激活性,通过在人体内可水解的键(如氨基甲酸酯或碳酸酯)通过羟基团共价连接,进一步通过相应的氨基或羟基团与氨基或羟基取代的烷基亚甲基-1,1-双膦酸酯共价连接。烷基双膦酸酯基团赋予药物骨亲和性。该药物通过将类固醇激素直接输送到骨靶位点,释放以通过水解可水解的共价键进行骨重吸收拮抗或骨形成刺激作用。
