The invention concerns known and novel compounds which fall under the general formula:
wherein A encompasses a wide range of values including but not limited to aryl, loweralkyl, cycloalkyl, and carbohydrates including sucrose and fructose; p is equal to the number of hydroxy groups on A and may be zero; z is the number of -OS(O)2NR1R2 groups and is always at least one; R1 and R2 are selected from hydrogen, loweralkyl, carboxy and the like; which compounds are useful for treating chronic arthritis and osteoporosis. A novel process for preparing the compounds is provided wherein an appropriate sulfamic acid aryl ester is reacted with a a hydroxy substituted A radical which may or may not contain thereon protected carboxyl, amino or hydroxy substituents, in an aprotic solvent containing a tertiary amine base. Pharmaceutical compositions for the treatment of chronic arthritis and osteoporosis are also provided.
本发明涉及属于通式的已知和新型化合物:
其中,A 的数值范围很广,包括但不限于芳基、低级烷基、环烷基以及包括蔗糖和果糖在内的碳水化合物;p 等于 A 上羟基的数目,可以是零;z 是 -OS(O)2NR1R2 基团的数目,总是至少一个;R1 和 R2 选自氢、低级烷基、羧基等;这些化合物可用于治疗慢性关节炎和骨质疏松症。本发明提供了一种制备这些化合物的新工艺,即在含有叔胺基的钝溶剂中,将适当的氨基磺酸芳基酯与羟基取代的 A 基反应,A 基上可以含有或不含有受保护的羧基、氨基或羟基取代基。此外,还提供了用于治疗慢性关节炎和骨质疏松症的药物组合物。
