The present invention produces alkyldiphosphonic acid derivative of the general formula: ##STR1## wherein Het is a heteroaromatic five-membered ring containing to 3 heteroatoms which can be partly hydrogenated and optionally substituted one or more times by alkyl, alkoxy, phenyl, cyclohexyl, cyclohexylmethyl, halogen or amino, and two adjacent alkyl substituents can together also form a ring, Y is a hydrogen atom or a lower alkyl radical, X is a hydrogen atom, a hydroxyl group or an amino group optionally substituted by lower alkyl and R is a hydrogen atom or a lower alkyl radical, with the proviso that Het is not a pyrazole ring; as well as the pharmacologically acceptable salts thereof. The present invention also provides processes for the prepearation of these compounds and pharmaceutical compositions containing them useful for the treatment or prophylaxis of calcium metabolism disturbances or disease as for example osteoporosis, Bechterew's disease, bone metastases, urolithiasis, heterotropic ossifications, rheumatoid arthritis osteoarthritis or degenerative arthrosis.
本发明生产一般式为:##STR1##的烷基二膦酸衍生物,其中Het是一种杂环芳香五元环,包含1至3个杂原子,可以部分氢化,并且可以被烷基,烷氧基,苯基,环己基,环己基甲基,卤素或氨基取代一次或多次,两个相邻的烷基取代基也可以共同形成一个环,Y是氢原子或较低的烷基基团,X是氢原子,羟基或氨基,可以被较低的烷基取代,R是氢原子或较低的烷基基团,但Het不是吡唑环;以及其药理学上可接受的盐。本发明还提供了制备这些化合物的方法以及包含它们的制药组合物,用于治疗或预防钙代谢障碍或疾病,例如骨质疏松症,Bechterew病,骨转移,泌尿结石,异位成骨,类风湿性关节炎,骨关节炎或退行性骨关节炎。
