    • 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.
    • 本发明产生以下通式的烷基二膦酸衍生物:其中Het是含有3个杂原子的杂芳族五元环,其可以被部分氢化并任选地被烷基,烷氧基,苯基, 环己基,环己基甲基,卤素或氨基,两个相邻的烷基取代基可一起形成环,Y为氢原子或低级烷基,X为氢原子,羟基或任选被低级烷基取代的氨基, R是氢原子或低级烷基,条件是Het不是吡唑环; 以及其药理学上可接受的盐。 本发明还提供了这些化合物的预切方法和含有它们的药物组合物的方法,所述方法可用于治疗或预防钙代谢紊乱或疾病,例如骨质疏松症,Bechterew氏病,骨转移,尿石症,异质性骨化,类风湿性关节炎骨关节炎或退行性 关节。
