The present invention concerns novel disphosphonates having the general formula I ##STR1## in which Het represents a heterocyclic five-membered ring with 2-4 heteroatoms which is substituted, if desired, and which can also be partially hydrogenated, R.sub.1 -R.sub.7 each denote, independently of each other, hydrogen or C.sub.1 -C.sub.5 alkyl, X=denotes hydrogen, OH or the group --NR.sub.8 R.sub.9, in which R.sub.8 and R.sub.9 should each be, independently of each other, hydrogen or C.sub.1 -C.sub.5 alkyl, m and n denote, independently of each other, 0, 1 or 2, as well as their pharmacologically safe salts and optically active forms.
本发明涉及具有一般式I的新型二磷酸酯化合物
其中Het代表带有2-4个杂原子的杂环五元环,如有需要,可以取代,并且也可以是部分氢化的,R.sub.1 -R.sub.7各自独立地表示氢或C.sub.1 -C.sub.5烷基,X=表示氢、OH或基团--NR.sub.8 R.sub.9,其中R.sub.8和R.sub.9各自独立地表示氢或C.sub.1 -C.sub.5烷基,m和n各自独立地表示0、1或2,以及它们的药理学安全盐和光学活性形式。
