    摘要: Novel pharmacologically active methylenebisphosphonates having formula (I) wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 independently are straight or branched, optionally unsaturated C.sub.1 -C.sub.10 -alkyl, optionally unsaturated C.sub.3 -C.sub.10 -cycloalkyl, aryl, aralkyl, silyl SiR.sub.3 or hydrogen, whereby in formula (I) at least one of the groups R.sup.1, R.sup.2, R.sup.3 or R.sup.4 is hydrogen and at least one of the groups is different from hydrogen, Q.sup.1 is hydrogen, hydroxyl, halogen, amino NH.sub.2, or OR', wherein R' is C.sub.1 -C.sub.4 -lower alkyl or acyl, Q.sup.2 is straight or branched, optionally unsaturated C.sub.1 -C.sub.10 -alkyl, -hydroxyalkyl or -aminoalkyl, whereby the oxygen may, as a substituent, contain one group or the nitrogen as a substituent may contain one or two groups, which are C.sub.1 -C.sub.4 -lower alkyl or acyl, or the two substituents of the nitrogen form together with the nitrogen atom a saturated, partly saturated or an aromatic heterocyclic ring, or Q.sup.2 is optionally substituted and optionally unsaturated C.sub.3 - C.sub.10 -cycloalkyl, which optionally is bound to the molecule over a straight or branched alkylene group containing 1-4 C-atoms, including the stereoisomers, such as the geometrical isomers and the optically active isomers, of the compounds, as well as the pharmacologically acceptable salts of these compounds. ##STR1##
