    摘要: The compound of the formula: ##STR1## positioned so that the gem-diphosphonic acid carbon atom is in the 4- or 5-position; R.sup.1 is alkyl or arylalkyl; R.sup.2 is hydrogen, 2- or 3-pyridinyl or 3-,5- or 6-alkylpyridin-2-yl; or a pharmaceutically acceptable salt thereof, with the proviso that when the gem-bisphosphonic acid substituted carbon atom is in 4-position, R.sup.1 is other than alkyl, used in the treatment of disease states involving calcium metabolism.
