The present invention relates to novel heterocycle-substituted diphosphonic acids, and the pharmaceutically-acceptable salts and esters thereof, in which the diphosphonate-substituted carbon atom moiety is attached to a carbon atom in a nitrogen-containing six membered ring heterocycle, preferably a piperidine ring. The heterocycle-substituted diphosphonic acid compounds have the general structure:
wherein Z is a nitrogen-containing six membered ring heterocycle moiety selected from piperidinyl, diazinyl and triazinyl; m, n and m+n are from about 0 to about 10; Q is a covalent bond or a moiety selected from oxygen, sulfur or nitrogen; and R¹, R², and R³ are substituent groups.
The present invention further relates to pharmaceutical compositions containing these novel compounds. Finally, this invention relates to methods for treating or preventing diseases characterized by abnormal calcium and phosphate metabolism by utilizing a compound or pharmaceutical composition of the present invention.
本发明涉及新型杂环取代的二膦酸及其药学上可接受的盐和酯,其中二膦酸取代的碳原子分子连接到含氮六元环杂环,最好是哌啶环中的碳原子上。杂环取代的二膦酸化合物具有一般结构:
其中 Z 是选自哌啶基、重氮基和三嗪基的含氮六员环杂环分子;m、n 和 m+n 是约 0 至约 10;Q 是共价键或选自氧、硫或氮的分子;R¹、R² 和 R³ 是取代基。
本发明还涉及含有这些新型化合物的药物组合物。最后,本发明涉及利用本发明的化合物或药物组合物治疗或预防以钙和磷酸盐代谢异常为特征的疾病的方法。
