As a result of an effort made by us for the purpose of developing a therapeutic agent having a bone formation-stimulating effect by promoting the functions of osteoblasts, the present inventors discovered that a certain nitrogen-containing heterocyclic compound exhibits a potent bone formation-stimulating effect on the osteoblast and thus can serve as an excellent prophylactic or therapeutic agent against a metabolic bone disease, whereby establishing the present invention.
Thus, the present invention provides a 3,6-disubstituted 1,2,4-triazolo[4,3-b]pyridazine compound or a pharmaceutically acceptable salt thereof as well as a pharmaceutical composition comprising such a compound and a pharmaceutically acceptable carrier, especially a bone-forming agent.
由于我们努力开发一种通过促进成骨细胞的功能而具有刺激骨形成作用的治疗剂,本发明人发现某种含氮杂环化合物对成骨细胞具有强效的骨形成刺激作用,因此可作为代谢性骨病的一种极好的预防或治疗剂,从而确立了本发明。
因此,本发明提供了一种3,6-二取代的1,2,4-三唑并[4,3-b]哒嗪化合物或其药学上可接受的盐,以及包含这种化合物和药学上可接受的载体,特别是骨形成剂的药物组合物。
