[Problem] To provide a compound which may be used in treating diseases in which a calcium sensing receptor (CaSR) is concerned, particularly hyperparathyroidism.
[Means for Resolution] It was found that novel pyrrolidine derivatives which are characterized by the possession of aminomethyl group substituted with arylalkyl group or the like, or salts thereof, have excellent CaSR agonistic regulatory activity and also have excellent selectivity with CYP2D6 inhibitory activity having a possibility of causing drug interaction. Based on the above, these novel pyrrolidine derivatives are useful as therapeutic agents for treating diseases in which CaSR is concerned (hyperparathyroidism, renal osteodystrophy, hypercalcemia and the like).
[问题]提供一种可用于治疗钙传感受体(CaSR)相关疾病,特别是甲状旁腺机能亢进症的化合物。
[解决方法] 研究发现,新型吡咯烷衍生物(其特征在于具有被芳基烷基或类似基团取代的氨甲基)或其盐具有优异的 CaSR 激动调节活性,同时还具有优异的选择性和 CYP2D6 抑制活性,但有可能引起药物相互作用。基于以上所述,这些新型吡咯烷衍生物可作为治疗剂用于治疗与 CaSR 有关的疾病(甲状旁腺机能亢进症、肾性骨营养不良症、高钙血症等)。
