[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).

It comprises compounds which are derived from a drug or a substance with therapeutic properties, and useful as reagents for the synthesis of biostable polymers including said drug in their backbone, namely polyurethanes, polyureas or polyurea urethanes that are biocompatible and biostable. It also comprises the processes for preparing the compounds and the polymers, as well as to the use of these polymers for the manufacture of medical devices.
