  • Patent number: 8163746
    Abstract: Provided is an agent for treating or preventing urinary frequency, urinary urgency and urinary, incontinence which are associated with overactive bladder, a lower urinary tract disease such as interstitial cystitis and chronic prostatitis accompanied by lower urinary tract pain, and various diseases accompanied by pain. A novel azolecarboxamide derivative in which an azole ring such as thioazole or oxazole is bonded to a benzene ring, pyridine ring or pyrimidine ring through carboxamide was confirmed to have a potent trkA receptor-inhibitory activity and found to be an agent for treating or preventing lower urinary tract disease and various diseases accompanied by pain, which is excellent in efficacy and safety, and thus the present invention was accomplished.

  • Patent number: 7960562
    Abstract: It is intended to provide a compound useful as a GnRH receptor antagonist. The inventors further investigated propane-1,3-dione derivatives. As a result, they confirmed that a compound having a benzene ring or a thiophene ring substituted with a group represented by —SO2—R3 in a propane-1,3-dione derivative having 2-(1,3-dihydro-2H-benzimidazol-2-ylidene) has an excellent GnRH receptor antagonistic effect and accomplished the present invention. Because the compound of the present invention has a potent GnRH receptor antagonistic effect, it is useful for the treatment of sex hormone-dependent diseases, particularly GnRH-related diseases. Further, because the compound of the present invention has an excellent metabolic stability in human and few drug interactions, therefore it has preferable characteristics as a pharmaceutical used for the above-mentioned diseases.

  • Patent number: 7585886
    Abstract: [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).
