  • Publication number: 20110172230
    Abstract: [Object] To provide a compound which can be used for the treatment of a disease associated with fatty acid amide hydrolase (FAAH), particularly urinary frequency, urinary incontinence and/or overactive bladder. [Means for solution] It is confirmed that a urea compound chemical-structurally characterized by having a piperidine or piperazine ring or a salt thereof has an excellent FAAH-inhibitory activity, and thus the present invention is completed. The urea compound or its pharmaceutically acceptable salt of the present invention can increase the effective bladder capacity and ameliorate the state of urinary frequency, and is therefore useful as an agent for treating urinary frequency, urinary incontinence and/or overactive bladder.

  • 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: 7919495
    Abstract: To provide a compound usable for treatment of diseases associated with fatty acid amide hydrolase (FAAH), especially for treatment of urinary frequency and urinary incontinence, overactive bladder and/or pain. We have found that a novel pyridyl non-aromatic nitrogen-containing heterocyclic-1-carboxylate derivative and its pharmaceutically acceptable salt has a potent FAAH-inhibitory activity. Further, the pyridyl non-aromatic nitrogen-containing heterocyclic-1-carboxylate derivative of the present invention has an excellent effect for increasing an effective bladder capacity, an excellent effect for relieving urinary frequency and an excellent anti-allodynia effect, and is therefore usable for treatment of urinary frequency and urinary incontinence, overactive bladder and/or pain.
