  • Patent number: 8377923
    Abstract: [Problem] A compound, which can be used for preventing or treating diseases, in which 11?-hydroxysteroid dehydrogenase type 1 (11?-HSD1) is concerned, in particular, diabetes, insulin resistance, dementia, schizophrenia and depression, is provided. [Means for Solution] It was found that a triazole derivative, in which one of the 3- and 5-positions of the triazole ring has (di)alkylmethyl or cycloalkyl, each of which is substituted with —O— (aryl or a heterocyclic group, each of which may be substituted, or lower alkylene-cycloalkyl), and the other thereof has aryl, a heterocyclic group or cycloalkyl, each of which may be substituted, or a pharmaceutically acceptable salt thereof exhibits potent 11?-HSD1 inhibitory action. From the above, the triazole derivative of the present invention can be used for preventing or treating diabetes, insulin resistance, dementia, schizophrenia and depression.

  • Patent number: 8207199
    Abstract: A compound which is useful as an active ingredient of a pharmaceutical composition for treating neuropathic pain is provided. The present inventors have made extensive studies on compounds having an FAAH inhibitory activity, and as a result, have found that an azole compound substituted with an N-(pyridine-3-yl)oxycarbonyl-piperidin-4-yl group and a phenyl group or a pharmaceutically acceptable salt thereof has an excellent FAAH inhibitory activity, thereby completing the present invention. The compound of the present invention is confirmed to have an excellent FAAH inhibitory activity and an antiallodynic effect in rat models with neuropathic pain, and thus is useful as an agent for preventing and/or an agent for treating neuropathic pain.

  • Patent number: 8106190
    Abstract: To provide a novel and excellent agent for treating or preventing nociceptive pain, neuropathic pain, cancer pain, headache, bladder function disorder and the like, based on the inhibitory action on the capsaicin receptor VR1 activation. The present invention was accomplished by confirming that a benzamide derivative characterized by the possession of a benzene ring in which a single ring is condensed on the nitrogen atom of amido group and possession of a lower alkylamino or an amino group substituted with a ring group at the neighboring position of said amido group has a strong inhibitory action on VR1 activation and excellent pharmacological actions based on this and by finding that it can become an excellent agent for treating or preventing VR1-involved diseases such as nociceptive pain, neuropathic pain, cancer pain, headache, bladder function disorder and the like.

  • Publication number: 20110212973
    Abstract: [Problems] A compound useful as an active ingredient for a pharmaceutical composition for treating FAAH-related diseases is provided. [Means for Solution] The present inventors have made extensive studies on compounds having an FAAH inhibitory activity, and as a result, have found that a piperazine-1-carboxylate compound, in which benzimidazol-2-ylcarbonyl, benzofuran-2-ylcarbonyl or the like binds to the 4-position of the piperazine, has an excellent FAAH inhibitory activity and further has an action to increase the effective bladder capacity, an action to ameliorate sleep disorders, an anti-diuretic action, and an analgesic activity on lower urinary tract pain including bladder pain and the like, thereby completed the present invention.
