[Problems] To provide a pharmaceutical, in particular a compound which can be used as a therapeutic agent for irritable bowel syndrome (IBS).[Means for Solving Problems] It was found that a tetrahydroisoquinolin-1-one derivative having an amide group at the 4-position or a pharmaceutically acceptable salt thereof has an excellent bombesin 2 (BB2) receptor antagonistic action. It is also found that the tetrahydroisoquinolin-1-one derivative is highly effective on bowel movement disorders. From the above, the tetrahydroisoquinolin-1-one derivative of the present invention is useful as a therapeutic agent for diseases associated with a BB2 receptor, in particular IBS.

Pyrimidine-5-carboxamide derivatives represented by a general formula (I) or salts thereof [wherein each symbol has the following meaning; X: O, S, NR1, CO, NR1CO, CONR1, C═N—OR1 or a bond, Y: a lower alkylene group which may be substituted by OR1 or —NHR1, or a bond, Z: O, NR2 or a bond, A: H, or a lower alkyl which may have a substituent, a —CO-lower alkyl which may have a substituent, an aryl which may have a substituent, a heteroaryl which may have a substituent, a cycloalkyl which may have a substituent or a nitrogen-containing saturated heterocyclic group which may have a substituent, B: an aryl which may have a substituent or a heteroaryl group which may have a substituent, R1, R2: H, a lower alkyl or a —CO-lower alkyl group].
摘要:
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.
摘要:
There is provided medicaments, particularly a vascular endothelial growth factor (VEGF) inhibitor which is useful as a therapeutic drug for solid tumors, diabetic retinopathy and the like diseases in which angiogenesis is taking a role. That is, since a novel 3-quinolin-2(1H)-ylideneindolin-2-one derivative or a salt thereof has good VEGF inhibitory action, angiogenesis inhibitory action and anti-tumor action, it is useful as ideal VEGF inhibitor, angiogenesis inhibitor and anti-tumor agent.
