摘要:
The present inventors achieved the present invention on the basis of the knowledge that a thiazole derivative with a pyrazine-2-carbonylamine substituent at the second carbon position is an excellent positive allosteric modulator of the muscarinic M3 receptor and is useful as a prophylactic and/or therapeutic agent against bladder/urinary tract disorders associated with bladder contractions induced by the muscarinic M3 receptor. A 2-acylaminothiazole derivative or a salt thereof according to the present invention can be used as a prophylactic and/or therapeutic agent against bladder/urinary tract disorders associated with bladder contractions induced by the muscarinic M3 receptor, including, for example, urinary disorders such as underactive bladder. (In the formula, R1 is -(N(-R11)(-R12) or an optionally substituted cyclic amine; R11 is a C1–6 alkyl; R12 is an optionally substituted C1–6 alkyl or an optionally substituted C3–8 cycloalkyl; R2 is an optionally substituted aryl, an optionally substituted monocyclic aromatic heterocycle, or an optionally substituted bicyclic aromatic heterocycle; and R3 is -H,-OH, -O-( C1–6 alkyl), or a halogen.).Problema Se proporciona un compuesto que es de utilidad como un ingrediente activo de una composición farmacéutica para el tratamiento de disfunciones de almacenamiento, disfunciones de evacuación y enfermedades del tracto urinario inferior. [Medios de solución] Los presentes inventores hallaron que un derivado de tiazol con pirazin-2-carbonilamino sustituido en la posición 2 es un excelente modulador alostérico positivo del receptor muscarínico M3 y es de utilidad como un agente para prevenir y/o tratar enfermedades de la vejiga o del tracto urinario, relacionadas con la contracción de la vejiga por el receptor muscarínico M3, completando así la presente invención. El derivado de 2-acilaminotiazol o una de sus sales de la presente invención se puede usar como un agente para prevenir y/o tratar enfermedades de la vejig
