Benzamide derivatives of the formula:
wherein R, is a hydrogen atom, a methyl group of a methoxy group; R2 is a straight-chain or branched-chain alkyl group having 2 to 8 carbon atoms, a substituted phenyl group, or group -NHR4, R4 being a hydrogen atom, a straight-chain or branched-chain or cyclic alkyl group having 1 to 6 carbon atoms, or a phenyl group that may have a substituent on the nucleus; R3 is a hydrogen atom or one or two alkyl groups having 1 to 4 carbon atoms and n is 0 or 1, a process for preparing these derivatives, and pharmaceutical compositions containing the same are provided.
The compounds of the above formula has the action to reduce the blood glucose level and, therefore, are useful as medicines.
式中的苯甲酰胺衍生物:
其中R,是氢原子、甲基或甲氧基;R2是具有2至8个碳原子的直链或支链烷基、取代的苯基或基团-NHR4,R4是氢原子、具有1至6个碳原子的直链或支链或环状烷基或在核上可能具有取代基的苯基;R3 是氢原子或一个或两个具有 1 至 4 个碳原子的烷基,n 是 0 或 1,提供了制备这些衍生物的工艺和含有这些衍生物的药物组合物。
上式化合物具有降低血糖水平的作用,因此可用作药物。
