Benzamide derivatives of the formula: ##STR1## wherein R.sub.1 is a hydrogen atom, a methyl group or a methoxy group; R.sub.2 is a straight-chain or branched-chain alkyl group having 2 to 8 carbon atoms, a substituted phenyl group, or group --NHR.sub.4, R.sub.4 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; R.sub.3 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 have the action to reduce the blood glucose level and, therefore, are useful as medicines.
苯甲酰胺衍生物的化学式为:##STR1## 其中 R.sub.1 是氢原子、甲基基团或甲氧基;R.sub.2 是具有2至8个碳原子的直链或支链烷基基团、取代苯基团,或基团--NHR.sub.4,其中 R.sub.4 是氢原子、具有1至6个碳原子的直链或支链或环烷基基团,或可能在核上有取代基的苯基团;R.sub.3 是氢原子或具有1至4个碳原子的一或两个烷基基团,n 为0或1,提供了制备这些衍生物的方法,以及含有这些衍生物的药物组合物。上述化学式的化合物具有降低血糖水平的作用,因此可用作药物。
