Indole-carboxylic acid compounds of the formula: ##STR1## wherein R.sub.1 is lower alkyl or alkoxy radical or halogen; R.sub.2 is halogen; lower alkyl or alkoxy radical; or R.sub.1 and R.sub.2 can together also form an alkylene bridge containing 3 to 5 carbon atoms, which can optionally contain one or more double bonds; and, but less preferably, when R.sub.1 is a lower alkyl or alkoxy radical, R.sub.2 can also be a hydrogen atom, and physiologically compatible salts and esters thereof, Are outstandingly effective as blood sugar-lowering agents.
式为:##STR1##其中R.sub.1是较低的烷基或烷氧基或卤素基;R.sub.2是卤素;较低的烷基或烷氧基;或者R.sub.1和R.sub.2也可以形成含有3到5个碳原子的烷基桥,该烷基桥可以选择性地含有一个或多个双键;但较不理想的是,当R.sub.1是较低的烷基或烷氧基时,R.sub.2也可以是氢原子,以及其生理兼容的盐和酯,作为降低血糖剂具有卓越的效果。
