Imidazole derivatives substituted in the 1-position by a carboxyalkyl group or an ester of a such and the acid addition salts thereof, and where possible the alkali metal and alkaline earth metal salts thereof possess good antiphlogistic and analgesic activities. Such compounds are prepared, for example, by introducing the carboxyalkyl group or an ester of a such into the 1-position of a corresponding imidazole derivative unsubstituted in the 1-position. Alternatively such compounds are prepared by reacting an appropriate keto-oxime with an appropriate amino compound and an appropriate aldehyde or acetal and optionally reducing the imidazole derivative thus obtained.
在1位点上被羧基烷基或其酯基取代的咪唑衍生物及其酸加成盐,如可能,其碱金属和碱土金属盐具有良好的抗炎和镇痛活性。例如,通过将羧基烷基或其酯基引入未在1位点上取代的相应咪唑衍生物的1位点中来制备这样的化合物。或者,通过将适当的酮肟与适当的氨基化合物和适当的醛或缩醛反应,并可选地还原得到的咪唑衍生物来制备这样的化合物。
