摘要

The insulinotropic action of the meglitinide analogues KAD-1229, A-4166 and repaglinide was examined in rat pancreatic islets deprived of exogenous nutrient or incubated in the presence of nutrient secretagogues such as D-glucose and the methyl esters of pyruvic acid, succinic acid and glutamic acid. The meglitinide analogues exerted little effect on insulin release in the absence of exogenous nutrient or in the presence of methyl pyruvate. They caused obvious stimulation of insulin output in the presence of D-glucose, dimethyl succinate or dimethyl glutamate. It is proposed, therefore, that suitable esters of dicarboxylic nutrients could be used to potentiate the secretory response to meglitinide analogues in non-insulin-dependent diabetes mellitus.
