2-Alkoxy-2-propenylidene methanaminiums inhibited gluconeogenesis and stimulated glycolysis by hepatocytes isolated from 48-h-fasted rats and fasted-refed rats, respectively. The order of effectiveness of these compounds was the same as the hypoglycemic response of intact rats found in other studies, i.e., butoxy greater than propoxy greater than ethoxy derivative. Lactate/pyruvate and beta-hydroxybutyrate/acetoacetate ratios were elevated whereas cellular ATP concentration was decreased by these compounds. The butoxy derivative inhibited the oxidation of [U-14C]glucose to 14CO2 but increased glucose utilization and lactate accumulation by isolated rat diaphragms. The butoxy derivative also inhibited site I reversed electron transfer and the oxidation of NAD+-linked substrates but not succinate by isolated rat liver mitochondria. Methanaminium-induced hypoglycemia in intact rats was accompanied by an increase in blood lactate concentration as well as blood beta-hydroxybutyrate to acetoacetate ratio. The hypoglycemia caused by these compounds is proposed to be due to inhibition of glucose synthesis in the liver along with increased glucose utilization in peripheral tissues, both for want of ATP as a consequence of inhibition of site I electron transfer.
