  • Title: Effect of methoxyindole 2-carboxylic acid and 4-pentenoic acid on adipose tissue metabolism.
    Author: Gorin E, Zendowski S.
    Journal: Biochim Biophys Acta; 1975 May 22; 388(2):268-78. PubMed ID: 1138899.
    Abstract:
    1. Administration of methoxyindole 2-carboxylic acid to rats caused an increase in circulating free fatty acids which was associated with rapid hypoglycemia in fasted rats and liver glycogenolysis without hypoglycemia in fed rats. 2. The incorporation of labeled glucose, pyruvate and acetate carbons into triacylglycerol-glycerol, triacylglycerol-fatty acids and CO2 was inhibited in epididymal fat pads from methoxyindole 2-carboxylic acid-treated rats and by the addition of methoxyindole 2-carboxylic acid in vitro. In contrast, palmitate esterification and oxidation were enhanced by methoxyindole 2-carboxylic acid. 3. The activity of enzymes associated with fatty acid synthesis was reduced to a varying degree in the presence of methoxyindole 2-carboxylic acid in the reaction mixture in concentrations lower than those used to inhibit glucose and pyruvate metabolism in the intact tissue in vitro. 4. 4-Pentenoic acid, a potent inhibitor of pyruvate and palmitate metabolism in the liver, was considerably less effective in adipose tissue. 5. The effect of the two hypoglycemic substances investigated on adipose tissue metabolism seems to be different.
