Abstract

A study on the effect of anandamide (AEA) in energy coupling of rat liver mitochondria is presented. Micromolar concentrations of AEA, while almost ineffective on substrate supported oxygen consumption rate and on uncoupler stimulated respiration, strongly inhibited the respiratory state III. AEA did not change the rate and the extent of substrate generated membrane potential, but markedly delayed rebuilding by respiration of the potential collapsed by ADP addition. Overall, these data suggest that anandamide inhibits the oxidative phosphorylation process. Direct measurement of the F"oF"1 ATP synthase activity showed that the oligomycin sensitive ATP synthesis was inhibited by AEA, (IC"5"0, 2.5@mM), while the ATP hydrolase activity was unaffected. Consistently, AEA did not change the membrane potential generated by ATP hydrolysis.
