Trequinsin is a phosphodiesterase (PDE) 3 inhibitor that is dependent on cyclic AMP (cAMP), with IC50 values of 0.04 and 0.03 nM for PDE3A and PDE3B, respectively, in T84 human colonic adenocarcinoma cell lysates.{39526} In cultured primary rat juxtaglomerular cells, trequinsin stimulates cAMP accumulation when used at a concentration of 10 µM and increases cell membrane capacitance in a patch clamp assay.{39523} Trequinsin also competitively inhibits the multidrug resistant protein 5-mediated export of cGMP from Chinese hamster lung fibroblasts with a Ki value of 240 nM.{39524} In vivo, trequinsin reduces collagen-induced platelet aggregation in rabbits when administered intravenously at a rate of 3 µg/kg per minute, as well as the collagen-induced decrease in mean arterial blood pressure when administered alone or in combination with prostacyclin.{39522}
