IC50 & Target
IC50: 117 nM (phosphodiesterase III)[1]
In Vitro
Siguazodan selectively inhibits the major cyclic AMP-hydrolysing PDE in human platelet supernatants. The inhibited enzyme has been variously termed cyclic GMP-inhibited PDE or PDE-III. In platelet-rich plasma (PRP), Siguazodan inhibits U46619-induced aggregation more potently than that induced by adenosine 5'-diphosphate (ADP), and collagen. Treatment of the PRP with Aspirin has no effect on the potency of Siguazodan. In washed platelets, Siguazodan increases cyclic AMP levels and reduces cytoplasmic free calcium. ADP decreases the ability of Siguazodan to raise cyclic AMP and this may explain its lower potency in inhibiting responses to ADP. Siguazodan has anti-platelet actions over the same concentration range that it is an inotrope and vasodilator[2].
