Abstract：
:G619, a 4-OH-isophthalic acid derivative, was studied for its capacity to inhibit platelet aggregation. G619 dose-dependently inhibited U46619, collagen, ADP, PAF, thrombin and epinephrine-induced platelet aggregation in vitro. The IC50 values for inhibition of U46619-induced human and rabbit platelet aggregation were 39 and 43 microM, respectively. G619, at 100 microM, inhibited high concentration collagen (10 micrograms/ml)-induced aggregation of rabbit platelets pretreated with indomethacin and increased the level of cAMP in washed rabbit platelets by 30% (p less than 0.01 vs basal). However, G619, did not inhibit fibrinogen binding to GPIIb/IIIa receptor, phosphodiesterase, U46619-induced contractile responses on canine saphenous vein or rabbit aorta, calcium-induced vasoconstriction and thrombin or PAF-induced elevation of [Ca++]i in platelets in vitro. In vivo, the U46619-induced maximal thrombocytopenia in rats was reduced from 40% (vehicle) to 22% and 18% by 10 and 30 mg/kg of G619 i.v., respectively. G619 (30 mg/kg) had no effect on the U46619-induced vasopressor response or sudden death in rats, and had no effect on TxB2 formation. Our results indicate that G619 is a broad-spectrum platelet aggregation inhibitor and may have its effect on a common mechanism for platelet aggregation besides an effect on the thromboxane A2 receptor.
