title: Anti-thrombotic effect of KC-404, a novel cerebral vasodilator.
abstract: KC-404 prevented mice from death and rats from A-V block, both induced by rapid i.v. injection of adenosine diphosphate (ADP), at high doses (5-100 mg/kg, i.v.). KC-404, at relatively lower doses (0.5-2 mg/kg, i.v.), inhibited the electroencephalographic (EEG) change in rat rapidly administered with arachidonic acid (AA) into the internal carotid artery. KC-404 (0.3-3 mg/kg, p.o.) inhibited the necrotic change of lower leg, paw or finger of rat when injected with sodium laurate into the femoral artery. KC-404 at doses up to 100 mg/kg, p.o. did not alter bleeding time in rat. Thus, KC-404 is expected to be of therapeutic value in cerebrovascular disorders accompanying thrombus in cerebral vasculature.
