摘要:
The synthesis and structural characterization of a series of 1,1-dinitroethyl substituted furoxans are described. Their vasodilatory properties, evaluated on isolated rings of rabbit thoracic aorta precontracted with noradrenaline, as well as their ability to inhibit the collagen induced aggregation in human platelet-rich plasma, are reported. The most active derivative of the series is 3-(1,1-dinitroethyl)-4-phenylfuroxan 7b. Its vasodilatory property is similar to that of glyceryl trinitrate. In addition, this compound is a more potent platelet aggregation inhibitor than sodium nitroprusside.
