New and known analogues of 2, 2'-dithiodibenzamide were synthesized and tested for various pharmacological actions. This series of compounds was found to inhibit collagen-and adenosine 5'-diphosphate-induced aggregations of blood platelets. 2, 2'-Dithiobis (N-(2-hydroxypropyl) benzamide) (3, KF4939) was one of the most potent compounds in in vitro aggregometry studies. Compound 3 after oral administration also potently inhibited pulmonary thrombosis induced by arachidonic acid injection in mice and platelet aggregation ex vivo in rats. This compound may have clinical value as a new orally active inhibitor of platelet aggregation.
新合成了已知的2,2'-二硫代二苯甲酰胺类似物,并测试了它们的多种药理作用。发现这一系列化合物能抑制胶原和5'-二磷酸腺苷诱导的血小板聚集。2,2'-二硫代双(N-(2-羟丙基)苯甲酰胺)(3,KF4939)是在体外聚集实验中活性最强的化合物之一。3号化合物经口服给药后,也能强效抑制小鼠由花生四烯酸注射引起的肺血栓形成和大鼠离体血小板聚集。该化合物可能具有临床价值,是一种新型口服活性血小板聚集抑制剂。
