This paper reports on the synthesis and pharmacological activity of 6-aryl-4,5-dihydro-3(2H)-pyridazinone derivatives. The compounds exhibit an aggregation inhibiting action on human platelets in vitro and on rat platelets under ex vivo conditions, as well as a hypotensive action on rats. The strongest pharmacological effects were found with dihydropyridazinones, which have a 6-[p-[(chloroalkanoyl)amino]phenyl]
本文报道了6-芳基-4,5-二氢-3(2H)-哒嗪酮衍生物的合成及其药理活性。所述化合物在体外和在离体条件下对人血小板表现出对人血小板的聚集抑制作用,以及对大鼠的降血压作用。发现具有6- [对-[((氯代烷酰基)氨基]苯基]取代基以及在5-位具有甲基的二氢哒嗪酮具有最强的药理作用。这种类型的化合物在体外的抗聚集活性是乙酰水杨酸的高达16000倍,离体的抗聚集活性高达370倍。降压作用是比较物质二肼苯哒嗪的40倍。
