The synthesis and biological characterization of some 3-carboxylate isosteres of PAF-acether structurally modified in positions 1 (ether, carbamate), 2 (acetoyl, ethoxy), and 3 (chain length and polar head group) are reported. All derivatives present antagonist activities against PAF-acether-induced effects in vitro (platelet aggregation) and in vivo (bronchoconstriction and thrombocytopenia in guinea
报道了在位置1(醚,氨基甲酸酯),2(乙酰基,乙氧基)和3(链长和极性头基)上结构修饰的PAF-醚的一些3-羧酸酯等排体的合成和生物学特性。所有衍生物在体外(血小板聚集)和体内(豚鼠的支气管收缩和血小板减少,以及在大鼠中低血压程度较小)均表现出拮抗PAF-醚诱导的作用。此处介绍的功能修饰不会显着改变拮抗剂活性的效力,并且没有对映选择性。除1-氨基甲酰基类似物(对乙酰胆碱诱导的低血压和支气管收缩同样有效)外,所有等位基因都是特异性的PAF-醚拮抗剂。
