A series of substituted chromone-2-carboxylic acids was synthesized and tested as antagonists of SRS-A induced contractions of isolated guinea pig ileum. This work led to the discovery of sodium 7-[3-(4-acetyl-3hydroxy-2-propylphenoxy)-2-hydroxypropoxy]-4-oxo-8-propyl-4H-1-benzopyran-2-carboxylate (FPL 55712) which is the first reported specific antagonist of SRS-A. Some structural requirements for
合成了一系列取代的色酮-2-羧酸,并作为SRS-A诱导的豚鼠回肠收缩收缩的拮抗剂进行了测试。这项工作导致发现7- [3-(4-乙酰基-3-羟基-2-丙基苯氧基)-2-羟基丙氧基] -4-氧代-8-丙基-4H-1-苯并吡喃-2-羧酸钠(FPL 55712 ),这是第一个报道的SRS-A特异性拮抗剂。讨论了该系列生物活性的一些结构要求。
