Synthesis and Dual Antagonistic Activity against Thromboxane A2 and Leukotriene D4 of (4-(1-(Benzenesulfonamido)alkyl)phenyl)alkanoic Acid Derivatives.
was examined. The results demonstrated that both 4-[4-[1-(4-chlorobenzenesulfonamido)hexyl]phenyl]butyricacid (12e) and 4-[4-[1-(4-chlorobenzenesulfonamido)-5-methylhexyl]phenyl]bu tyric acid (12m) possessed good anti-LTD4 activities. Compounds 12e and 12m were then evaluated for other related pharmacological effects involving the arachidonic acid cascade. These compounds appear to be hybrid eicosanoids
为了找到对血栓烷A2(TXA2)和白三烯D4(LTD4)受体具有双重拮抗活性的新型哮喘药,进行了各种[4- [1-(苯磺酰胺基)-烷基]苯基]链烷酸衍生物的合成和药理学评估。 。通过测量对L-46619诱导的豚鼠气管收缩以及LTD4诱导的豚鼠回肠和气管收缩的抑制作用来评估TXA2和LTD4的体外拮抗活性。几种化合物显示出令人满意的双重拮抗活性,并研究了它们对豚鼠体内LTD4诱导的支气管收缩的作用(口服后)。结果表明,4- [4- [1-(4-氯苯磺酰胺基)己基]苯基]丁酸(12e)和4- [4- [1-(4-氯苯磺酰胺基)-5-甲基己基]苯基] bu tyric酸(12m)具有良好的抗LTD4活性。然后评估化合物12e和12m涉及花生四烯酸级联反应的其他相关药理作用。这些化合物似乎是杂类类花生酸拮抗剂,具有对抗前列腺素D2(PGD2)和PGF2σ诱导的豚鼠气管收缩的拮抗活性,以及TXA2和LTD4拮抗活性。
