To discover an orally active thromboxane A(2) (TXA(2)) and leukotriene D(4) (LTD(4)) dual antagonist, we designed and synthesized chloroquinolylvinyl derivatives based on the structures of the TXA(2) antagonist daltroban and the LTD(4) antagonist montelukast. Among these derivatives, 4-[(2-(4-chlorophenylsulfonylamino)-1-3-[(E)-2-(7-chloro-2-quinolyl)vinyl]phenyl}ethyl)thio]methyl}benzoic acid (18d)
要发现口服活性血栓烷A(2)(TXA(2))和白三烯D(4)(LTD(4))双重拮抗剂,我们设计和合成了基于TXA(2)拮抗剂daltroban和LTD(4)拮抗剂孟鲁司特。在这些衍生物中,4-[((2-(4-氯苯基磺酰基氨基)-1-] [3-[(E)-2-(7-氯-2-喹啉基)乙烯基]苯基}乙基)硫基]甲基}苯甲酸(18d)显示了对豚鼠回肠中U46619诱导的豚鼠血小板聚集和LTD(4)诱导的收缩的有效抑制活性,IC(50)值分别为340 nm和0.40 nm。口服18天还抑制了LTD(4)诱导的豚鼠皮肤渗漏加速以及U46619诱导的豚鼠气道阻力增加,ED(50)值为0.47 mg / kg和3.3 mg / kg。
