(E)-2-Acetyl-4-(2-diethylcarbamoyl-1-methylvinyl)-7-(1-phenylethoxy)benzo[b]furan (4b) with a characteristic conformation and (E)-2-(2-morpholinocarbo-1-methylvinyl)-7-ethoxycarbopropoxybenzo[b]furan ((E)-3b) were prepared and evaluated for their leukotriene B4
(LTB4) antagonistic activity. Compound 4b showed potent antagonistic activity against human BLT1 and BLT2 receptors. Compound (E)-3b displayed selective BLT2 receptor antagonistic activity. Both compounds were inactive to cysteinyl LT receptors.

二乙基氨基甲酰基-1-甲基
乙烯基)-7-(1-苯乙氧基)苯并[b]
呋喃(4b)和(E)-2-(2-吗啉基羰基-1-甲基
乙烯基)-7-乙氧基羰基
丙氧基苯并[b]
呋喃((E)-3b),并评估了它们对
白三烯B4(LTB4)的拮抗活性。化合物4b对人类BLT1和BLT2受体显示出有效的拮抗活性。化合物(E)-3b显示出选择性BLT2受体拮抗活性。两种化合物对半胱
氨酰LT受体均无活性。
