toxicological effect in the form of peroxisomal proliferation was performed in order to achieve the target compound OT4003. OT4003 ((S)-(+)-E-2-(3-(2-(7- chloroquinolin-2-yl)ethenyl)phenylaminomethyl)-phenoxyl++ +-hexanoic acid) was found to be a potent and selective inhibitor of [3H]LTD4 specific binding to guinea pig lung membranes (IC50 2.4 +/- 1.0 nM), and also a potent, orally active, antagonist of LTD4 induced
本文介绍了结构修饰,导致发现了一系列新的含喹啉的cys-LT1受体(LTD4受体)拮抗剂。为了获得目标化合物OT4003,进行了关于体外受体结合,体内支气管收缩和过氧化物酶体增殖形式的毒理学效应的结构优化。发现OT4003((S)-(+)-E-2-(3-(2-(7-氯喹啉-2-基)乙烯基)苯基氨基甲基)-苯氧基++ +己酸)是一种有效的选择性抑制剂[3H] LTD4与豚鼠肺膜特异性结合(IC50 2.4 +/- 1.0 nM),也是强效,口服活性的LTD4诱导豚鼠支气管收缩的拮抗剂[ED50 0.14(ED16 0.1-ED84 0.4)mg / kg ; 预处理4小时]。
