An extensive structure-activity study based around the high-affinity leukotriene B4 (LTB4) receptor antagonist SB 201146 (1) led to the identification of (E)-3-[6-[[(2,6-dichlorophenyl)-thio]methyl]-3-(2-phenylethoxy)-2- pyridinyl]-2-propenoic acid (3). This compound displays high affinity for the human neutrophil LTB4 receptor (Ki = 0.78 nM), blocks LTB4-induced Ca2+ mobilization with an IC50 of 6
基于高亲和力白三烯B4(LTB4)受体拮抗剂SB 201146(1)的广泛结构活性研究导致鉴定(E)-3- [6-[[((2,6-dichlorophenyl)-thio]甲基] -3-(2-苯基乙氧基)-2-吡啶基] -2-丙酸(3)。该化合物对人嗜中性白细胞LTB4受体具有高亲和力(Ki = 0.78 nM),阻断LTB4诱导的Ca2 +动员,IC50为6.6 +/- 1.5 nM,并在小鼠皮肤炎症模型中表现出强效的口服和局部抗炎活性。
