Abstract

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 6.6 +/- 1.5 nM, and demonstrates potent oral and topical antiinflammatory activity in a murine model of dermal inflammation.
