This study demonstrates that SC-41930, 7-[3-(4-acetyl-3-methoxy-2-propylphenoxy)-propoxy]-3,4-dihydro-8-p ropyl-2H-1-benzopyran-2-carboxylic acid, an orally active LTB4 receptor antagonist, reduces LTB4-induced leukocyte adhesion and emigration in rat mesenteric venules. The mesentery of Sprague-Dawley rats was prepared for intravital microscopic examination and venules of 25-35 microns were chosen for evaluation. In control animals, LTB4 (20 nM) was superfused over the mesentery for 30 min. In the treatment group SC-41930 (5 microM) was superfused for 30 min, followed by a 30 min superfusion with SC-41930 and LTB4. The LTB4-induced increase in leukocyte adherence and emigration in postcapillary venules was significantly attenuated by pretreatment with SC-41930. Other experiments demonstrated that platelet-activating-factor-induced leukocyte adherence was not affected by SC-41930. These results indicate that SC-41930 is a potent inhibitor of LTB4-induced leukocyte-endothelial cell adhesive interactions in postcapillary venules.
