A series of hydroxyacetophenones was prepared for evaluation as leukotriene B4 (LTB4) receptor antagonists, culminating in 1-oxy>phenyl>ethanone (compound 35, LY255283).Using an assay for inhibition of specific LTB4 binding to human PMN, we found that substitution of a nonpolar substituent in the 5-position was required for activity.Best activity was realized with hydrogen in the 3-position, hydroxyl in the 2-position, short chain alkyl ketone in the 1-position, and a six- or eight-carbon chain linking the oxygen in the 4-position with an unsaturated terminal function.Compound 35, having an IC50 of 87 nM in the binding assay, was chosen for further preclinical evaluation.
