A fluorimetric study on the spectral characteristics of two antileukotrienes, cinalukast and montelukast, has been performed. Ionization constants of both of them have been photometrically calculated. Cinalukast pK(a) in ethanol:water 50:50 (v/v) medium resulted to be 2.2+/-0.1. Because the spectral

Ro 24-5913, (E)-4-[3-[2-(4-cyclobutyl-2- thiazolyl)ethenyl]phenylamino]-2,2-diethyl-4-oxobutanoic acid, has been identified as a chemically unique, potent and selective LTD4 antagonist. In vitro, Ro 24-5913 competes with [3H]LTD4 for its binding site on guinea pig lung membranes with an IC50 of 6.4 +/- 2.2

Structure optimization of the leukotriene D4 antagonist Ro24-5913 was attempted by combinatorial chemistry. Three segments in its N-succinyl-3-(2-thiazolylethenyl)anilide skeleton, designated as A, B, and C coincided with the thiazolyl, aniline, and N-acyl moieties, respectively, and were selected for variations in
