  Leukotriene B4 (LTB4) Receptor Antagonists: A Series of (Hydroxyphenyl)pyrazoles

  摘要：

  A series of (hydroxyphenyl)pyrazoles was designed by molecular modeling comparison with the LTB(4) structure and prepared for evaluation as LTB(4) receptor antagonists, culminating in 4-ethyl-5-[[6-methyl-6-(1H-tetrazol-5-yl)heptyl]oxy]-2-(1H-pyrazol-3-yl)phenyl (2). Using an assay for inhibition of specific [H-3]LTB(4) binding to human PMN, it was found that the pyrazole ring could be methylated at N(1) with little loss of activity while methylation at N(2) reduced activity significantly. The structure-activity relationship of the terminal acid group was investigated. Good activity was found with o- and m-phenylalkanoic acids, chromane carboxylic acid, and tetrazole groups. The best in vitro activity was realized with the pyrazole nitrogen unsubstituted and with a six-carbon chain linking the phenyl ether oxygen to the tetrazole group. Compound 2, having an IC50 of 6.4 +/- 0.8 nM in the binding assay, was selected for further preclinical evaluation.
