BioAssay: AID 650762

Inhibition of 5-lipoxygenase in human polymorphonuclear leukocytes assessed as reduction in A23187 and AA-stimulated 5-LO product formation preincubated for 15 mins prior stimulation measured after 10 mins by HPLC analysis

A novel class of 5-lipoxygenase (5-LO) inhibitors characterized by a central imidazo[1,2-a]pyridine scaffold, a cyclohexyl moiety and an aromatic system, is presented. This scaffold was identified in a virtual screening study and exhibits promising inhibitory potential on the 5-LO. Here, we investigate the structure-activity relationships of this compound class.

Description:
Title: SAR-study on a new class of imidazo[1,2-a]pyridine-based inhibitors of 5-lipoxygenase.

Abstract: A novel class of 5-lipoxygenase (5-LO) inhibitors characterized by a central imidazo[1,2-a]pyridine scaffold, a cyclohexyl moiety and an aromatic system, is presented. This scaffold was identified in a virtual screening study and exhibits promising inhibitory potential on the 5-LO. Here, we investigate the structure-activity relationships of this compound class. With N-cyclohexyl-6-methyl-2-(4-morpholinophenyl)imidazo[1,2-a]pyridine-3-amine (14), we identified a potent 5-LO inhibitor (IC(50)=0.16muM (intact cells) and 0.1muM (cell-free)), which may possess potential as an effective lead compound intervening with inflammatory diseases and certain types of cancer.
