Abstract:
Background: 5-LO is an important enzyme involved in the biosynthesis of leukotrienes, which are lipid mediators of immune and inflammation responses, with important roles in respiratory disease, cardiovascular disease, immune responses and certain types of cancer. Therefore, this enzyme has been investigated as a potential target for the treatment of these pathophysiological conditions. Results: 5-LO inhibitory potential was investigated in intact polymorphonuclear leukocytes, a cell-free assay, in human whole blood and rodent cells to both elucidate structure–activity relationships and in vitro pharmacological evaluation. Chemical modifications for lead optimization via straight forward synthesis was used to combine small polar groups, which led to a suitable candidate (IC 50 [polymorphonuclear leukocytes] = 1.15 µM, IC 50 [S100] = 0.29 µM) with desired in vitro biopharmaceutical profiles in terms of solubility (451.9 µg/ml) and intrinsic clearance without demonstrating any cytotoxicity. Conclusion: Compound 9l is a novel, potent and selective 5-LO inhibitor with favorable preclinical drug-like properties.
