Discovery of selective imidazole-based inhibitors of mammalian 15-lipoxygenase: Highly potent against human enzyme within a cellular environment

A series of 2,4,5-tri-substituted imidazoles has proven to be highly potent in inhibiting mammalian 15-lipoxygenase (15-LO) with excellent selectivity over human isozymes 5- and P-12-LO. Non-symmetrical sulfamides (e.g., 21a–n) were found to be suitable replacements for the earlier arylsulfonamide-containing members of this series (e.g., 2, 14a–p). Several members of these series also demonstrated potent inhibition of human 15-LO in a cell-based assay.
