4-((2-hydroxy-3-methoxybenzyl)amino)benzenesulfonamide derivatives as potent and selective inhibitors of 12-lipoxygenase
Human lipoxygenases (LOXs) are a family of iron-containing enzymes involved in catalyzing the oxidation of polyunsaturated fatty acids to provide the corresponding bioactive hydroxyeicosatetraenoic acid (HETE) metabolites. These eicosanoid signaling molecules are involved in a number of physiologic responses such as platelet aggregation, inflammation, and cell proliferation. Platelet-type 12-(S)-LOX (12-LOX) is of particular interest because of its demonstrated role in skin diseases, diabetes, platelet hemostasis, thrombosis, and cancer. Disclosed herein is the identification and medicinal chemistry optimization of a 4-((2-hydroxy-3-methoxybenzyl)amino)benzenesulfonamide-based scaffold. The compounds display nM potency against 12-LOX and excellent selectivity over related lipoxygenases and cyclooxygenases.
