Pyrazole-based sulfonamide and sulfamides as potent inhibitors of mammalian 15-lipoxygenase
摘要:
A series of inhibitors of mammalian 15-lipoxygenase (15-LO) based on a 3,4,5-tri-substituted pyrazole scaffold is described. Replacement of a sulfonamide functionality in the lead series with a sulfamide group resulted in improved physicochemical properties generating analogs with enhanced inhibition in cell-based and whole blood assays.

A Mn‐electrocatalytic ring‐opening azidation of tert‐cyclobutanols has been developed. The regioselective method is applicable for the azidation of a diverse array of cyclobutanols to provide γ‐azido ketones in 23‐91% yields under chemical oxidants‐free reaction conditions. Detailed mechanistic studies suggest the process of Mn‐mediated alkoxy radical generation followed by β‐scission to form carbon‐centered

A series of 2,4,5-tri-substituted imidazoles has proven to be highly potent in inhibiting mammalian 15-lipoxygenase (15LO) 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. (c) 2007 Elsevier Ltd. All rights reserved.
