Arylsulfonylcarbamic acid esters, thioesters, and amides, 3, have been prepared via catalytic carbonylation of alkali metal salts of N-chloroarylsulfonamides, 1, and treatment of the reaction mixture with R1XH (XO, S, NR2).

Two new series of EP4 antagonists based on naphthalene/quinoline scaffolds have been identified as part of our on-going efforts to develop treatments for inflammatory pain. One series contains an acidic sulfonylurea pharmacophore, whereas the other is a neutral amide. Both series show subnanomolar intrinsic binding potency towards the EP4 receptor, and excellent selectivity towards other prostanoid receptors. While the amide series generally displays poor pharmacokinetic parameters, the sulfonylureas exhibit greatly improved profile. MF-592, the optimal compound from the sulfonylurea series, has a desirable overall preclinical profile that suggests it is suitable for further development. (C) 2010 Elsevier Ltd. All rights reserved.
