Abstract

The cyclic carbamate derivatives, 2-{[2-((4S)-4-{(1E,3R)-8-fluoro-3-hydroxy-4,4-dimethyl-1-octenyl}-2-oxo-1,3-oxazolidin-3-yl)ethyl]sulfanyl}-1,3-thiazole-4-carboxylic acid (5) and 2-{[2-((4S)-4-{(1E,3R)-3-[1-(4-fluorobutyl)cyclobutyl]-3-hydroxy-1-propenyl}-2-oxo-1,3-oxazolidin-3-yl)ethyl]sulfanyl}-1,3-thiazole-4-carboxylic acid (7) were identified as the first potent dual EP2 and EP3 agonists with selectivity against the EP1 and EP4 subtypes. Compounds 5 and 7 demonstrated highly potent dual EP2 and EP3 agonist activity with EC50 values of 10nM or less. In addition, these compounds possess structural features distinct from natural prostaglandins, such as a cyclic carbamate moiety, a dimethyl or cyclobutyl group and a terminal fluorine atom.

Keywords: Dual agonist; EP(2) receptor; EP(3) receptor; Prostaglandin; Underactive bladder.
