Abstract

We report the further optimization of our series 1H-pyrazolo[3,4-g]hexahydro-isoquinoline sulfonamides as GR antagonists. By incorporating a heteroaryl ketone group at the ring junction, we have obtained compounds with excellent functional GR antagonism. Optimization of the sulfonamide substituent has provided compounds with a very desirable overall profile, including minimal hERG activity, good bioavailability and in vivo efficacy.
