摘要: By use of parallel chemistry coupled with physicochemical property design, a series selective κ opioid antagonists have been discovered. The strategy utilized key monomer building blocks to rapidly expand the desired SAR space. potency and selectivity in vitro antagonism were confirmed tail-flick analgesia model. This model was used build an exposure–response relationship between Ki free brain drug levels. identified 2-methyl-N-((2′-(pyrrolidin-1-ylsulfonyl)biphenyl-4-yl)methyl)propan-1-amine, PF-4455242, which entered phase 1 clinical testing has demonstrated target engagement healthy volunteers.
