We report the discovery of a series of novel zwitterionic hPTHR1 antagonists. Optimization of lead compound 2 led to 4-[[1-[4-(2,9-dichloro-5,5-dimethyl-6-oxo-pyrido[2,3–d][1]benzazepin-7-yl)phenyl]-3-fluoro-azetidin-3-yl]methylamino]cyclohexanecarboxylic acid (19e, DS69910557), a compound with excellent potency and selectivity over activity at the human ether-a-go-go-related-gene (hERG) channel.
