Abstract

The discovery and optimization of a novel series of PTHR1 antagonists are described. Starting from known PTHR1 antagonists, we identified more potent 1,4-benzodiazepin-2-one derivatives by means of a scaffold-hopping approach. The representative compound 23 (DS08210767) exhibited nanomolar-level PTHR1 antagonist activity and potential oral bioavailability in a pharmacokinetic study.

Keywords

1,4-Benzodiazepin-2-one; PTH type 1 receptor (PTHR1) antagonist; Parathyroid hormone (PTH); Scaffold hopping.
