Discovery and Characterization of Novel, Potent, Non-Peptide Parathyroid Hormone-1 Receptor Antagonists
摘要:
A 1,3,4-benzotriazepine was identified as a suitable lead in our effort toward obtaining a non-peptide parathyroid hormone-1 receptor (PTHIR) antagonist. A process of optimization afforded derivatives displaying nanomolar PTHIR affinity, a representative example of which behaved as a PTHIR antagonist in cell-based cyclic adenosine monophosphate (cAMP) assays, with selectivity over PTH2 receptors.
