Discovery of novel and potent orally active calcium-sensing receptor antagonists that stimulate pulselike parathyroid hormone secretion: Synthesis and structure-activity relationships of tetrahydropyrazolopyrimidine derivatives

As part of our research for novel calcium-sensing receptor (CaSR) antagonists that can function as oral bone anabolic agents, we recently reported the discovery of a tetrahydropyrazolopyrimidine derivative featuring adamantyl group 1b with potent CaSR ant
