CH5447240 is an effective HumanParathyroidHormone Receptor 1 (hPTHR1) Agonist for the treatment of Hypoparathyroidism. CH5447240 showed a potent in vitro hPTHR1 agonist effect (EC20: 3.0 nM; EC50: 12 nM). It showed 55% oral bioavailability and a signifi
DPC-AJ1951 is a peptide agonist of the parathyroidhormone (PTH) PTH-related peptide receptor (PPR; EC50 = 0.15 nM in HEK293 cells expressing human PPR). It induces cAMP production in SAOS-2 and UMR106 cells that endogenously express human and rat PPR, respectively (EC50s = 2.2 and 1.1 nM, respectively). DPC-AJ1915 stimulates osteoclast-mediated bone resorption in fetal rat long-bone explant cultures and increases collagen synthesis and cell proliferation in neonatal mouse parietal bone explants. In vivo, DPC-AJ1951 normalizes serum calcium levels in thyroidparathyroidectomized rats.
This is a tuberoinfundibular neuropeptide and parathyroidhormone 2(PTH 2)-receptor agonist from hypothalmus. Synthetic TIP39 activates human and rat PTH2 receptors.
