3-epi-25-hydroxy Vitamin D3is the C-3 epimer of 25-hydroxy vitamin D3.1Dietary administration of 3-epi-25-hydroxy vitamin D3(0.5 and 1 IU g) decreases levels of serum parathyroid hormone (PTH) in male, but not female, weanling rats. 1.Djekic-Ivankovic, M., Lavery, P., Agellon, S., et al.The C-3α epimer of 25-hydroxycholecalciferol from endogenous and exogenous sources supports normal growth and bone mineral density in weanling ratsJ.

DPC-AJ1951 is a peptide agonist of the parathyroid hormone (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 parathyroid hormone 2(PTH 2)-receptor agonist from hypothalmus. Synthetic TIP39 activates human and rat PTH2 receptors.
parathyroid hormone (7-34) [Homo sapiens] [Macaca fascicularis] is a peptide with the sequence H2N-LMHNLGKHLNSMERVEWLRKKLQDVHNF-OH, MW= 3474.03. Parathyroid hormone (PTH) is secreted by the chief cells of the parathyroid glands as a polypeptide containing
