CH5447240 is an effective Human ParathyroidHormoneReceptor 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
(1S)-Calcitriol (1α,25-Dihydroxy-3-epi-vitamin-D3) is a natural metabolite of 1α,25-dihydroxyvitamin D3 (1α,25(OH)2D3). (1S)-Calcitriol exhibits potent vitamin D receptor (VDR)-mediated actions such as inhibition of keratinocyte growth or suppression of parathyroidhormone secretion[1]. 3‐epi‐Calcitroic acid is an end product of (1S)-Calcitriol (1α,25-Dihydroxy-3-epi-vitamin-D3; 3‐epi‐1a,25(OH)2D3) metabolism by rat CYP24A1[1].

parathyroidhormone (7-34) [Homo sapiens] [Macaca fascicularis] is a peptide with the sequence H2N-LMHNLGKHLNSMERVEWLRKKLQDVHNF-OH, MW= 3474.03. Parathyroidhormone (PTH) is secreted by the chief cells of the parathyroid glands as a polypeptide containing
