human parathyroid hormone

Parathyroid Hormone (1-34), human, biotinylated is a probe targeting the parathyroid hormone receptor, used to analyze parathyroid hormone-receptor interactions within living cells and to purify hormone-receptor complexes via affinity columns [1] [2].

Teriparatide is an agonist of PHT(IC50 of 2 nM in HEK293 cells).

Upacicalcet (AJT-240) is an intraventricular calcium mimetic, a SHPT available for human hemodialysis, that inhibits excessive parathyroid hormone (PTH) secretion by directly acting on parathyroid cell membrane calcium-sensitive receptors, thereby lowering blood levels of PTH.Upacicalcet is an orthosteric modulator of calcium-sensitive receptors and prevents adenine-induced secondary vascular calcification and bone disease in a rat model of adenine-induced secondary hyperparathyroidism.

CH5447240 is an effective Human Parathyroid Hormone 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 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.

DS69910557, a potent, selective, and orally active antagonist of the human parathyroid hormone receptor 1 (hPTHR1), exhibits antagonistic activity with an IC50 value of 0.08 μM. It is useful in researching hyperparathyroidism, hypercalcemia of malignancy, and osteoporosis.

'(Tyr36)-pTH-Related Protein (1-36) (human, mouse, rat), a peptide, functions as a ligand for parathyroid hormone (PTH) receptors [1].'

Osteostatin (human), a fragment derived from parathyroid hormone-related protein (PTHrP) 107-139, effectively promotes bone repair in animal models with bone defects and inhibits bone erosion in cases of inflammatory arthritis [1].

Human PTH-(1-31), the 1-31 fragment of human parathyroid hormone, stimulates cAMP release and mildly activates 25-hydroxyvitamin D-1α-hydroxylase. Unlike its full-length counterpart, it promotes bone formation without triggering bone resorption, making it a promising candidate for osteoporosis research [1] [2].

pTH (1-37) (human), a fragment of parathyroid hormone (PTH), promotes cAMP formation and enhances alkaline phosphatase activity. Additionally, it fosters growth, elevates bone calcium content, and augments bone mineral density (BMD) in uremic animals. This compound shows promise for osteoporosis research [1] [2] [3].

pTH-Related Protein (1-40) (human, mouse, rat) enhances calcium absorption in rat intestinal cells by activating the PTHR1 receptor and the PKCα/β signaling pathways. This compound also increases the expression of the parathyroid hormone 1 receptor (PTHR1) and four key proteins involved in transcellular calcium transport: potential vanillin member 6 (TRPV6), calcium-binding protein-D9K (CaBP-D9k), sodium-calcium exchanger 1 (NCX1), and plasma membrane calcium ATPase 1 (PMCA1) [1].

Human PTHrP-(1-36) is a secreted parathyroid hormone-related protein with anticalciuric effects, promoting beta cell function and proliferation, and is used in research on humoral hypercalcemia of malignancy (HHM) and hyperparathyroidism [1] [3].

PTH-Related Protein (7-34) amide (human, mouse, rat) serves as a potent antagonist of parathyroid hormone (PTH) [1].

PTH-Related Protein (1-37) (human, mouse, rat) is a peptide analog of parathyroid-hormone-related protein (pTHrP), which plays a role in the physiological regulation of bone formation [1].

Osteostatin (1-5) amide (human, bovine, dog, horse, mouse, rabbit, rat), also known as Human PTHrP (107-111) amide, is a C-terminal fragment of parathyroid hormone-related protein that inhibits bone resorption [1][2].

Adrenocorticotropic hormone (6-24) (ACTH (6-24) (human)) is a fragment of ACTH that acts as a competitive inhibitor of steroidogenesis prompted by full-length ACTH (1-39) and the shortened ACTH (5-24), with dissociation constants (Kd) of 13.4 nM and 3.4 nM, respectively. It also impedes the production of corticosterone and the accumulation of cyclic AMP (cAMP) triggered by human parathyroid hormone (hPTH 1-34) [1] [2].

This is a tuberoinfundibular neuropeptide and parathyroid hormone 2(PTH 2)-receptor agonist from hypothalmus. Synthetic TIP39 activates human and rat PTH2 receptors.

KP-2067 is a peptide agonist of the CaSR receptor. It induces dose-dependent activation of CaSR in an overexpressing human CaSR HEK293T cell line, exhibiting an EC50 value of 18.4 μM. In rat models, KP-2067 significantly reduces plasma parathyroid hormone levels.
