Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

CaSR [1]
2.8 μM(EC50)
In vitro

AMG-073 represents a new class of compounds for the treatment of hyperparathyroidism known as calcimimetics, which reduce parathyroid hormone (PTH) synthesis and secretion by increasing the sensitivity of the parathyroid calcium-sensing receptor (CaR) to extracellular calcium. AMG-073 has potential advantages as a therapy for secondary hyperparathyroidism because it mimics the effects of extracellular calcium to suppress PTH secretion, even in the presence of hyperphosphatemia, without the risk of causing hypercalcemia and/or hyperphosphatemia. AMG-073 produces a concentration-dependent increase in cytoplasmic calcium in human embryonic kidney cells expressing the CaSR. In bovine parathyroid cells and a buffer containing calcium 0.5 mM, AMG 073 (3 nM – 1 μM) produces a concentration-dependent decrease in PTH levels with IC50 of 27 nM. [2]

In vivo

AMG-073 orally administrated to normal rats at dose of 1, 3, 10, and 30 mg/kg in 20% sulfobutyl ether β-cyclodextrin sodium produces a significant dose-dependent reduction in PTH levels for 1 to 4 hours after administration. At 8 hours, the 10- and 30-mg/kg doses of AMG-073 produces significant reductions in PTH levels compared with controls that disappears by 24 hours. Significant dose-dependent reduction in serum calcium levels are observed at 4, 8, and 24 hours after oral administration of AMG-073 3, 10, and 30 mg/kg, respectively. A transient reduction in serum phosphorus levels is observed only with the highest dose of AMG-073. In addition, increased calcitonin levels that paralleled PTH suppression are observed with AMG-073 40 mg/kg in rats. As in normal rats, a rapid dose-dependent reduction in PTH and calcium levels is observed in 5 of 6 nephrectomized rats after oral administration of AMG-073. In addition, oral AMG-073 at 5 and 10 mg/kg for 4 weeks significantly reduces parathyroid weight compared with controls. [2]
