Product Introduction

Bioactivity
Description
NPS-2143 hydrochloride (NPS-2143 HCL) is a selective potent calcium ion-sensing receptor antagonist.
Targets&IC50
CaSR:43nM/41nM
In vitro
NPS 2143, even when tested at much higher concentrations (3 microM), did not affect the activity of a number of other G protein-coupled receptors, including those most structurally homologous to the Ca2+ receptor. NPS 2143 stimulated parathyroid hormone (PTH) secretion from bovine parathyroid cells (EC50 of 41 nM) over a range of extracellular Ca2+ concentrations and reversed the effects of the calcimimetic compound NPS R-467 on [Ca2+]i and on secretion of PTH . The first reported calcilytic compound was NPS 2143, an orally active molecule which elicits rapid, 3- to 4-fold increases in circulating levels of PTH.
In vivo
When intravenously administered to normal rats, NPS 2143 swiftly elevated plasma PTH levels significantly. Known as calcilytics, substances like NPS 2143 act as Ca2+ receptor antagonists, with it being the inaugural compound (either atomic or molecular) identified with this activity [1]. Concurrent administration with an antiresorptive agent (estradiol) resulted in enhanced trabecular bone volume and bone mineral density in osteopenic rats.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
