ProtocolIn VitroNPS-2143 (SB-262470A) stimulates parathyroid hormone (PTH) secretion from bovine parathyroid cells with EC50 of 41 nM. Moreover, NPS 214 also blocks the inhibitory effects of calcimimetic NPS R-467 on PTH secretion from bovine parathyroid cells and the inhibitory effects of extracellular Ca2+ on isoproterenol-stimulated increases in cyclic AMP formation
In VivoNPS-2143 (SB-262470A) results in a rapid 4- to 5-fold increase in plasma PTH levels in rats

Calculation Results:
Working concentration: mg/ml;
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 add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
  • (2) Be sure to add the solvent(s) in order.
