• 產(chǎn)品描述： NPS-2143 (SB-262470A), an orally active calcilytic agent, is a selective and potent calcium ion-sensing receptor (CaSR) antagonist. NPS-2143 (SB-262470A) blocks increases in cytoplasmic Ca2+ concentrations (IC50=43 nM) elicited by activating the Ca2+ receptor in HEK 293 cells expressing the human Ca2+ receptor

• 靶點： IC50: 43 nM (Ca2+ receptor);CalciumChannel;CaSR

• 體內(nèi)研究：
  NPS-2143 (SB-262470A) results in a rapid 4- to 5-fold increase in plasma PTH levels in rats. In normotensive rats, NPS-2143 administration (1 mg/kg, i.v.) markedly increases mean arterial blood pressure (MAP) in the presence of parathyroid glands.
