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.

     N-formyl-Met-Leu-Phe (fMLP; 10 nM) are used to stimulate the cells for 2 min, and the polymorphonuclear neutrophils (PMNs) without fMLP serve as the control. NPS-2143 (100 nM), Cinacalcet (100 nM), and PDTC (100 nM) are added and incubated. Protein expression results are representative of three experiments.

    Customer Validation
     Distribution of cardioprotective signaling kinases among fractions prepared from perfusion, IPC, and NPS2143-treated IPC hearts. After nondetergent caveolae fractionation via sucrose gradient ultracentrifugation, equal volume of each collected sucrose fraction is subjected to 4–12% SDS-PAGE under reducing condition and followed with p-ERK1/2 (A), p-AKT (B), and p-GSK-3β (C) IB detection. The representative IBs are taken and shown from one out of three independent experiments.
