NPS 2143, a selective calcium-sensing receptor antagonist inhibits lipopolysaccharide-induced pulmonary inflammation
NPS 2143, a novel and selective antagonist of calcium-sensing receptor (CaSR) has been reported to possess anti-inflammatory activity. In the present study, we examined the protective effect of NPS 2143 on lipopolysaccharide (LPS)-induced acute lung injury (ALI). NPS 2143 pretreatment significantly inhibited the influx of inflammatory cells and the expression of monocyte chemoattractant protein-1 (MCP-1) in the lung of mice with LPS-induced ALI. NPS 2143 decreased the levels of neutrophil elastase (NE) and protein concentration in the bronchoalveolar lavage fluid (BALF). NPS 2143 also reduced the production of inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the BALF and serum. In addition, NPS 2143 attenuated the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), and increased the activation of AMP-activated protein kinase (AMPK) in the lung. NPS 2143 also downregulated the activation of nuclear factor-kappa B (NF-κB) in the lung. In LPS-stimulated H292 airway epithelial cells, NPS 2143 attenuated the releases of IL-6 and MCP-1. Furthermore, NPS 2143 upregulated the activation of AMPK and downregulated the activation of NF-κB. These results suggest that NPS 2143 could be potential agent for the treatment of inflammatory diseases including ALI.
Calcium-Sensing Receptor Antagonist NPS-2143 Inhibits Breast Cancer cell Proliferation, Migration and Invasion via Downregulation of p-ERK1/2, Bcl-2 and Integrin β1 and Induces Caspase 3/7 Activation
Purpose: Calcium-sensing receptor (CaSR) has been associated with breast cancer metastasis tothe bone. Targeting chemoattractant factors, such as calcium, that are released in response tobone resorption could prevent metastasis and induce apoptosis of cancer cells. In the presentstudy, we investigated the potential caspase 3/7 activation following treatment with a CaSRantagonist, NPS-2143, in breast cancer cells. In addition, the effects of NPS-2143 on breastcancer cell proliferation, migration and invasion were assessed. Methods: Colorimetric MTT assay was used to evaluate cell viability. Apo-one homogeneouscaspase-3/7 assay was used to measure caspase 3/7 activities in breast cancer cells. Cellmigration and invasion were assessed using scratch wound assay and matrigel invasionchambers, respectively. The protein expressions of p-ERK1/2, integrin β1 and Bcl-2 wereevaluated using western blotting. Results: Our study revealed that NPS-2143 significantly reduced cell proliferation with halfmaximal (50%) inhibitory concentration (IC50) values of 4.08 and 5.71 μM in MDA-MB-231 and MCF-7 cells, respectively. NPS-2143 induced caspase 3/7 activation in MDA-MB-231 breastcancer cells which was accompanied with a remarkable reduction in the expression of Bcl-2antiapoptotic protein. NPS-2143 suppressed migratory and invasive abilities of MDA-MB-231cells with a significant reduction in the expression of p-ERK1/2 and integrin β1 proteins. Conclusion: Our study confirms the ability NPS-2143 to suppress proliferative, migratory andinvasive effects of breast cancer cells which was accompanied by caspase 3/7 activation andsuggests the potential of NPS-2143 as a promising anti-cancer molecule in breast cancer.
Calcium-sensing receptor antagonist NPS-2143 suppresses proliferation and invasion of gastric cancer cells
NPS-2143 is a calcium-sensing receptor (CaSR) antagonist that has been demonstrated to possess anticancer activity. To date, the effects of NPS-2143 on gastric cancer (GC) cell growth, motility, and apoptosis have not been investigated. In the present study, we firstly investigated the expression of CaSR in GC tissues using immunohistochemistry and western blotting. Then Cell Counting Kit-8 and colony formation assays were conducted to explore the effect of the NPS-2143 on the proliferation of GC cell line AGS. Transwell invasion and migration assays were performed to test the effect of NPS-2143 on AGS cell motility. We determined the percentage of apoptotic cells by flow cytometry and explored the changes of apoptosis-related protein by western blotting. Furthermore, we constructed a CaSR knockdown AGS cell line to determine whether NPS-2143 acted via inhibition of CaSR. We found that the protein expression level of CaSR was higher in GC tissues compared with the paired adjacent normal tissues. In addition, NPS-2143 treatment caused an inhibitory effect on the proliferation, invasion, and migration of AGS cells and a promoting effect on AGS apoptosis. The expression of Bcl-2 was decreased while the levels of Bax and active caspase 3 were enhanced in AGS cells after NPS-2143 treatment. Mechanistically, NPS-2143 lead to a significant decrease in the expression of phosphorylated (p)-AKT, phosphorylated mechanistic target of rapamycin (p-mTOR), p70, and cyclin D1. Knockdown of CaSR also suppressed cell proliferation, invasion, and migration and promoted cell apoptosis. No significant difference was observed between CaSR-silenced AGS cells with and without NPS-2143 treatment. These results confirmed that NPS-2143 has an inhibitory influence on AGS cell growth via inhibiting CaSR, which then suppresses the PI3K/Akt signaling pathway.
NPS - 2143 (hydrochloride) inhibits melanoma cancer cell proliferation and induces autophagy and apoptosis
Melanoma is a common and aggressive skin cancer caused by the oncogenic transformation of melanocytes. NPS-2143 (hydrochloride) is a calcification drug that acts as an antagonist of the calcium-sensing receptor (CaSR) and consequently stimulates the release of parathyroid hormone. In the present work, we treated cells from the human melanoma cell line M14 to investigate the effects of NPS-2143 on melanoma cells and elucidate their underlying mechanisms. We observed that NPS-2143 inhibits the survival and proliferation of M14 cells and suppresses the migration and proliferation of M14 cells by inducing apoptosis. The Bax/Bcl?2 ratio in M14 cells was enhanced by the NPS-2143 treatment, suggesting that the mitochondrial apoptotic pathway was activated. The expression and phosphorylation of proteins involved in the PI3K signaling pathway were altered by NPS-2143 treatment. Our data show that NPS-2143 impacts the viability and induces the apoptosis of melanoma M14 cells through its impact on the PI3K signaling pathway. It suggests that NPS-2143 could represent a promising candidate for melanoma treatment.
Calcilytic NPS 2143 Reduces Amyloid Secretion and Increases sAβPPα Release from PSEN1 Mutant iPSC-Derived Neurons
Despite numerous efforts and studies over the last three decades, Alzheimer's disease (AD) remains a disorder not fully understood and incurable so far. Development of induced pluripotent stem cell (iPSC) technology to obtain terminally differentiated neurons from adult somatic cells revolutionized the study of AD, providing a powerful tool for modelling the disease and for screening candidate drugs. Indeed, iPSC reprogramming allowed generation of neurons from both sporadic and familial AD patients with the promise to recapitulate the early pathological mechanisms in vitro and to identify novel targets. Interestingly, NPS 2143, a negative allosteric modulator of the calcium sensing receptor, has been indicated as a possible therapeutic for AD. In the present study, we assessed the potential of our iPSC-based familial AD cellular model as a platform for drug testing. We found that iPSC-derived neurons respond to treatment with γ-secretase inhibitor, modifying the physiological amyloid-β protein precursor (AβPP) processing and amyloid-β (Aβ) secretion. Moreover, we demonstrated the expression of calcium sensing receptor (CaSR) protein in human neurons derived from healthy and familial AD subjects. Finally, we showed that calcilytic NPS 2143 induced a changing of Aβ and sAβPPα secreted into conditioned media and modulation of CaSR and PSEN1 expression at the plasma membrane of AD neurons. Overall, our findings suggest that NPS 2143 affects important AD processes in a relevant in vitro system of familial AD.
