NPS 2390

Customer Review

Based on 1 Customer Validation

NPS 2390 is an allosteric antagonist of calcium-sensing receptor (CaSR) and mGluR1/5. NPS 2390 inhibits the PI3K/Akt/mTOR signaling pathway, reduces hypoxia-induced intracellular calcium elevation, decreases the expression of autophagy (autophagy) proteins, regulates the expression of phenotypic marker proteins, and inhibits the proliferation of pulmonary artery smooth muscle cells. NPS 2390 attenuates the endogenous apoptosis (apoptosis) pathway, increases the expression level of Bcl-2, downregulates the expression levels of Bax, cytochrome c and caspase-3, alleviates cerebral edema and improves neurological function in rat models. NPS 2390 can be used in studies related to hypoxic pulmonary hypertension, traumatic brain injury, stroke and pain.

In Vitro

NPS 2390 (10 µM; 24 h) inhibits hypoxia-induced proliferation and reverses phenotypic modulation in human pulmonary arterial smooth muscle cells by reducing autophagy levels^[1].
NPS 2390 (10 µM; 24 h) suppresses hypoxia-induced increases in intracellular calcium concentration in human pulmonary arterial smooth muscle cells^[1].
NPS 2390 (10 µM; 24 h) activates the PI3K/Akt/mTOR signaling pathway in hypoxic human pulmonary arterial smooth muscle cells, which mediates its autophagy-inhibiting effects^[1].
NPS 2390 (multiple concentrations; 45 min) potently inhibits mGluR1 activity in rat cerebellar granule cells with an IC₅₀ of 0.005 μM^[3].

Western Blot Analysis^[1]

Cell Line:

human pulmonary arterial smooth muscle cells (HPASMCs)
Concentration:

10 µM
Incubation Time:

24 h (under hypoxia)
Result:

Increased the expression of phosphorylated PI3K, phosphorylated Akt, and phosphorylated mTOR, reversing the hypoxia-induced reduction in their phosphorylation levels.

In Vivo

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
