NF449

7 Cited Publications

고객리뷰

Based on 7 publication(s) in Google Scholar

NF449 is a highly potent P2X₁ receptor antagonist, with IC₅₀s of 0.28, 0.69, and 120 nM for rP2X₁, rP2X₁₊₅, P2X₂₊₃, respectively. NF449 is a G_sα-selective G Protein antagonist. NF449 suppresses the rate of GTP[γS] binding to G_sα-s, inhibits the stimulation of adenylyl cyclase activity, and blocks the coupling of β-adrenergic receptors to G_s.

All P2X Receptor Isoforms :

In Vitro

NF449 suppressed the rate of GTP[γS] binding to rG_sα-s while barely affecting binding to rG_iα-1 (IC₅₀=140 nM), inhibits stimulation of adenylyl cyclase activity in S49 cyc membranes (deficient in endogenous Gsα) by exogenously added Gsα-s, and blocks the coupling of β-adrenergic receptors to G_s (EC₅₀=7.9 μM)^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

At a dose of 10 mg/kg, NF449 inhibits the ex vivo aggregation triggered by 5 g/ml collagen in WT mouse platelets without affecting that induced by 5 μM ADP. At a higher dose (50 mg/kg), NF449 inhibits ex vivo platelet aggregation in response to not only 10 g/ml collagen but also 5 M ADP, indicating nonselective inhibition of the P2Y1 and/or P2Y12 receptor^[3].

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.
