Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 3.950mg/ml (10.01mM) Taking the 1 mL working solution as an example, add 50 μL of 79 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil

Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 0.490mg/ml (1.24mM) Taking the 1 mL working solution as an example, add 50 μL of 9.8 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description NGI-1 is an aminobenzamide-sulfonamide compound that targets both oligosaccharyltransferase (OST) isoforms and therefore may exhibit Antiviral activity against flaviviruses.
Targets
oligosaccharyltransferase (OST)
In vitro

NGI-1 is a reversible catalytic subunit inhibitor of the oligosaccharyltransferase (OST) that has higher specificity for STT3B compared to STT3A (STT: OST catalytic subunit). In non-small cell lung cancer cells this compound blocks cell surface localization and signalling of the EGFR glycoprotein, but selectively arrests proliferation in only those cell lines that are dependent on EGFR (or FGFR) for survival. In these cell lines OST inhibition causes cell cycle arrest accompanied by induction of p21, autofluorescence, and changes in cell morphology; all hallmarks of senescence. It exhibits broad Antiviral activity against multiple flaviviruses. This inhibitor blocks viral RNA replication independent of inhibition of the catalytic activity of the OST complex.
