In Vitro

The phosphoribosyltransferase activity of recombinant NAMPT was sensitive to inhibition by CHS-828 (GMX1778) (IC50 < 25 nM) whereas the adenyltransferase activity of recombinant NMNAT1 was not. The Kd of recombinant NAMPT for GMX1778 labeled with a fluorescent tag (CHS-828 (GMX1778)-Alexa Fluor) was 120 nM. Overexpression of wild-type NAMPT was able to maintain a certain level of NAD+ under conditions of challenge with 3 nM GMX1778, but this effect was lost when cells were exposed to 300 nM CHS-828 (GMX1778)^[1]. CHS-828 (GMX1778) increases intracellular ROS in cancer cells by elevating the superoxide level while decreasing the intracellular NAD(+) level. Notably, CHS-828 (GMX1778) treatment does not induce ROS in normal cells. CHS-828 (GMX1778)-induced ROS can be diminished by adding nicotinic acid (NA) in a NA phosphoribosyltransferase 1 (NAPRT1)-dependent manner^[2].

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

In Vivo

A 4-h iv infusion of NA (120 mg/kg of body weight) did not adversely affect the antitumor activity of a 24-h iv infusion of CHS-828 (GMX1778) at a dose of 150 mg/kg or 650 mg/kg in the NAPRT1-deficient xenograft experiments. CHS-828 (GMX1778) at 650 mg/kg is above the maximum tolerated dose. The administration of NA as a 4-h iv infusion immediately following treatment with 750 mg/kg CHS-828 (GMX1778) reduced the mortality associated with toxic doses of GMX1777^[2].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (6.72 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

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.
