生物活性

CHS-828 (GMX1778) is a competitive inhibitor of nicotinamide phosphoribosyltransferase (NAMPT), with an IC50 less than 25 nM. CHS-828 (GMX1778) exerts a cytotoxic effect by decreasing the cellular level of NAD+ and exhibits a potent anticancer activity[1].

IC50 & Target

IC50: < 25 nM (NAMPT)[1].

体外研究
(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].

体内研究
(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].
