Overexpression of wild-type NAMPT was able to maintain a certain level of NAD+ under conditionsof challenge with 3 nM GMX1778, but this effect was lost when cells were exposed to 300 nM CHS-828(GMX1778) 1.

6、eases intracellular ROS in cancer cells by elevating the superoxidelevel while decreasing the intracellular NAD(+) level. Notably, CHS-828 (GMX1778) treatment does notinduce ROS in normal cells. CHS-828 (GMX1778)-induced ROS can be diminished by adding nicotinic acid(NA) in a NA phosphoribosyltransf
