GMX1778(CHS-828) is a potent inhibitor of NAD+ biosynthesis enzyme NAMPT with IC50 <25 nM.IC50 value: < 25 nM [1]Target: NAMPT inhibitorin vitro: The phosphoribosyltransferase activity of recombinant NAMPT was sensitive to inhibition by 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 (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 GMX1778 [1]. GMX1778 increases intracellular ROS in cancer cells by elevating the superoxide level while decreasing the intracellular NAD(+) level. Notably, GMX1778 treatment does not induce ROS in normal cells. GMX1778-induced ROS can be diminished by adding nicotinic acid (NA) in a NA phosphoribosyltransferase 1 (NAPRT1)-dependent manner [2].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 GMX1777 at a dose of 150 mg/kg or 650 mg/kg in the NAPRT1-deficient xenograft experiments. GMX1777 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 GMX1777 reduced the mortality associated with toxic doses of GMX1777 [1].

In vivo: P7C3 is orally bioavailable, crosses the blood-brain barrier, and is non-toxic at doses several fold higher than the efficacious dose.An easily administered pro-neurogenic compound. The administration of P7C3 is 10mg/ kg( IP) in rats. Administration of P7C3 to normal mice, as well as npas3-/- mice, enhance survival of neurons subsequent to their birth in the SGZ.

STF-118804 displays distinctive cytotoxicity by inducing apoptosis without causing a phase-specific cell cycle arrest. Over-expression of NAMPT rendered 293T cells more resistant to STF-118804 resulting in a higher IC50 (106 nM, 95% CI 74–151 nM) compared to control cells (17 nM, 95% CI 13–23 nM), further confirming that NAMPT protein levels dictate sensitivity to STF-118804 [1].in vivo: STF-118804 displayed high efficacy in a xenograft model of ALL. Mice treated with STF-118804 over a 20-day period survived an average of 34 days longer than vehicle-treated animals. During treatment, bioimaging showed regression of tumor followed by suppression of disease. STF-118804 was tolerated in the efficacious dose range, and the absence of adverse physical or pathological effects indicated that toxicity was not limiting in a 20-day study of mock transplanted mice [1].
