Biological Activity

Description GMX1778 is a potent and specific inhibitor of nicotinamide phosphoribosyltransferase (NAMPT) with IC50 and Kd of < 25 nM and 120 nM, respectively. GMX1778 induces programmed cell death with apoptotic features. Phase 1.
Targets
NAMPT [1] NAMPT [1]
<25 nM 120 nM(Kd)
In vitro

GMX1778 induces NAD+ depletion through inhibition of NAD+ biosynthesis, followed by ATP depletion and ultimately resulted in cell death. [1] GMX1778 induces programmed cell death with apoptotic features. [2] GMX1778 suppresses nuclear factor-kappa B activity in cancer cells through downregulation of IKK activity (IC50=8 nM). [3]
In vivo

GMX1778 (250 mg/kg, p.o.) shows marked antitumoural activity against three different human neuroendocrine tumours, midgut carcinoid (GOT1), pancreatic carcinoid (BON), and medullary thyroid carcinoma (GOT2), transplanted in nude mice. [4]

Protocol (from reference)

Kinase Assay:

[1]
  • In vitro coupled-enzyme NAMPT assay

    Recombinant NAMPT activity is assessed using a coupled-enzyme assay based on the quantitation of NAD+. Reactions are performed at room temperature for 180 min using mixtures consisting of 50 mM HEPES (pH 7.4), 50 mM KCl, 5 mM MgCl2, 0.5 mM β-mercaptoethanol, 0.005% bovine serum albumin, 1% DMSO, 2.0 U/ml lactate dehydrogenase, 4 mM sodium L-lactate, 0.4 U/ml diaphorase, 6 μΜ resazurin sodium salt, 0.4 mM PRPP, 3.0 nM NMNAT1, 125 μM ATP, 50 μM NM, and 2 to 5 μM recombinant NAMPT. Fluorescence s measured with a Tecan Safire plate reader (excitation wavelength, 560 nm; emission wavelength, 590 nm). Ki values are calculated using Graphpad Prism 4.0 software and the Cheng-Prusoff equation.
Cell Assay:

[1]
  • Cell lines

    HeLa cells

  • Concentrations

    ~100 nM

  • Incubation Time

    72 h

  • Method

    Serial dilutions of GMX1778 in DMSO are performed to achieve a final concentration of 0.2% DMSO. Relative ATP levels after 72 h are determined using a ViaLight HS high-sensitivity cytotoxicity and cell proliferation BioAssay kit per the manufacturer's instructions. For GMX1778 cytotoxicity rescue experiments, cells are treated with NA (10 μM)  simultaneously with GMX1778. Sigmoidal dose-response curves are generated by nonlinear regression analysis of variable slope using GraphPad Prism version 4.00 (GraphPad Software) to calculate 50% inhibitory (IC50) values.
Animal Study:

sup>[4]
  • Animal Models

    Nude mice bearing midgut carcinoid (GOT1), pancreatic carcinoid (BON) and medullary thyroid cancer (GOT2) tumors

  • Dosages

    ~250 mg/kg

  • Administration

    p.o.
