APO866 effectively inhibits nicotinamide phosphoribosyltransferase (NMPRTase) with IC50 of 0.09 nM.

CHS-828 is a pyridyl cyanoguanidine anti-tumor agent that has been identified as a competitive inhibitor of Nampt as well as an inhibitor of NF-κB pathway activity.

LSN3154567 is a novel inhibitor of NAMPT with IC50 of 18 nM (NCI-H1155 cell), 49 nM (Calu-6 cell), 333 nM (HCC1937 cell), and 389 nM (MCF-7 cell), respectively.

STF-118804 is a highly specific NAMPT inhibitor.

The water-soluble prodrug of GMX-1778 (CHS-828), which is a potent and specific inhibitor of the NAD(+) biosynthesis enzyme NAMPT with IC50 of <20 nM.

Nampt-IN-5 is a potent and orally active nicotinamide phosphoribosyltransferase (NAMPT) inhibitor. Nampt-IN-5 inhibits CYP3A4 activity and has cellular IC50s of 0.7 nM and 3.9 nM against A2780 and COR-L23, respectively.

GPP78 (CAY10618) is a potent Nampt inhibitor with an IC50 of 3.0 nM for nicotinamide adenine dinucleotide (NAD) depletion. GPP78 is cytotoxic to neuroblastoma cell line SH-SY5Y cells with an IC50 of 3.8 nM by inducing autophagy. GPP78 has anti-cancer and anti-inflammatory effects.

OT-82 is a novel nicotinamide phosphoribosyltransferase (NAMPT) inhibitor with average IC50s of 13.03   nM in non-HP cancer cells and 2.89   nM in HP cancer cells, respectively.

GNI-50 is a potent, selective Nampt inhibitor with enzyme IC50 of 7 nM, A2780 cellular IC50 of 32 nM.GNI-50 showed excellent in vivo antitumor efficacy when dosed orally in an A2780 ovarian tumor xenograft model (TGI of 97% was observed on day 17).

NAMPT activator (NAT-5r) is a potent, small molecule activator of nicotinamide phosphoribosyltransferase (NAMPT) with ITC KD of 180 nM, 3-fold improved activity over NAT.NAMPT activator (NAT-5r) had no effect on NMNAT1 enzyme activity, both NAMPT mutants of K189R and K189A reduced the binding affinity of NAT-5r.NAMPT activator (NAT-5r) treatment significantly enhanced NAD content in NAMPT-WT cells, but not in NAMPT-CRISPR cells.Treatment of NAT-5r at 3 μM concentrations for 4 h induced significant elevation of cellular NAD.NAMPT activator (NAT-5r) induced subsequent metabolic and transcriptional reprogramming, promoted proliferation and maintain the self-renewal of NSCs and protects peripheral sensory neurons from paclitaxel-(PTX) induced damage in mouse model.
