GNE-618 is a potent and orally active inhibitor of nicotinamide phosphoribosyltransferase (IC50: 6 nM). GNE-618 depletes NAD levels and induces tumor cell death. It has anti-tumor activity.
Nampt activator-4, a positive allosteric modulator (N-PAM) of nicotinamide phosphoribosyltransferase (NAMPT), has an EC50 of 0.058 μM and can enhance nicotinamide adenine dinucleotide (NAD+) levels in cells [1].
