2,8-Dihydroxyadenine, an endogenous metabolite, can induce the generation of urinary crystals and nephrolithiasis. Moreover, 2,8-Dihydroxyadenine serves as a diagnostic tool for detecting adeninephosphoribosyltransferase (APRT) deficiency.
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].
