WebZn(II) binding by the dipyridine-containing macrocycles L1-L3 has been analyzed by means of potentiometric measurements in aqueous solutions. These ligands contain one (L1, L2) or two (L3) 2,2'-dipyridine units as an integral part of a polyamine macrocyclic framework having different dimensions and numbers of nitrogen donors. Depending on the number … WebNicotinamide adenine dinucleotide (NAD+) can enhance the mitochondrial function and restrain the following inflammation, but it is hardly delivered and lacks renal targeting ability. To address these problems, we herein use an ultra-small Fe3O4nanoparticle as a carrier to deliver nicotinamide mononucleotide (NMN), a precursor of NAD+.
