first hybrids of carnosine and 8‐hydroxyquinoline, carnoquinolines (CarHQs), which combine the properties of the dipeptide with those of 8‐hydroxyquinoline, are reported. CarHQs and their copper complexes were characterized through several techniques, such as ESI‐MS and NMR, UV/Vis, and circular dichroism spectroscopy. CarHQs can modulate self‐ and copper‐induced amyloid‐β aggregation. These hybrids combine
that the glycoconjugation protects the dipeptide moiety from carnosinase hydrolysis, thus potentially improving the availability of carnosine. The copper(II) binding properties of all the new synthesized compounds were investigated by spectroscopic (UV–Visible and circular dichroism) and ESI-MS studies. Particularly, the new family of amide derivatives that are not significantly hydrolyzed by carnosinase
