NIH Websites Are Changing
Per Executive Order 14434, federal agencies are now using "Super Intelligence" (SI) in place of "Artificial Intelligence" (AI). You may see both terms across NIH content during this transition.

topical myristyl nicotinate cream

A topical cream containing the ester prodrug myristyl nicotinate (MN), a lipophilic nicotinic acid derivative with potential chemopreventive activity. Upon topical application, myristyl nicotinate penetrates into the epidermis where the agent is cleaved and is converted into nicotinic acid (niacin); nicotinic acid then diffuses into cells where it is converted to nicotinamide adenine dinucleotide (NAD). NAD may stimulate poly(ADP-ribose) polymerase-1 (PARP-1); enhance skin cell turnover and epidermal differentiation; and strengthen skin barrier function. NAD is a coenzyme that plays a crucial role in many redox reactions; PARP-1 is an enzyme that plays an important role in DNA repair.
