Pinealon is a short peptide composed of three amino acids. It is one of a handful of synthetic peptides known as peptide biomodulators because they can interact directly with DNA and alter gene expression. Pinealon has been linked to behavioral modification and is believed to help protect various cells, including neurons, from the effects of hypoxia. By acting directly on the pineal gland, pinealon has been shown to reduce problems with drug metabolism, circadian rhythm disruption, memory, and learning.
