Melanotan I, also known as afamelanotide, is a synthetic linear peptide analogue of α-melanocyte-stimulating hormone (α-MSH). It is composed of 13 amino acids and was engineered to improve molecular stability and receptor selectivity in experimental research models.
In laboratory settings, Melanotan I is studied for its interaction with melanocortin receptors (MC receptors) involved in pigmentation signaling and related neuroendocrine pathways. Compared to cyclic melanocortin peptides, its linear structure results in distinct pharmacological and stability characteristics that are of interest in controlled research environments.
