Melanotropin ligands for skin care

摘要

A melanocortin 1 receptor (MC1R) peptide ligand-elastic vesicle complex. The MC1R peptide ligand is modified by coupling the MC1R ligand to a functionality or linker, such as a click functionality, for conjugation to a surface or agent. The modified MC1R peptide ligand can be coupled, e.g., via a click reaction with a complementary click functionality attached, to a moiety to form an MC1R-targeted agent. Drugs, contrast agents, polymers, particles, micelles, elastic vesicles, surfaces of larger structures, or other moieties can be targeted to the MC1R. The MC1R peptide ligand-elastic vesicle complex is prepared as a topical formulation.
