They can act as signaling molecules, transmitting messages between cells and coordinating various physiological functions

This macrocyclic constraint restricts conformational flexibility, contributing to the extended biological activity duration observed versus native -MSH

2 Upon application to the skin, DHA undergoes a Maillard reaction: a nonenzymatic chemical reaction between the carbonyl group of a reducing sugar and the free amino group of amino acids or proteins, forming brown-colored polymers known as melanoidins

The integration of other therapies, such as immunotherapy or radiation, may enhance the effectiveness of the treatment and improve long-term survival rates

Melanotan 1 is highly selective for MC1R, the receptor on pigment cells (melanocytes) that controls eumelanin, the brown pigment behind a tan
