Therapeutic Peptides are short chains of amino acids that function as signaling molecules in the body, which are synthesized and administered for the purpose of treating diseases or enhancing physiological function. Unlike large protein drugs, peptides are generally small enough to be highly specific in their action, binding to particular receptors or targets to modulate cellular pathways. They represent a rapidly evolving class of pharmaceutical agents in clinical practice, utilized for their high efficacy and generally favorable safety profile.
Origin
The term is a compound of “therapeutic,” relating to the healing of disease, and “peptides,” referring to the class of small protein-like molecules they belong to, derived from the Greek peptos, meaning “digested.” This nomenclature reflects their use as medicinal agents that leverage the body’s natural signaling mechanisms.
Mechanism
These peptides exert their effects by mimicking or antagonizing the action of endogenous signaling molecules, such as hormones, growth factors, or neurotransmitters. For example, growth hormone-releasing peptides bind to ghrelin receptors to stimulate pituitary GH secretion, while other peptides may act as agonists for specific immune or metabolic receptors. Their mechanism is defined by precise receptor binding and the subsequent initiation of specific intracellular signaling cascades, offering targeted physiological control.
