What is the Origin of Synthetic Peptides?

The creation of synthetic peptides became technically feasible following the development of Solid-Phase Peptide Synthesis (SPPS) by Merrifield in the 1960s. The term synthetic distinguishes them from peptides isolated from biological sources. Their clinical application has expanded rapidly since the late 20th century, with numerous peptide hormones now available as pharmaceutical treatments.

What is the Mechanism of Synthetic Peptides?

The mechanism is based on the principle of molecular mimicry, where the synthetic peptide's amino acid sequence allows it to bind with high affinity to a specific cell-surface receptor, such as a G-protein coupled receptor or a growth factor receptor. This binding event initiates a specific intracellular signaling cascade, either activating (agonist) or blocking (antagonist) the biological effect normally triggered by the endogenous molecule. Their high specificity allows for targeted manipulation of endocrine axes and metabolic pathways.

Synthetic Peptides

Meaning

Synthetic peptides are laboratory-manufactured short chains of amino acids linked by peptide bonds, designed to mimic or modulate the biological actions of naturally occurring signaling molecules, hormones, or growth factors. Unlike small-molecule drugs, these compounds offer high specificity for their target receptors, resulting in precise physiological effects with potentially reduced off-target activity. They represent a significant class of therapeutic agents in hormonal health, metabolic medicine, and longevity research.
