A short chain of amino acids, chemically manufactured in a laboratory, that is designed to mimic or antagonize the biological action of a naturally occurring endogenous peptide. These molecules are precise therapeutic agents used to selectively modulate specific endocrine or metabolic pathways with high affinity. Synthetic peptides offer the advantage of high purity, predictable stability, and often improved pharmacokinetics compared to their natural counterparts.
Origin
The field of peptide synthesis originated with the pioneering work of Bruce Merrifield in the 1960s, who developed solid-phase peptide synthesis. The term ‘synthetic’ distinguishes these manufactured molecules from those isolated from biological sources. This technology has revolutionized endocrinology and pharmacology by providing highly specific signaling molecules for therapeutic use.
Mechanism
A synthetic peptide acts by binding to a specific cell-surface or intracellular receptor, initiating a signal transduction cascade identical to the natural ligand, or by blocking the receptor to prevent the natural ligand from binding. The precision in their chemical structure allows for targeted action on specific tissues, minimizing systemic side effects. For example, synthetic Growth Hormone-Releasing Peptides stimulate the pituitary to release its own growth hormone, utilizing a targeted secretagogue mechanism.
