The Power of Solid-Phase Peptide Synthesis (SPPS)

Solid-phase peptide synthesis, first pioneered by R. Bruce Merrifield, who was awarded the Nobel Prize in Chemistry in 1984, has become an indispensable tool in chemical laboratories globally. This technique involves the sequential addition of amino acids to a growing peptide chain anchored to an insoluble solid support, typically a resin. The advantages of SPPS are numerous: it simplifies the purification process, as excess reagents and by-products can be washed away from the solid support, and it allows for automation and high-throughput synthesis.

The solid-phase synthesis of peptides for molecules like oxa-lacticin A2 relies on several key steps. These include:
