Syntetiaa

Syntetiaa is a class of synthetic amino acid analogs developed for biochemical research and pharmaceutical development. Unlike the 20 standard amino acids, Syntetiaa molecules are designed to expand chemical diversity in proteins and peptides. The name blends synthetic and amino acid (aa).

Chemically, Syntetiaa encompasses a broad range of backbones and side chains, including halogenated, bulky, or functionalized groups. They can be produced by total chemical synthesis or biosynthetic routes using engineered organisms that incorporate noncanonical amino acids via orthogonal tRNA synthetase/tRNA pairs. Syntetiaa are typically incorporated into peptides or proteins using in vitro translation systems or recombinant expression.

Applications include studying protein folding and interactions, introducing probes for imaging, enabling site-specific conjugation, and creating proteins with unusual properties for materials or therapeutics.

Regulatory and safety aspects: as nonstandard amino acids, they are mainly used in laboratories under appropriate controls; purity, enantiomeric selectivity, and potential toxicity are important considerations. Research status: Syntetiaa have been reported in peer-reviewed literature since the late 1990s and are increasingly used in gene- and protein-engineering workflows; adoption varies by field and institution.
