description
The non-proteinogenic amino acid Kynurenine (Kyn) is a known oxidation product of tryptophan. In cells, this process may be caused by reactive oxygen species (ROS). Such changes can lead to altered protein structure and function causing either degradation or accumulation/aggregation linked to the pathogenesis of several diseases. Our Fmoc-protected Kyn allows to synthesize model peptides for functional and structural studies.
Besides, Kyn is also part of Daptomycin (trade name Cubicin), an effective lipopeptide for the treatment of infections caused by antibiotic-resistant gram-positive pathogens.
