Common NameTyrocidine A
DescriptionTyrocidine A is a cyclopeptide antibiotic belonging to the class of linear peptides. Its chemical structure features a cyclic arrangement of amino acids, which contributes to its unique biological properties. Tyrocidine A has been shown to interact with amyloid-β (Aβ) peptides, specifically targeting the hydrophobic region of pyroglutamate-modified Aβ to inhibit its nucleation-aggregation process and its catalytic effect on Aβ aggregation (PMID:39132781 ). Additionally, it interacts with the hydrophobic C-terminus and middle domain of pEAβ3-42, maintaining an unordered conformation that effectively prevents the formation of initial oligomers and halts further aggregation (PMID:...). Furthermore, tyrocidine A is involved in the biosynthetic pathway where it forms complexes with tyrocidine synthetase C (TycC)-TE, facilitated by a linear peptide variant, enhancing the efficiency of the synthesis process (PMID:37423887 ). These interactions highlight the multifaceted role of tyrocidine A in both its chemical and biological contexts, underscoring its potential as a therapeutic agent against amyloid-related pathologies.
