Siomycin A (Mutabilycin, Sporangiomycin, Antibiotic 6741
Artikelnummer: S1013-86W.500
Siomycin is a macrocyclic antibiotic with potent and selective antibacterial activity discovered in 1969. Recently, siomycin was discovered to be a potent inhibitor of the oncogenic transcription factor-forkhead box M1, FoxM1 (previously known as HFH-11B, Trident, WIN or MPP2). The reduced transcription activity was...

Thiostrepton (Bryamycin, Thiactin, Alaninamide, Antibiot
Artikelnummer: T3792-12.5
Thiostrepton is a macrocyclic antibiotic incorporating thiazoles and other atypical amino acids. Patented in 1961, thiostrepton has been used as an antibiotic and acts by binding to ribosomes to prevent the binding of the EF-G elongation factor and GTP to the 50S riobsomal subunit. Thiostrepton is an inducer of...
