Thiopeptide (original) (raw)

Thiopeptides (thiazolyl peptides) are a class of peptide antibiotics produced by bacteria. They have antibiotic activity against Gram-positive bacteria, but little or no activity against Gram-negative bacteria. Many of the members of this class show activity against methicillin-resistant Staphylococcus aureus (MRSA) and are therefore subjects of research interest. There are over 100 members of this class known.
