Thiostreptin is a thiazole-containing peptide antibiotic used in molecular biology applications. The thiostrepton-resistant gene is commonly used as a selective marker for recombinant DNA/plasmid technologies. Thiostrepton inhibits protein synthesis by preventing binding of GTP to 50S ribosomal subunit. Activation of TLR7–9 has been linked to autoimmune diseases such as rheumatoid arthritis, lupus, and psoriasis. Thiostrepton has been shown to be a novel TLR7–9 inhibitor1. Thiostrepton inhbits FoxM1 which ultimately suppresses tumor formation in ovarian cancer cells2.

USE
Thiostrepton has been used as a selectable marker for recombinant Streptomyces cultures as it is one of the cyclic peptides from Steretomyces that is active against gram-positive bacteria. It exhibits antibiotic activity through blockade of ribosome turnover after an elongation step in protein synthesis by inhibiting both the dissociation of elongation factor G (EF-G) from the ribosome and the release of inorganic phosphate from EF-G following GTP hydrolysis. Thiostrepton is also described to show efficacy against cancer cell growth through downregulation of the forkhead box M1 (FOXM1) transcription factor, commonly overexpressed in many malignancies. Thiostrepton is an inhibitor of FOXM1.
