Thiostrepton
Antibiotic and FOXM1 inhibitor / Novel cyclopeptide antibiotic. Blocks bacterial protein synthesis by inhibition of mRNA-tRNA translocation by GTPase elongation factor G (EF-G), EF-TU(GTP)-catalyzed aa-tRNA delivery as well as the activity of initiation factor-1 (IF-2)1-2. Displays antitumor activity. Induces apoptosis and cell cycle arrest in various tumor cells via downregulation of FOXM1 expression3.
