Thiostrepton was discovered by Donovick et al. who described its antibacterial properties in 1955.Dorothy Crowfoot Hodgkin solved the structure of thiostrepton in 1970.A total synthesis of Thiostrepton was completed by K.C. Nicolaou, et al. in 1995.
Thiostrepton (CAS NO.1393-48-2) has been used in veterinary medicine in mastitis caused by gram-negative organisms and in dermatologic disorders. It is mostly used in complex ointments containing neomycin, nystatin, Thiostrepton and topical steroids. It is also active against gram-positive bacteria. It is notable that ointments for human usage contain neomycin, nystatin, and topical steroids, but no Thiostrepton.Recently, Thiostrepton has been reported to exhibit activity against breast cancer cells through targeting the transcription factor forkhead box M1.Thiostrepton is used in molecular biology as a reagent for both positive and negative selection of genes involved in nucleotide metabolism.
