Thiostrepton issoluble in chloroform, dichloromethane, dioxane, pyridine, glacial acetic acid, DMF. Practically insoluble in water, the lower alcohols, nonpolar organic solvents, diluted aqeous acids or bases. May be dissolved by methanolic acid or base, but with decomposition. Working solution of 1% in DMSO is unstable and should be freshly prepared and protected  from light.
Appearance: White to off-white powder
Purity: Single stain by TLC.
At least 97% by HPLC.
λmax: No clear UV maxima but shows shoulders at 225, 250, 280 nm
Melting point: Thiostrepton decomposes at 246-256oC
Applications: Thiostrepton is used as a reagent for both positive and negative selection of genes involved in nucleotide metabolism.

Thiostrepton  is highly active against gram-positive bacteria.

In its crude form, Thiostrepton is used in veterinary medicine, in mastitis caused by gram-negative organisms and in dermatologic disorders.
