Abstract

The invention relates to (a) streptonigrin monoxime, its mono-alkyl and trimethyl ester and the dimethylsulphate quaternary salt of the trimethyl ester, (b) isopropylidene azastreptonigrin, its mono-alkyl and trimethyl ester and the dimethylsulphate quaternary salt of the trimethylester, (c) dihydroazastreptonigrin, (d) azastreptonigrin and complexes of (a), (b), (c) and (d) with polyvalent metal ions, e.g. Ca, Cd, Ce, Cr, Cu, Fe, Ni and Zn. Streptonigrin monoxime is obtained by reacting streptonigrin with hydroxylamine in a solvent such as pyridine. Monoalkyl esters are produced by reacting the oxime with an alcohol and an acid catalyst especially a Lewis acid. The trimethyl ester is produced by reaction with diazomethane. The dimethylsulphate quaternary ammonium salt of the trimethyl ester is produced by treating the oxime with dimethylsulphate and K2CO3 in acetone solution. Isopropylidene azastreptonigrin is prepared by treating dihydroazastreptonigrin with acetone in the presence of air oxidation. Catalyctic or chemical reduction of the monoxime produces the unstable dihydroazastreptonigrin which oxidizes in air or oxygen to azastreptonigrin. Streptonigrin has the formula <FORM:1043858/C2/1> Streptonigrin monoxime has the formula <FORM:1043858/C2/2> wherein X is the C and D rings above.ALSO:A pharmaceutical composition for the treatment of tumours in man and animals comprises streptonigrin monoxime or isopropylindene azastreptonigrin (antibiotics) and a carrier for oral or parenteral use. Optional ingredients are other antibiotics, hypnotics, analgesics, local anaesthetics and carcinostatic agents e.g. nitrogen mustard type 6-mercaptopurine, 8-azaguanine, urethane, 6-diazo-5-oxo-1-norleucine, azaserine, triethylenemelamine mitomycin C, triethylenephosphoramide, 1, 4-dimethyl-sulphonyloxybutane and carcinostatic folic acid analogues.
