Dimethanesulphonylthioalkanes and analogous compounds were synthesized by the reaction of corresponding sodium thiosulphonate and appropriate dibromide to test the carcinostatic activity compaed with Myleran. It was found that some of these compounds inhibited pronouncedly the growth of the solid tumor produced by Ehrlich ascites carcinoma cells.

Tetramethylene bis(methanethiosulfonate), the S-ester analog of busulfan, was prepared by reacting 1,4-dibromobutane with potassium methanethiosulfonate. 2,4-Dichlorophenyl methanethiosulfonate was prepared by reacting sodium methanesulfinate with 2,4-dichlorobenzenesulfenyl chloride. Neither compound showed antifungal activity against Microsporum audouini or Trichophyton mentagrophytes. Although tetramethylene
Reactivities of mono and difunctional thiosulfonates toward several nucleophilic compounds, such as thiols, amines and the related compounds, were examined. In the result, some chemical behaviors unexpected were found in addition to the reactivity anticipated. Namely, in the reaction with piperazine, aralkyl thiosulfonate afforded aralkyltrisulfide in about 20% yield, without any formation of sulfenamide. Moreover, aromatic thiosulfonate gave a comparable good yield of 1-phenyl-2-arylsulfonylhydrazine in the reaction with phenylhydrazine, in addition to the formation of phenylhydrazinium salt of aromatic sulfinic acid.
