title: 1,2-bis(arylsulfonyl)hydrazines. 2. The influence of arylsulfonyl and aralkylsulfonyl substituents on antitumor and alkylating activity.
abstract: Several 1,2-bis(arylsulfonyl)-1-methylhydrazines were synthesized and evaluated for antineoplastic activity against the L1210 leukemia. The most active compound to emerge from this study, 2-[(4-chlorophenyl)sulfonyl]-1-methyl-1-(4-tolylsulfonyl)hydrazine , increased the survival time of tumor-bearing mice by 88%. The alkylating activity of the synthesized analogues and several compounds reported earlier was determined by measuring the absorbance at 540 nm of the alkylated product of 4-(4-nitrobenzyl)pyridine. The results obtained support the concept that the ability to alkylate is a necessary but not a sufficient condition for the expression of antitumor activity by agents of this class.
