Secondary disulfonamides and secondary tetrasulfondiamides as proposed new biological alkylating agents

Secondary disulfonamides and secondary tetrasulfondiamides were prepared for antineoplastic activity testing. For the disulfonamides, one alkyl series (n-butyl), three aralkyl series (benzyl, phenethyl, and phenpropyl), and one diaralkyl series (diphenpropyl) were prepared. Two series of tetrasulfondiamides were made from diamines, one in which the central methylene chain was varied from four to six and another using the tetrasubstituted sulfonyl derivative of xylylenediamine. Thirteen final compounds were synthesized. Ten of these compounds and four intermediates have not been reported previously. Preliminary screening results for the final compounds are given.
