A simple reversed phase HPLC method suitable to study the interactions of a
lkylating agents with DNA is presented in this paper. DNA interaction is ex
pressed as the % DNA peak size exclusion. The effects caused by the antitum
or drugs melphalan, busulphan, and busulpan analogues on DNA were clearly o
bserved through chromatographic data. The synthetic dimethanesulphonates of
2-tetradecyl-1,4-butanediol and 1,2-hexadecanediol were proved more potent
than busulphan.
