Synthesis and in vitro cytotoxicity of novel long chain busulphan analogues

Two novel long chain alkanediol dimethanesulphonates, analogues of busulphan, were synthesized. Their in vitro cytotoxicity was evaluated against six solid tumor cell lines (A2780, H322, LL, WiDr, C26-10 and UMSCC-22B). 2-Tetradecylbutane-1,4-diol dimethanesulphonate was proved to be the most active compound exhibiting IC50 values between 20.82 and 26.36 μM.
