The synthesis of enantiomerically pure unsaturated long chain 1,2-diamines
and amino alcohols was carried out starting from the corresponding non-natu
ral a-amino acids. The in vitro cytotoxicity of the compounds prepared was
evaluated against six solid tumor cell lines (A2780, H322, LL, WiDr, C2610
and UMSCC-22B). Free 1,2-diamines proved to be the most active compounds ex
hibiting IC50 values between 2.0 mM and 3.3 mM.
