Novel fluorinated alkenylene diamine derivatives are inhibitors of decarboxylase enzymes involved in polyamine formation and have the following general Formula I:-wherein:-
Ra represents hydrogen or R2, where R2 is as defined below;
Rb represents hydrogen or, when Ra is hydrogen, R2, where R2 is as defined below;
Rc represents hydrogen or -COR3, where R3 is as defined below;

each R2 independently represents C2-C5 alkylcarbonyl, phenylcarbonyl, phenyl-(C1-C4 alkyl) carbonyl, or an aminocarboxylic acid residue derived by removal of an hydroxy group from a carboxy moiety of an L-aminocarboxylic acid;
R3 represents hydroxy, or, when Ra and Rb are both hydrogen, C1-C8 alkoxy, -NR4R5, where R4 and R5 are as defined below, or an aminocarboxylic acid residue derived by removal of a hydrogen atom from the amino moiety of an L-aminocarboxylic acid;
R4 and Rs independently represent hydrogen or C1-C4 alkyl; and
p represents 1 or 2.
