both biologically active ( tpa , 12-o-tetradecanoylphorbol-13-acetate , pdd , phorbol-12,13-didecanoate ) and inactive ( 4 alpha-pdd , 4 alpha-phorbol-12,13-didecanoate ) phorbol esters lowered the temperature required to cause a fall in fluorescence polarization of a fluorescent probe inserted in the lipid matrix of the dmpc or dppc liposomes and facilitated the process of calcium exchange-diffusion in dppc liposomes containing the ionophore a23187 .
