Effect of substituents in chlorin e6 derivatives on the loading efficiency of the photosensitizer into the liposome membrane and their biological activity.

In this work, we incorporated the hydrophobic alkylamide and hydroxyalkylamide derivatives of chlorin e6 into the lipid bilayer of liposomes. We obtained the data on the effectiveness of incorporation of studied compounds and have determined the size of liposomes and their stability when stored in liquid form. We also investigated the bioactivity of chlorin photosensitizers and compared the photodynamic activity of studied compounds in free and liposomal forms.
