    Abstract: Texaphyrin metal complexes having improved functionalization include the addition of electron-donating groups to positions 2, 7, 12, 15, 18 and/or 21 and/or the addition of electron-withdrawing groups to positions 15 and/or 18 of the macrocycle. Electron-donating groups at positions 2, 7, 12, 15, 18 and/or 21 contribute electrons to the aromatic pi system of the macrocycle which stabilizes the metal complex to demetallation and the imine bonds to hydrolysis. The addition of substituents to the 12 and 21 positions of the macrocycle offer steric protection for the imine bonds against possible in vivo enzyme hydrolysis. Electron-withdrawing groups at positions 15 and/or 18 render the macrocycle more readily reduced, i.e. the redox potential is lower and the macrocycle more readily gains an electron to form a radical. Such texaphyrins having a low redox potential and imine bond stabilization are useful in a variety of applications.

    Abstract: The isolated texaphyrin-lipophilic molecule-vesicle complex comprises a vesicle loaded with a texaphyrin-lipophilic molecule conjugate. The vesicle portion of the complex can be a liposome or red blood cell and the lipophilic molecule of the complex is estradiol or cholesterol. An antibody having a binding specificity for a photosensitive texaphyrin molecule is disclosed. The isolated texaphyrin-lipophilic molecule-vesicle complex is used in the production of the antibody and diagnosing or treating ocular disorders such as macular degeneration or neovascularization of the eye. The texaphyrin-lipophilic molecule portion can have the formula I or II wherein: M is a divalent or trivalent cation; R1-4, R7 and R8 are independently H, halo, OH, alkyl, alkenyl, alkynyl, aryl, haloalkyl, nitro, formyl, acyl, hydroxyalkyl, alkoxy, hydroxyalkoxy, hydroxyalkenyl, hydroxyalkynyl, saccharide, carboxy, carboxyalkyl, carboxyamide, carboxyamidealkyl, amino, aminoalkyl, a lipophilic molecule or a linker that is linked to a lipophilic molecule; R6 and R9 are independently are as defined for the groups R1-4, R7 and R8 provided that the halo is not iodide and the haloalkyl is not iodoalkyl; R5 and R10-12 are independently H, alkyl, alkenyl, alkynyl, aryl, hydroxyalkyl, alkoxy, hydroxyalkoxy, hydroxyalkenyl, hydroxyalkynyl, carboxyalkyl, carboxyamide, carboxyamidealkyl, amino, aminoalkyl, a lipophilic molecule or a linker that is linked to a lipophilic molecule; R13 is alkyl, alkenyl, oxyalkyl or hydroxyalkyl having a rotational flexibility around the first bound carbon atom and n is 0 to 5 provided that at least one of R1-12 is a lipophilic molecule or a linker to a lipophilic molecule.
