TETRAPYRROLIC MACROCYCLES AS PHOTODYNAMIC AGENTS

摘要

The invention refers to macrocyclic tetrapirrolic compounds of the family of porphyrins (structure I), chlorins (structure II) and bacteriochlorins (structure III) characterized by the presence of hydrogen or halogen atoms and/or phenyl groups with halogens in the ortho position (with or without hydroxyl groups in the meta position) in positions 5,10,15 and 20 of the macrocycle, and hydrogen or halogen atoms or akyl, vinyl, carboxy, carboxyalkyl, alkoxycarbonyl, alkoxycetoalkyl, alcoxycetoaryl, acetoxy or hydroxyalkyl groups in positions 2,3,7,8,12,13,17 and/or 18.
