Novel photosensitizers for prospective clinical usage and some of their properties

Five novel photosensitizers for photodynamic tumor therapy have been offered as potential drug substances for the prospective clinical usage. A complex of pre-clinic biological studies has been performed, unambiguously demonstrating low systemic toxicity and high photodynamic potential of the substances proposed. The one named 'Photodithazine/Photochlorin I' has already successfully passed a number of clinical test on patients having immergent vital indications.
