Abstract: The present invention is directed to metal-phthalocyanines of general formula (I) to the corresponding conjugates, the processes for their preparation and use in the photodynamic therapy of microbial infections (viral, bacterial and mycotic), tumor, pre-cancerous and proliferative pathologies and/or in the diagnosis, as well as for blood and blood derivatives sterilization.

Abstract: Phthalocyanine analogues having an active group able to link the phthalocyanine t carriers molecules and phthalocyanine to carriers molecules and phthalocyanine analogues as phthalocyanine-carrier conjugates showing enhanced photodynamic properties, red shifted absorption characteristic, all useful for photodynamic therapy, are described. Photosensitizers themselves or the photosensitizers-carriers conjugates are useful compounds either for treatment of various infectious diseases, the in vivo eradication of micro-organisms as well as diseases characterized by cellular hyperproliferation, in particular tumours psoriasis, actinic keratosis, atheromas, endoarterial hyperplasia and prostate hyperplasia. The above compounds can be also useful for blood and blood derivatives sterilization and in vivo/vitro diagnostics.

Abstract: The present invention relates to meta 1-phthalocyanines bearing at least a group containing boron isotopes 11B or 10B, covalently bound to the peripheral positions of meta 1-phthalocyanine nucleus; moreover it refers to the processes for their preparation, the pharmaceutical compositions comprising them and their use for the treatment of neoplastic and dysplastic pathologies.

Abstract: Meso-substituted porphyrins of general formula (I) suitable for the use as photosensitising agents, in particular in photodynamnic therapy, are herein described.

Abstract: The present invention relates to pharmaceutical compositions comprising metal phthalocyanine analogues of formula (I) and metal chelating compounds having a good bioavailability and enhanced photoinactivation properties against Gram negative bacteria; and to their use for in vivolex vivo applications, such as blood and blood derivatives sterilization.

Abstract: The present invention refers to a process for the separation of regioisomeric mixtures of metal phthalocyanines of formula (I), to the regioisomers obtained by this process, and their use as phototherapeutic and photodiagnostic agents.

Abstract: The present invention refers to zinc-phthalocyanines of general formula (I) ##STR1## to processes for their preparation and to their use as phototherapeutic and photodiagnostic agents as free molecules and as conjugates with macromolecular carrier molecules.

Abstract: Conjugates of a carrier molecule and an organic molecule producing singlet oxygen after irradiation are useful in diagnostic and therapeutic applications. The organic molecule is a terthienyl or terfuranyl compound derivatized to react with amino, thiol, or saccharide groups of the carrier molecule. Suitable carrier molecules include antibodies, peptides, haptamers, sugars, and other analogous molecules which direct the organic molecule to a biological target.
