  • Patent number: 11484593
    Abstract: This invention relates to atroipsomers of reduced tetraphenylporphyrin derivatives with halogen atoms (F, Cl, Br) in the ortho positions of the phenyl groups, particularly halogenated tetraphenylchlorins and halogenated tetraphenylbacteriochlorins, which can be used in photodynamic therapy. According to the formulae of the invention, the ortho-phenyl substituents X1, X2, X3, X4, X5, X6, X7 and X8 may be identical or different and represent halogen atoms or hydrogen atoms, provided that at least all of X2, X4, X6 and X8 are halogens, and the meta-phenyl substituents R1, R2, R3 and R4 are independently chosen from —OH, —OR or —SO2R?, where R? are each independently chosen from —Cl, —OH, -aminoacid, —OR, —NHR, or —NR2, where R are alkyl of 1 to 12 carbon atoms or R2 represents cycloalkyl with 2 to 12 carbon atoms. The atropisomers of this invention have the majority of the substituents R1, R2, R3 and R4 on the same side of the plane defined by the macrocycle.

  • Publication number: 20220259334
    Abstract: The present invention describes methods for obtaining functionalized polymeric surfaces (MPn-PSm) from polymers or copolymers with appropriate functionalizations (X), which can be a halogen of a leaving group, such as polyvinyl chloride (MP1) and (chloromethyl)polystyrene-Merrifield (MP2), and curcumin photosensitizers (PS1), meso-tetra(aryl)porphyrins, chlorins or bacteriochlorins halogenated and functionalized with nucleophilic groups (PS2), in particular including P2 of the type meso-imidazoyl-porphyrins, chlorins or bacteriochlorins (PS3). The structures of all the photosensitizers in the present application incorporate a functional group (Y), which is a OH, SH or NH2nucleophile. The application also describes the covalent bonding process of the photosensitizers PS1-PS3 to the functional polymeric materials MP1-MP2 by means of a nucleophilic substitution reaction to prepare the MPn-Psm products.

  • Patent number: 10450322
    Abstract: The present invention relates to carboxamide halogenated porphyrin derivatives, in particular bacteriochlorin or chlorin, of formula (I) use of the same or a pharmaceutically acceptable salt thereof in photodynamic therapy, where the derivatives are able to detect and exhibit the presence of hyperproliferative disorders and, in the presence of an adequate lighting, to treat the same. The present invention also describes a pharmaceutical composition having the carboxamide halogenated porphyrin derivatives, in particular bacteria-chlorin or chlorin, of Formula (I) or a pharmaceutically acceptable salt thereof, for the treatment of cancer and/or microbial and/or viral infections, in humans or animals.

  • Patent number: 9670217
    Abstract: The disclosed subject matter includes methods of preparation, properties, pharmaceutical compositions and methods of therapy of sulfonated chlorins and bacteriochlorins designed for the photodynamic therapy (PDT) of hyperproliferative tissues such as tumors, hyperproliferative blood vessels and other disorders or abnormalies that are responsive to PDT. In particular, the economical large-scale synthesis of stable chlorins and bacteriochlorins is described. Their properties were tailored to meet those of ideal photosensitizers for PDT. In another embodiment, pharmaceutical compositions and methods of therapy for systemic administration are provided. In a further embodiment, pharmaceutical compositions and methods of therapy for topical administration are also provided. Further provided is a method of labeling a target tissue and providing an image of that tissue by fluorescence of magnetic resonance imaging.
