The invention provides mitochondria-targeted chemiluminescent agents and their use in methods of photodynamic therapy (PDT). In particular, the invention provides compounds of general formula (I), and their pharmaceutically acceptable salts: (I) in which A represents a chemiluminescent moiety; each L, which may be the same or different, is either a direct bond or a linker; each B, which may be the same or different, represents a mitotropic moiety; n is an integer from 1 to 3, preferably 1; and x is an integer from 1 to 3, preferably 1. Such compounds find particular use in the treatment of deeply-sited tumours, e.g. glioblastoma multiforme (GBM), when used in combination with a photosensitizer or photosensitizer precursor.

Method of photodynamic therapy

The present invention relates to compositions and methods for cancer therapy, including but not limited to, therapies that utilize cancer biomarkers. In particular, the present invention relates to compositions and methods for the prediction of a subject's response to cancer therapies.

Diagnosis and treatment of cancer

The present invention relates to novel chitosan-based conjugates, e.g. nanocarriers, comprising a derivative of the biocompatible polymer chitosan conjugated to a photosensitizing agent, and uses thereof in photochemical internalization (PCI) and photodynamic therapy (PDT). The invention also relates to the use of the novel conjugates of the invention in treatment or prevention of diseases, particularly cancer, and for vaccination purposes.

Conjugate of a photosensitiser and chitosan and uses thereof

The present invention provides a method of stimulating an immune response to an antigenic molecule, by contacting a cell with the antigenic molecule and with a photosensitizing agent, irradiating the cell, and thereby presenting the antigenic molecule, or part thereof, on the surface of said cell and stimulating an immune response.

Method of stimulating an immune response

The present invention relates to a method for enhancing the activity of kinase inhibitors in target cells, and more specifically for enhancing the activity of tyrosine kinase inhibitors (TKIs), said method comprising contacting a cell with a kinase inhibitor and a photosensitizing agent and irradiating said cell with light of a wavelength effective to activate the photosensitizing agent, and to the use of this method for enhancing the effects of kinase inhibitors or kinase inhibitor-based drugs in particular to achieve cell death, for example, in cancer treatment and other diseases or conditions in which kinase inhibitors, such as TKIs, have a beneficial effect.

Photochemical internalisation of kinase inhibitors

The present invention provides a method of expressing an antigenic molecule or a part thereof on the surface of an antigen-presenting cell, said method comprising introducing a molecule into the cell cytosol by photochemical internalisation, wherein said molecule, or a part thereof, is subsequently presented on the surface of said cell. Methods of vaccination comprising this method, together with compositions comprising said cells and uses involving said cells expressing antigenic molecules are also provided.

Method of vaccination

The present invention provides photosensitizing agents obtained by reducing a single double bond in the porphyrin macrocycle of a sulphonated meso-tetraphenylporphyrin, preferably a disulphonated meso-tetraphenylporphyrin such as TPPS. The resulting sulphonated meso-tetraphenyl chlorins include compounds of formula I: (wherein The compounds of the invention and their pharmaceutically acceptable salts find particular use as photosensitizing agents in the photochemical internalization of molecules and in photodynamic therapy.

Compound

The present invention provides a method for introducing a molecule into the cytosol of a cell in which the cell is contacted with a photosensitising agent, the cell is irradiated with light of a wavelength effective to activate the photosensitising agent and, substantially at the same time or after the irradiation, the cell is contacted with the molecule to be introduced, particularly for use in cancer treatment, gene therapy and vaccination.

Photochemical internalization for delivery of molecules into the cytosol

The present invention provides photosensitizing agents obtained by reducing a single double bond in the porphyrin macrocycle of a sulphonated meso-tetraphenylporphyrin, preferably a disulphonated meso-tetraphenylporphyrin such as TPPS. The resulting sulphonated meso-tetraphenyl chlorins include compounds of formula (I) (wherein X is &#x2014;SOH; n, p, q and r are each independently 0 or 1; and the sum of n, p, q and r is an integer from 1 to 4, preferably at least 2, e.g. 2 or 4) isomers and isomer mixtures thereof. The compounds of the invention and their pharmaceutically acceptable salts find particular use as photosensitizing agents in the photochemical internalization of molecules and in photodynamic therapy. 

Sulphonated meso-tetraphenyl chlorins

A method for introducing a molecule into the cytosol of a cell in which the cell is contacted with a photosensitizing agent, the cell is irradiated with light of a wavelength effective to activate the photosensitizing agent and, substantially at the same time or after the irradiation, the cell is contacted with the molecule to be introduced, particularly for use in cancer treatment, gene therapy and vaccination.

Photochemical internalization for virus-mediated molecule delivery into the cyosol

The present invention provides a method for introducing a molecule into the cytosol of a cell in which the cell is contacted with a photosentistising agent, the cell is irradiated with light of a wavelength effective to activate the photosentisitising agent and, substantially at the same time or after the irradiation, the cell is contacted with the molecule to be introduced, particularly for use in cancer treatment, gene therapy and vaccination.

The present invention relates to a method for introducing molecules in cells by disrupting endosomal and lysosomal membranes using photodynamic treatment, without killing the majority of the cells by the photodynamic treatment. More particularly, this invention includes a method for transferring DNA and/or RNA, such as genes, to cells by photochemically inducing the disruption of endosomes and lysosomes.
