The invention relates to a combination comprising (i) a compound A comprising a mitochondrial targeting group linked to a group capable of releasing hydrogen sulfide or a pharmaceutically acceptable salt thereof or a prodrug thereof, an inhibitor of the thioredoxin antioxidant system or a pharmaceutically acceptable salt thereof or a prodrug thereof, and/or a nitroxide or a pharmaceutically acceptable salt thereof or a prodrug thereof; and(ii) a photosensitizer or photosensitizer precursor;for use in photodynamic therapy.

Combinations of a photosensitizer with a hydrogen sulfide donor, thioredoxin inhibitor or nitroxide for use in photodynamic therapy

The invention relates to a compound comprising a mitochondrial targeting group linked to group capable of releasing hydrogen sulfide, or a pharmaceutically acceptable salt thereof, for use in the treatment of the human or animal body by surgery or therapy. The invention also relates to the use of the compound in the treatment of a plant, and to certain forms of the compound.

Hydrogen sulfide releasing compounds and their use

Compounds for use The invention relates to a combination comprising (i) a compound A comprising a mitochondrial targeting group linked to a group capable of releasing hydrogen sulfide or a pharmaceutically acceptable salt thereof or a prodrug thereof, an inhibitor of the thioredoxin antioxidant system or pharmaceutically acceptable salt thereof or a prodrug thereof, and/or a nitroxide or a pharmaceutically acceptable salt thereof or a prodrug thereof; and (ii) a photosensitizer or photosensitizer precursor; for use in photodynamic therapy.
