Definitions
- This invention relates to polyether-substituted photosensitising compounds and their use in the treatment of tumours.
- Photodynamic therapy involves the administration of a photosensitising compound followed by irradiation of the tissue containing the compound with visible light of a specific wavelength.
- the resulting activated compound with oxygen, forms a reactive radical which causes necrosis of the surrounding tissue.
- tumour localisation can also be used as a diagnostic tool for determination of tumour position, size etc. and thus of the treatment of choice.
- Certain photosensitisers can be used as diagnostic tools, if applicable as sources of detectable fluorescence.
- certain radio-labelled entities can also be incorporated into the tumour localising compounds for the purpose of diagnosis.
- a group of photosensitising compounds have previously been the subject of EP 0 337 601 Al. These compounds are dihydroporphyrins (chlorins) (1) and the corresponding tetrahydro porphyrins (bacteriochlorins) (2) and (3) of the formulae:
- Said substituent groups may be in the same or different positions on their respective phenyl groups and may be free, substituted, or partly substituted, for example with alkyl or acyl groups containing 1 to 4 carbon atoms.
- the nucleus or the phenyl rings may be substituted further, provided pharmacological tolerability, appreciable solubility in water-based pharmacologically acceptable solutions (required so that the drug may be administered intravenously to ensure rapid distribution to the tumour), absorption of light at the red end of the visible spectrum, and take up in cancerous tissue are retained.
- Such further substituted compounds when derivatised as discussed below, are regarded as forms of the compounds of the innovation and included in the scope of the claims herein.
- Any of the compounds may be in the form of their salts at acidic or basic centres, or their metal complexes (e.g. Zn, Ga), or their hydrates or other solvates particularly with lower, e.g. C - C4, aliphatic alcohols.
- the present invention concerns the derivatisation or partial derivatisation of the phenolic hydroxyl groups of compounds of formulae (1), (2) and (3) with polyethylene glycols with or without a linking group, the terminal hydroxyl being etherified or esterified with alkyl or acyl groups, the methyl group being the most preferred.
- the group Y may be a Cj - Cj2 alkyl or acyl group but preferably a methyl group.
- the linking group X may be present or absent, but if present may be of the following alternative forms: -
- the chain length of the terminally substituted polyethylene glycol chains is such as to provide compounds of types (4), (5) and (6) of overall molecular weight of no less than 5,000 D and no more than 20,000 D which is the exclusion limit of the kidneys.
- any free hydroxyl groups may be otherwise derivatised and salts with mineral acids (ie. hydrochlorides, sulphates, etc), metal complexes (ie. with Zn, Ga, etc), hydrates and solvates with lower (C ⁇ - C4) alcohols may be formed. All such forms are included in the claims therein.
- the derivatised dihydro and tetrahydro porphyrin compounds (4), (5) and (6) have the following properties:
- Dosages are such as to give the desired chlorin/bacteriochlorin concentration in the tumour and are between 0.01 mg/kg up to 100 mg/kg depending on the drug.
