摘要:
The invention provides the use of an optionally hydroxy-protected 4-hydroxyo or hydroperoxy-3,5-dioxopyrazolidine or an equivalent wherein a pyrazolidine ring attached oxygen is replaced by a sulphur, or a physiologically acceptable salt thereof, for the manufacture of a medicament for use in therapy or prophylaxis. Additionally, the invention provides a method of combating HIV infection which comprises administering to an HIV-infected patient a T-lymphocyte growth suppressing agent, preferably a pyrazolidinol, in an amount sufficient to suppress T-lymphocyte growth in said patient for a period sufficient to reduce the T-lymphocyte concentration in lymph nodes in said patient by at least 25%, said administration being repeated at intervals of at least 3 months.

The invention provides the use of a photosensitizer which is 5-aminolevulinic acid (5-ALA) or a derivative (e.g. an ester) of 5-ALA, or a pharmaceutically acceptable salt thereof, in the manufacture of a composition for use in methods of photodynamic therapy (PDT) on an animal, wherein said PDT comprises: (a) administering to said animal a composition comprising said photosensitizer; and (b) photoactivating said photosensitizer, and wherein side-effects (e.g. pain and/or erythema) of said PDT are prevented or reduced by use of one or more of (i)-(iv): (i) said composition comprises said photosensitizer in a concentration of less than 10% wt (e.g. 0.5 to 8% wt), (ii) said composition is administered for less than 2 hours (e.g. 30 minutes to 90 minutes) prior to said photoactivation, (iii) said photoactivation is carried out with a light source having a fluence rate of less than 50 mW/cm2 (e.g. 5 to 40 mW/cm2), (iv) said photoactivation is carried out with sunlight. Preferably, side-effects of PDT are prevented or reduced by using (iii) or (iv) in combination with (i) and/or (ii).
摘要:
This invention relates to antioxidants and combinations of antioxidants used to prevent oxidation of pharmaceutical and nutraceutical products in the form of powders, granulates, tablets, emulsions, gels and the like comprising one or more fatty acids and/or fatty acid derivatives and, optionally, at least one carbohydrate carrier alone or together with vitamins, minerals and/or pharmaceuticals. In particular, the invention concerns the use of antioxidants to reduce oxidation of powders, tablets, gels and emulsions comprising high concentrations and high doses of omega-3 fatty acids or derivatives thereof.
摘要:
The present invention relates to compounds having 5-hydroxytryptamine receptor modulating activity, in particular compounds having an acidic moiety held distant from the 5-HT pharmacophore by a rigid linker group, to compositions containing such compounds and methods of treatment using them. Such compounds have an increased affinity for the 5-HT receptor and a reduced hERG effect. Certain compounds of the invention further exhibit an angiotensin II receptor modulating activity. Claimed are compounds of formula (I): HT-L-A. HT is a 5-HT receptor modulating moiety containing a basic nitrogen atom; A is an acid moiety; L is a linker moiety.
摘要:
The invention provides compounds for use in photochemotherapy or diagnosis, said compounds being branched alkyl esters or substituted alkyl esters of 5-aminolevulinic acid, or derivatives or pharmaceutically acceptable salts thereof. In particular, the invention provides compounds of formula (I): R22N—CH2COCH2CH2CO—OR1 (wherein R1 represents an optionally substituted branched alkyl (e.g. C5-30 alkyl) group, or a substituted alkyl group; R2, each of which may be the same or different, represents a hydrogen atom or an optionally substituted alkyl group, preferably a group R1; wherein said substituents are selected from hydroxy, alkoxy, acyloxy, alkoxycarbonyloxy, amino, aryl, nitro, oxo, fluoro, —SR3, —NR32 and PR32 groups, and each alkyl group is optionally interrupted by one or more O—, —NR3—, —S— or —PR3— groups; and R3 represents a hydrogen atom or a C1-6 alkyl group) and salts thereof for us in diagnosis and photochemotherapy of disorders of abnormalities of external or internal surfaces of the body, and products and kits for performing the invention.
摘要:
The invention provides a composition of matter of the formula (I): V-L-R, where V is a vector moiety having affinity for an angiogenesis-related endothelias cell receptor, L is a linker moiety or a bond and R is a detectable moiety, characterised in that V is a non-peptidic organic group, or V is peptidic and R is a macromolecular or particulate species providing a multiplicity of labels detectable in in vivo imaging.
摘要:
The invention provides contrast agents for optical imaging of prostate cancer in patients. The contrast agents may be used in diagnosis of prostate cancer, for follow up of progress in disease development, for follow up of treatment of prostate cancer and for surgical guidance. Further, the invention provides methods for optical imaging of prostate cancer in patients.
摘要:
The invention relates to ultrasound contrast agents comprising vesicles comprising a protein capable of formation of gas-containing vesicles, wherein the vesicles contain gas which comprises sulphur hexafluoride or a low molecular weight fluorinated hydrocarbon. These contrast agents exhibit stability in vivo upon administration so as to permit ultrasound visualization while allowing rapid subsequent elimination from the system.
