Abstract:
The subject of the present invention is a microplate, or microtitration plate, having an invagination consisting of a continuous peripheral channel making it possible to add thereto, in a single delivery step, a liquid acting as "evaporation curtain". The invention also relates to a device comprising such a microplate, to a manufacturing process and to the use of such a microplate.
Abstract:
The present invention relates to a batch method for impregnating a nonporous polymer pharmaceutical carrier with an active substance, characterised in that said method includes the following consecutive steps: a) mixing the active substance and the nonporous polymer pharmaceutical carrier, the pharmaceutical carrier being in a solid form and insoluble in supercritical CO2 and not being non-crosslinked polyvinylpyrrolidone; b) performing a step of molecular diffusion in the absence of water by contacting, in a static mode without agitation, the mixture obtained in step a) with supercritical CO2 at a pressure of 80 to 170 bars, at a temperature of 31 to 90°C for 1 to 6 hours; c) recovering the polymer pharmaceutical carrier impregnated with the active substance obtained in step b), the impregnated pharmaceutical carrier being nonporous and being in a solid form and the active substance being in an amorphous form, the method being implemented in the absence of an additional solvent. The invention further relates to a polymer pharmaceutical carrier in a nonporous solid form impregnated with an active substance characterised in that said carrier can be obtained by the method according to the present invention, in that the active substance is in an amorphous form and is water-soluble, and in that the polymer pharmaceutical carrier is not non-crosslinked polyvinylpyrrolidone and is insoluble in supercritical CO2.

Abstract:
The invention relates to a novel method for preparing (poly)aminoalkylaminoacetamide derivatives of epipodophyllotoxin and the salts thereof. The invention is characterised in that it includes a step comprising the peptide coupling of 4 amino 4' demethylepipodophyllotoxin to an amine reactant containing protective groups.
Abstract:
The present invention relates to the use of at least one antibody, or a functional fragment thereof, capable of binding to the CD151 protein and thus of inhibiting tumour growth, for the preparation of a medicament for use in the treatment of cancer. The invention also relates to a composition for the treatment of cancer, comprising, as active ingredient, at least one anti-CD151 antibody, or a functional fragment thereof, capable of binding to the CD151 protein and/or of inhibiting the development of primary tumours and/or of inhibiting its metastasis-promoting activity, wherein said antibodies may consist of the TS151 and/or TS151r antibodies.
Abstract:
The invention concerns 3,5-dioxo-(2H,4H)-1,2,4-triazine derivatives of general formula (I), wherein: R 1 and R 2 , identical or different, represent a branched or linear C 1 -C 7 alkyl or alkenyl radical, a C 1 -C 6 alkyl radical substituted by groups such as trifluoromethyl, C 5 -C 6 cycloalkyl, nitrile, C 1 -C 4 alkoxycarbonylvinyl, hydroxycarbonylvinyl, C 1 -C 4 alkoxycarbonyl, carboxylate, benzyloxy or phenyl (for which the phenyl ring is optionally substituted by one or more groups such as C 1 -C 4 alkoyl, C 1 -C 4 alkoxy, nitro, halogen, trifluoromethyl); YR 3 represents oxygen or NR 3 for which R3 represents hydrogen, a linear or branched C 1 -C 7 alkyl or alkenyl radical, a C 1 -C 6 alkyl radical substituted by groups such as trifluoromethyl or phenyl (for which the phenyl ring is optionally substituted by one or more groups such as C 1 -C 4 alkoyl, C 1 -C 4 alkoxy, nitro, halogen, trifluoromethyl); Z represents an oxygen atom or a carbon atom capable of being bound to the ortho, meta or para positions of the phenyl group of formula I; n can be 0 to 5 when Z=C or 2 to 4 when Z=O; X represents oxygen or sulphur; R 4 , R 5 , R 6 , R 7 and R 8 represent hydrogen or fluorine; R 9 , R 10 and R 11 represent hydrogen or a linear or branched C 1 -C 5 alkyl group as well as the pharmaceutically acceptable base addition salts, and the various enantiomers of compounds having asymmetric carbons, and their mixtures in all proportions including in particular the racemic mixtures.
Abstract:
The invention concerns the use of a zwitterion-type detergent, in particular ZW 3-14 (N-tetradecyl-N, N-dimethyl-amino)-propane-1-sulphonate), for preparing a pharmaceutical composition for nasal delivery to induce or enhance immunity of a mammal to an antigen or a hapten associated therewith. The invention also concerns the use of said zwiterrion-type detergents in pharmaceutical compositions, in particular, vaccine compositions capable of further containing a carrier and adjuvant compound, for prophylactic and therapeutic treatment of infections or tumours. The invention further concerns said pharmaceutical compositions.
Abstract:
The invention concerns a novel method for preparing a polypeptide soluble in an aqueous solvent in the absence of detergent, and polypeptides obtainable by said method. The invention also concerns the use of said polypeptides, in particular for preparing medicines or vaccines, for fighting against bacterial and viral infections or cancers.
Abstract:
The invention concerns the identification and the characterisation of a novel gene expressed in tumour cells and involved in the regulation of the immune response, the cloning and the characterisation of its cDNA and the corresponding polypeptides. The invention also concerns vectors containing a nucleic acid coding for said gene, cells transformed by said vectors and diagnostic methods and selection methods of a chemical or biological compound capable of directly or indirectly interacting with a nucleic acid or a polypeptide of the invention.
