摘要:
The invention concerns the use of quinic, shimic acids and their derivatives for preparing mannose receptor ligands, the resulting ligands and the uses of said ligands, in particular for preparing medicines and, more particularly for preparing vaccines and medicines for vectoring an active principle to target cells expressing the mannose receptor or a receptor related thereto, for transfecting DNA and RNA sequences and numerous other uses in gene therapy, and for preparing laboratory reagents, in particular diagnostic reagents.
摘要:
The invention concerns a functionalised solid support for the synthesis of compounds comprising at least an α-oxoaldehyde function, its method for preparation and its uses, in particular for preparing a bank of organic compounds, a diagnostic reagent, a microtitration plate and a biochip, such as a DNA chip. The invention also concerns a method for the synthesis of organic compounds comprising at least an α-oxoaldehyde function and α-oxoaldehyde peptides obtained by said method.
摘要:
Disclosed are multimeric compounds of K1 domains from the Hepatocyte Growth Factor/Scatter Factor (HGF/SF) being able to induce activation of the tyrosine kinase receptor MET and their uses.
摘要:
Disclosed are proteins derived from the HGF/SF which are able to induce activation of the tyrosine kinase receptor MET and their uses, in particular to promote tissue regeneration. Further disclosed are nucleic acid molecules coding such protein, expression vectors containing such nucleic acid molecule, host cells containing such expression vectors, and related compositions.
摘要:
The invention relates to a device for presenting peptides or proteins which can be used as a polypeptide chip for miniaturized detection of molecules which structurally or functionally complement said polypeptides. Said device consists of a flat support where polypeptides are covalently bound. The link between the polypeptides and the support results from the formation of a semicarbazone link. The semicarbazone link is a specific result of the reaction between polypeptides having an aldehyde or ketone function; and a support functionalized by semicarbazide groupings. The invention also relates to a method for preparing the supports and attaching the polypeptides to these supports in addition to the use of said devices thus obtained as polypeptide chips .
摘要:
The invention relates to the use of a mixture containing at least lipopeptides for vaccine production. Said lipopeptides comprise a peptide compound which has been bound in solution by means of a hydrazone linkage to at least one non-peptidic lipophilic carrier. The invention also relates to native sequences NS3 of the HCV.
摘要:
The invention concerns products comprising a support whereon are fixed nucleic acids and their preparation method and use as DNA support. The invention also concerns functionalised supports, oligonucleotides and DNA's modified in position 5' by a group selected in the group consisting of tartaric acid, serine, threonine, their derivatives and the α-oxoaldehyde group, and the methods for preparing them. The invention further concerns a method for fixing a nucleic acid on a support.
摘要:
The invention concerns a method for coupling a peptide with at least a compound A, of the non-peptide type, bearing a function selected among the group consisting of carboxylic acid functions and alcohol functions. The invention is characterised in that said coupling comprises a step which consists in producing, in solution, a hydrazide bond between said peptide and said compound A. The invention also concerns modified peptides essentially formed by a peptide bound by a hydrazide bond to at least a compound A as defined above, such as a lipid, a sugar, an alcohol or a fluorescent marker, as well as the uses of said modified peptides. The invention further concerns the use of N,N'-tri(Boc)hydrazinoacetic and N,N'-di(Boc)hydrazinoacetic acids to functionalize a peptide with a α-hydrazinoacetic group.
摘要:
The invention concerns lipopeptides comprising at least one auxiliary T epitope, at least one CTL epitope and at least a lipid residue, characterised in that the epitopes and the lipid part, and the epitopes are independently separated by amino acids, called spacers, comprising amino acid chains charged in neutral medium, ensuring affinity for water of said lipopeptides. The invention also concerns the use of said lipopeptides for inducing an immune response against HIV and BHV, papillo mavirus, melanoma p-53, or malaria.
