摘要:
The invention concerns the use of a collection of compounds of general formula (I), wherein: n is 0 or 1; p represents an integer between 1 and 6; r represents an integer between 1 and 12; R1 and R'1 represent in particular a hydrogen atom; R2 represents an amino acid side chain or an amino acid derivative; R3 represents a group derived from a carboxylic acid, bearing a basic entity; R4 represents in particular an alkyl group containing 1 to 10 carbon atoms; and A represents a hydrogen atom, a protecting group or a tracing group, in particular a fluorophor, a colouring agent or a quencher, for determining, through binding studies, ligands of receptors whose ligand is unknown or whose ligand useful for carrying out specific affinity binding assays is unknown.

The invention concerns the use of a collection of traceable cationic compounds for determining ligands of a receptor whose ligand is unknown or whose ligand useful for specific affinity binding studies is unknown, said traceable cationic compounds being characterized in that they comprise at least one basic amino acid residue providing the cationic type to said compound and a tracer group, in particular a fluorophor, a colouring agent or a quencher.
摘要:
The invention relates to the cosmetic or pharmaceutical use of a composition containing a derivative of nicotinic or salicylic acid that inhibits chemokines, in order to prevent or treat internal and/or external chronic inflammatory disorders.

The invention concerns an in vitro method for the diagnosis and/or prognosis and/or assessment of the development of a chronic inflammatory lung disease in a patient, using the expression level of the receptor gene coupled to GPR15 G proteins as a biomarker of the disease.
摘要:
The invention concerns a method for isolating an allosteric effector of a receptor, by determining the variation of the dissociation kinetics of the complex formed between said receptor and one of its ligands in the presence of said allosteric effector, as compared to the kinetics dissociation formed between said receptor and said ligand, in the absence of said effector, and/or the amplitude of the linkage formed between said receptor and one of its ligands in the presence of said allosteric effector, as compared to the amplitude of the linkage formed between said receptor and said ligand in the absence of said effector, said receptor and said ligand being involved in at least one biological response in suitable physiological conditions, and the allosteric effector being capable of modulating at least one of the responses, said receptor being marked by at least one fluorescent protein, said ligand being marked by a marker consisting either of a molecule capable of absorbing light emitted by the fluorescent protein, or by a fluorescent substance, said steps for determining kinetics dissociation variation and amplitude variation being carried out by fluorescence energy transfer.

The invention relates to the cosmetic or pharmaceutical use of a composition containing a derivative of theophylline of formula (I) that inhibits chemokines, in order to prevent or treat internal and/or external chronic inflammatory disorders. R represents an alkyl, cycloalkyl or alkenyl group in which at least one -CH 2 - group can be replaced by -O- or substituted by at least one radical selected from among the alkyl, hydroxy and alkoxy radicals.
