摘要:
A sialic acid derivative of the formula (I), where the symbols are as defined in the description, is suitable for linking with a cargo for regulating metabolic processes, immune reactions, immunizations or desensitizations of the target organism.
摘要:
The invention relates to Siglec inhibitors that have an increased affinity for the receptor molecule. The Siglec inhibitors provided by the invention are preferably selective of a given Siglec molecule. The invention further relates to a method for producing Siglec inhibitors and to a method for increasing the binding selectivity for a given Siglec molecule. The invention also relates to pharmaceutical compositions that contain the Siglec inhibitors and to medical indications for the Siglec inhibitors.
摘要:
The present invention relates to glycoconjugates containing a sialic acid derivate of general formula (I) and wherein the sialic acid derivate of general formula (I) is conjugated to a mono-, di- or oligosaccharide with up to 40 glycosidically linked, optionally branched sugar residues representing furanose and/or pyranose rings, which are linked N- or O-glycosidically to the polypeptide. The sialic derivatives of general formula (I) are useful for producing pharmaceutical compositions for immunosuppression, cell protection, stimulation of hematopoesis regulation of hormonal secretion and hormonal activation.
摘要:
Sialic acid derivatives of the formula (I) in which the symbols have the definitions stated in the description are suitable as medicaments, more particularly for diseases whose course is influenced by Siglec ligands.
摘要:
A process for preparing CMP-activated fluorescence indicator-labelled sialic acids is disclosed. According to the process, a 5-acylamido-9-amino-3,5,9-tridesoxy-.beta.-D-glycero-D-galactonoulosonic acid or 5-aminoacylamido-3,5-didesoxy-.beta.-D-glycero-D-galactonoulosonic acid is reacted with cytidine phosphate in the presence of a CMP-sialic acid synthase which is then reacted with a fluorescing compound to give a CMP-activated fluorescing sialic acid. Also disclosed are novel CMP-activated fluorescing sialic acids.
