摘要:
Multimenic lectins having a β-propeller architecture, formed from monomer modules of approximately 30 to 60 amino acids, in which the binding sites to the glycans are situated on a given side of the proteins and the O-terminus and N-terminus ends of the peptide chains on the other side of the proteins, characterized in that they are formed from 4 to 7 monomer modules, a single, or a plurality of, or all of the adjacent modules being linked to one another by the linkers linking the N-terminus end of one module to the C-terminus end of the adjacent module.
摘要:
The present invention relates to a non covalent molecular structure comprising a carbon nanostructure and a pyrene based glycoconjugate (I) which is linked to the said carbon nanostructure by a non covalent link, the said glycoconjugate (I) having the formula : wherein B is a group which is present on any of the ten carbon atoms of the pyrene structure represented in ( I ) susceptible to bear a substituent, and is represented by the following group : -(CH2) n -CO-NH-A, wherein n is an integer from 1 to 9, A is a group of formula : The present invention also relates to an electronic device comprising the said non covalent molecular structure, and to the use of this device for the detection of a lectin involved in bacterial or viral infections. Thus the invention also relates to a method for detecting the presence of a lectin in a sample to be analysed.
