Azide Solid Support for 3′-Conjugation of Oligonucleotides and Their Circularization by Click Chemistry
摘要:
A solid support bearing an azido linker was used to synthesize a 3'-azido-alkyl-oligonucleotide by phosphoramidite chemistry. The resulting oligonucleotide was either conjugated by 1,3-dipolar cycloaddition on solid support or in solution with mannose-propargyl derivative and in solution with dansyl propargyl. Besides, after introduction of an alkyne function at the 5'-end, the resulting oligonucleotide hearing both 3'-azide and 5'-alkyne functions was circularized.

Method for the synthesis of nucleotide derivatives wherein molecules of interest are grafted on the oligonucleotide with the help of a “click chemistry” reaction between an azide function on the molecule of interest and an alkyne function on the oligonucleotide, or between an alkyne function on the molecule of interest and an azide function on the oligonucleotide.
Intermediate molecules, notably alkyne functionalized oligonucleotides, grafted oligonucleotides, azide functionalized oligonucleotides, oligonucleotide micro arrays containing them and the use of those grafted oligonucleotides for biological investigation and for cell targeting.

Synthesis of branched-phosphodiester and mannose-centered fucosylated glycoclusters and their binding studies with Burkholderia ambifaria lectin (BambL)
their ability to bind to Burkholderia ambifaria Lectin (BambL). Bindingevaluation was performed through inhibition of hemagglutination (HIA), surface plasmon resonance (SPR) and isothermal titration microcalorimetry (ITC). All fucosylated glycoclusters exhibited a higher affinity to BambL than methyl α-L-fucoside. A dissociation constant of 43 nM was observed for the fucocluster exhibiting four residues
