标 题:Methods for H-phosphonate synthesis of mono- and oligonucleotides
发明人：BHONGLE NANDKUMAR
权利人:HYBRIDON INC
摘要:New methods of synthesizing mono- and oligo- nucleotide H-phosphonates are disclosed. The methods comprise contacting a mononucleoside with phosphonic acid and benzoyl anyhydride to yield the corresponding mononucleoside H-phosphonate. Preferrably a catalytic amount of triphosgene is also used. A similar procedure can be used to couple a first mononucleoside to a second mononucleoside or to an oligonucleotide, the method comprising contacting, in the presence of benzoic anhydride and, preferrably, a catalytic amount of triphosgene, a mononucleotide or oligonucleotide having a free 5' hydroxyl with a mononucleoside having a 3' hydroxyl-bearing phosphorous moiety (preferably H-phosphonate).

摘要:This invention relates to novel multibinding compounds (agents) that are antibacterial agents. The multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands in their monovalent (i.e., unlinked) state have the ability to bind to a an enzyme involved in cell wall biosynthesis and metabolism, a precursor used in the synthesis of the bacterial cell wall and/or the bacterial cell surface thereby interfere with the synthesis and/or metabolism of the cell wall. In particular the multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands hasn a ligand domain capable of binding to penicillin binding proteins, a transpeptidase enzyme, a substrate of a transpeptidase enzyme, a beta-lactamase enzyme, pencillinase enzyme, cephalosporinase enzyme, a transglycoslase enzyme, or a transglycosylase enzyme substrate; Preferably, the ligands are selected from the beta lactam or glycopeptide class of antibacterial agents.
