Synthesis of UDP-GlcNAc derivatives modified at OH-4 as potential chain-terminators of chitin biosynthesis
摘要:
A series of UDP-GlcNAc derivatives and precursors that have been modified at the 4-position were synthesised from N-acetyl glucosamine as potential chain terminators of chitin biosynthesis. None of the UDP-derivatives or the precursors tested displayed any significant anti-fungal activity in cell adhesion or germination assays on the dermatophyte Trichophyton rubrurn.

[EN] This invention provides a method for inhibiting oligosaccharide biosynthesis in vivo and in vitro comprising the steps of administering at least one monosaccharide derivative, wherein the hydroxyl group which is the glycosyl acceptor (i.e. the active hydroxyl group) of said at least one monosaccharide is substituted by a suitable group or an isostere. This invention further provides a method of treatment of diseases or illnesses associated with oligosaccharide biosynthesis in the human or animal body. Additionally, the present invention provides pharmaceutical compositions comprising monosaccharide derivatives. Furthermore, this invention provides novel monosaccharide derivatives and processes for synthesising the monosaccharide derivatives. [FR] La présente invention concerne une méthode d'inhibition in vivo et in vitro de la biosynthèse des oligosaccharides, ladite méthode comprenant les étapes d'administration d'au moins un dérivé de monosaccharide, le groupement hydroxy qui joue le rôle d'accepteur de glycosyle (c'est-à-dire le groupement hydroxy actif) du ou des monosaccharides étant substitué par un groupement ou un isostère adapté. La présente invention concerne également une méthode de traitement de maladies ou d'affections associées à la biosynthèse des oligosaccharides dans les organismes humains ou animaux. En outre, la présente invention concerne des compositions pharmaceutiques comprenant des dérivés de monosaccharide. De plus, la présente invention concerne de nouveaux dérivés de monosaccharide et des procédés de synthèse desdits dérivés de monosaccharide.
