Synthesis and anti-Influenza virus activity of 7-O-Alkylated derivatives related to zanamivir
摘要:
A series of 7-alkyl ether derivatives related to zanamivir were synthesized using direct alkylation of the C-7 alcohol of sialic acid. Alkyl ether moiety of less than 12 carbons in length showed low nanomolar inhibitory activity against influenza A virus sialidase. Furthermore, their moiety improved influenza A virus plaque reduction activity compared to zanamivir. However, removal of the 8,9-diol of the 7-O-alkyl derivatives resulted in loss of antiviral potency. This result suggests that 8,9-diol must play an important role in binding with both influenza A and B virus sialidases. (C) 2002 Elsevier Science Ltd. All rights reserved.

[EN] The invention relates to fragrance precursors. In particular, the invention relates to the use of several classes of compounds which can act as fragrance precursors, e.g. in consumer, e.g. cosmetic products, such as deodorants and antiperspirants. These compounds are normally odourless or nearly so, but upon contacting theskin as, for example, in skin care compositions or in personal care compositions, produce fragrances by liberating an odoriferous alcohol. [FR] L'invention concerne des précurseurs de parfums. En particulier, l'invention concerne l'utilisation de plusieurs classes de composés qui peuvent servir de précurseurs de parfums, par exemple, dans des produits de consommation tels que des produits cosmétiques, et plus précisément, des déodorants et des antitranspirants. Ces composés sont normalement sans, ou pratiquement, sans odeur, mais lors de leur contact avec la peau, comme par exemple dans les compositions de soins de beauté ou de soins personnels, ils dégagent un parfum en libérant un alcool odoriférant.
