These heterocycles can also be used as anti-biofilm agents against pathogenic strains, which will minimize the risk of secondary infections.
专利号:US-2004266699-A1 优先权日:2001-10-04 标 题 :Flavonoid compounds capable of modifying the dynamic and/or physical state of biological membranes and to stimulate the endogenous synthesis of stress proteins in eukaryotic cells, relative synthesis and their use 发明人:PORTA AMALIA 摘要:The invention relates to flavonoids compounds of formula (I) and (II) capable of modifying the dynamic and/or physical state of biological membranes and to stimulate the endogenous synthesis of stress proteins in eukaryotic cells. Such compounds are molecules of plant origin or synthetic. The invention also describes a method to identify, purify and chemically synthesize such flavonoid compounds and test their efficacy through their capacity to stimulate the transcription of stress genes and as a consequence, to interact with biological membranes with alteration of their relative physical state. Such compounds and corresponding pharmaceutically acceptable derivatives and/or salts have applications in the areas of pharmaceuticals, more specifically in cosmetics and dermatology, for all those afections related to an alteration of the expression of stress genes.
专利号:WO-9837078-A1 优先权日:1997-02-20 标题 :Solid phase and combinatorial synthesis of substituted thiophenes and of arrays of substituted thiophenes 发明人:DOERWALD FLORENCIO ZARAGOZA 权利人:NOVO NORDISK AS 摘要:A solid phase method for the synthesis of a plurality of differently substituted thiophenes with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The thiophenes are prepared by reaction of a substrate-bound primary or secondary amine with a thiophosgene equivalent and reaction of the resulting intermediate with an acceptor-substituted acetonitrile in the presence of a base. Alkylation with an appropriate alkyl halide, followed by Thorpe-Ziegler-cyclization yields differently substituted, support-bound 3-aminothiophenes. These may be screened on the substrate or cleaved from the substrate and then screened in solution. Alternatively, the resin-bound 3-amino thiophenes or the synthetic intermediates can be subjected to further synthetic transformations (N-acylation, reduction) on the support, which permits the preparation of further therapeutically interesting compounds. The efficient synthesis of a wide variety of thiophenes using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse thiophene-based libraries. The method disclosed here provides an easy and fast access to highly diverse heterocyclic compounds of therapeutic interest, amenable to automatization.
