• Synthesis and in vitro study of novel 7-O-acyl derivatives of Oroxylin A as antibacterial agents

  日期：2005.9

  A series of Oroxylin A derivatives, prepared by alkylation and condensation, were fully characterized by spectroscopic methods. All the derivatives were screened for antibacterial activity against a panel of susceptible and resistant Gram-positive and Gram-negative organisms. It was observed that acylation of 7-OH group in Oroxylin A significantly enhanced the activity as compared to their parent compound (Oroxylin A).

  The present invention relates to identification of Oroxylum indicum, Indian medicinal plant as a rich source for flavanoid compounds. Mucoprotective and antigastric ulcer properties in the flavone class of compounds isolated therefrom have been identified along with a flavanoids mixture in substantial yields from hexane and acetone extracts. The hexane extract was fractionated, purified and the compounds identified as Oroxylin A, Chrysin and Baicalein. The acetone extract was purified and the compounds obtained identified as methoxy chrysin, Oroxyloside methyl ester and chrysin-7-O-methyl glycoside.

Les propriétés mucoprotectrices et anti-ulcère gastrique des composés de la classe des flavones isolés à partir de cette plante ont été identifiées, et un mélange de flavonoïdes a été obtenu avec des rendements substantiels à partir d'extraits hexaniques et acétoniques. L'extrait hexanique a été fractionné, purifié et les composés identifiés comme étant l'oroxyline A, la chrysine et la baïcaléine. L'extrait acétonique a été purifié et les composés obtenus ont été identifiés comme étant la méthoxychrysine, l'ester méthylique d'oroxyloside et le 7-O-méthylglycoside de chrysine.
