  Synthesis and Structures of Regioisomeric Hydnocarpin-Type Flavonolignans

  摘要：

  Flavonolignans represent natural compounds whose biosynthesis presumes a radical coupling of a ring B catecholic flavonoid with a molecule of coniferyl alcohol or an analogue. Many natural flavonolignans can exist as regioisomers, depending on how the coupled coniferyl alcohol moiety orients to the flavonoid. These regioisomers are often difficult to separate and have virtually identical NMR spectra. Structural assignments for some have changed with time or have been given without proof. We here report syntheses of both regioisomers of the flavonolignan hydnocarpin and one isomer of a plant isolate previously known as 5'-methoxyhydnocarpin. This isomer, here renamed 5'-methoxyhydnocarpin-D, was recently shown to be a potent inhibitor of a Staphylococcus aureus multidrug resistant efflux pump.

  The present invention provides a method for determining the presence of a multidrug resistance (MDR) pump inhibitor in a natural antibiotic producing source, including plants and microorganisms, such as fungi and bacteria. The plant is selected from plants which produce amphiphilic cations such as isoquinolines, e.g., berberine and protoberberinium alkaloids. The present invention also provides flavolignans and porphyrin derivative compounds which have been identified by the method of the present invention as being MDR pump inhibitors.
