  Complementary Flavonoid Prenylations by Fungal Indole Prenyltransferases

  摘要：

  Flavonoids are found mainly in plants and exhibit diverse biological and pharmacological activities, which can often be enhanced by prenylations. In plants, such reactions are catalyzed by membrane-bound prenyltransferases. In this study, the prenylation of nine flavonoids from different classes by a soluble fungal prenyltransferase (AnaPT) involved in the biosynthesis of the prenylated indole alkaloid acetylaszonalenin is demonstrated. The behavior of AnaPT toward flavonoids regarding substrate acceptance and prenylation positions clearly differs from that of the indole prenyltransferase 7-DMATS. The two enzymes are therefore complementary in flavonoid prenylations.

  A further investigation of the methanol-soluble compounds in yellow lupin roots has revealed a new diprenylchromone, a new coumaronochromone (lupinalbin H), a new isoflavone 5,7,4'-trihydroxy-8,3'-di-(3,3-dimethylallyl)isoflavone (isolupalbigenin), and some complex flavanones. The latter compounds have been identified as two known diprenylated flavanones (lonchocarpol A and euchrestaflavanone A), two diasteroisomeric pairs of dihydrofuranoflavanones (lonchocarpols C-1 and C-2, and lonchocarpols D-1 and D-2; the structures formerly proposed for lonchocarpols C and D were also reinvestigated), a new furanoflavanone (lupinenol), and three 8-prenylflavanones with an additional (2RS)-hydroxy-3-methyl-3-butenyl side chain. The structures of the latter flavanones were unambiguously identified by spectroscopic (H-1 NMR) comparison with 6-, 8- and 3'-prenylnaringenins chemically prepared from (2S)-naringenin. The antifungal activity of the prenylated naringenins, and of the various yellow lupin flavanones, was determined by TLC place bioassays using Cladosporium herbarum as the test fungus.
