Abstract

Three new prenylated isoflavones, 5,7-dihydroxy-6-(2″-hydroxy- 3″-methylbut-3″-enyl)-4′-methoxylisoflavone (1), 5,4′-dihydroxy-6-(3″-methylbut-2′-enyl)-2‴-(4‴- hydroxy-4‴-methylethyl)-3‴-methoxydihydrofurano-[4‴, 5‴;7,8]isoflavone (2), and 5,4′-dihydroxy-8-(3″-methylbut- 2″-enyl)-2‴-(4‴-hydroxy-4‴-methylethyl) furano-[4‴,5‴;6,7]isoflavone (3), a benzylated dihydroflavonol, 5,7,4′-trihydroxy-8-p-hydroxybenzyldihydroflavonol (4), and eight known flavonoids (5-12) were isolated from the fruits of Cudrania tricuspidata. The structures of these compounds were determined on the basis of MS and ¹H and ¹³C NMR spectroscopic data, including 2D NMR experiments. Compounds 2, 3, 6, 7, 8, 10, 11, and 12 inhibited LPS-induced nitric oxide production, with IC₅₀ values of 11.8-41.8 μM.
