Phenylpropionamides, Piperidine, and Phenolic Derivatives from the Fruit of Ailanthus altissima.

ABSTRACT: Four novel compounds-two phenylpropionamides, one piperidine, and one phenolic derivatives-were isolated and identified from the fruit of a medicinal plant, Ailanthus altissima (Mill.) Swingle (Simaroubaceae), together with one known phenylpropionamide, 13 known phenols, and 10 flavonoids. The structures of the new compounds were elucidated as 2-hydroxy-N-[(2-O-?-d-glucopyranosyl)phenyl]propionamide (1), 2-hydroxy-N-[(2-O-?-d-glucopyranosyl-(1?6)-?-d-glucopyranosyl)phenyl]propionamide (2), 2?-carboxyl-piperidine-4?-acetic acid methyl ester (4), and 4-hydroxyphenyl-1-O-[6-(hydrogen-3-hydroxy-3-methylpentanedioate)]-?-d-glucopyranoside (5) based on spectroscopic analysis. All the isolated compounds were evaluated for their inhibitory activity against Tobacco mosaic virus (TMV) using the leaf-disc method. Among the compounds isolated, arbutin (6), ?-d-glucopyranosyl-(1?6)-arbutin (7), 4-methoxyphenylacetic acid (10), and corilagin (18) showed moderate inhibition against TMV with IC50 values of 0.49, 0.51, 0.27, and 0.45 mM, respectively.
