Based on the Wnt inhibitors as potential targets in the development of anticancer agents, natural compounds were evaluated for β-catenin-mediated transcriptional activity. A natural lignan hydnocarpin isolated from Lonicera japonica was considered a potential inhibitor for Wnt/β-catenin signalings.
Hydnocarpin (Hy) is a flavonoid isolated and purified from the seeds of Hydnocarpus wightiana Blume. Herein, we have developed a built-in semi-synthetic modification on Hy by one-pot multi-component reaction and a [3 + 2] cycloaddition strategy to append five membered isoxazole and
Five new triterpenoids (1-5), together with two known quassinoids, bruceantin (6) and bruceine A (7), and a known flavonolignan, (-)-hydnocarpin (8), were isolated from the chloroform-soluble subfraction of a methanol extract of the combined twigs, leaves, and inflorescence of Brucea javanica
Flavonolignans are plant natural products, composed of a flavonoid moiety and a lignan (phenylpropanoid) part. Current literature focuses on flavonolignans formed from taxifolin and coniferyl alcohol as e.g. silybin and its congeners from fruit extract from the purple variety of the milk thistle
A phytochemical study of the root and bark of Brucea antidysenterica J. F. Mill. (Simaroubaceae) afforded three new compounds, including a stilbene glycoside bruceanoside A (1), and two canthinone alkaloids bruceacanthinones A (3) and B (4), along with ten known secondary
