Synthesis of chalcones bearing 2-hydroperoxy-3-methyl-3-butenyl or 2-hydroxy-3-methyl-3-butenyl group from prenylated chalcones

Chalcones bearing 2-hydroperoxy-3-methyl-3-butenyl or 2-hydroxy-3-methyl-3-butenyl groups, such as xanthoangelol E (1a), xanthoangelol D (2a), psorachalcone A (2 b), xanthohumol D (2c), and related derivatives were first synthesized by using the ene react

Synthesis and antibacterial activity of four natural chalcones and their derivatives

Four natural chalcones bearing hydroxyisoprenyl or prenyl groups, named Paratocarpin E (2), Xanthoangelol D (3), Angusticornin A (4) and Kanzonol C (5), were prepared by employing the Claisen-Schmidt condensation as the key step. In an attempt to investigate the effect of the hydroxyisoprenyl group on biological activity, two of their derivatives were also prepared for antibacterial activity research. The synthesized compounds were investigated for their expected antibacterial activities against Gram positive bacteria (Bacillus subtilis, Staphylococcus aureus) as well as Gram negative bacteria (Escherichia coli, Pseudomonas aeruginosa). Paratocarpin E (2) was found to be the most potent against two Gram positive bacteria while the majority of the remaining compounds showed promising activity as well. However, all of the compounds were inactive against both Gram-negative bacteria.

Preparation method and application of natural product Xanthoangelol D and derivative thereof

The invention discloses a preparation method and application of an isopentenyl chalcone natural product and a derivative thereof. The structural general formula (I) and (II) of the isopentenyl chalcone natural product and the derivative thereof are as follows. Compared with a novel isopentenyl chalcone derivative, the obtained natural product Xanthoangelol D has inhibitory activity improved to a certain degree on bacillus subtilis. The preparation rout of the preparation method has fewer process steps, raw materials are easily available, and the preparation method is suitable for industrial production.

CHALCONES FROM ANGELICA KEISKEI

Four new chalcones, xanthangelols B-E were isolated from roots of Angelica keiskei and their structures determined to be 2',4,4'-trihydroxy-3'-chalcone, 2',4,4'-trihydroxy-3'-chalcon
