Antioxidant prenylflavonoids from Artocarpus communis and Artocarpus elasticus

Food Chemistry, 2009
Abstract Two new prenylflavonoids, cyclogeracommunin (1) and artoflavone A (2), were isolated from the cortex of roots of Artocarpus communis. Their structures were determined by spectroscopic methods. Compounds 1, 2 and known compounds, artomunoisoxanthone (3), artocommunol CC (4), artochamin D (5), artochamin B (6), and dihydroartomunoxanthone (7),

Synthesis, biological evaluation of prenylflavonoids as vasorelaxant and neuroprotective agents

Bioorganic & Medicinal Chemistry Letters, 2009
A series of prenylflavonoids with multiple hydroxyl groups were synthesized and evaluated for their vasorelaxant activities against rat aorta rings pre-contracted by phenylephrine (PE), as well as their neuroprotective effects against OGD induced PC12 cell injury.

[New Prenylflavonoid Glycosides from Epimedium koreanum].

Planta medica, 2013
Two new prenylflavonol glycosides epimedokoreanoside I ( 7) and epimedokoreanoside II ( 8) were isolated from EPIMEDIUM KOREANUM Nakai (Berberidaceae) beside five other known prenylflavonol glycosides with hypotensive activity. The structures were elucidated by spectroscopic and chemical methods.

Prenylflavonoids isolated from Artocarpus champeden with TRAIL-resistance overcoming activity

Phytochemistry, 2013
In a screening program for bioactive natural products which can overcome Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-resistance, three prenylflavonoids, named pannokin A-C, were isolated from a MeOH extract of Artocarpus champeden (Moraceae) roots, together with three known prenylflavonoids. The structures of pannokin A-C were

Synthesis of Four Natural Prenylflavonoids and Their Estrogen‐like Activities

Archiv der Pharmazie, 2007
AbstractFour prenylflavonoids, bavachin 1, isobavachin 2, 7,4′‐dihydroxy‐8‐prenylflavone 3, and 8‐prenylapigenin 4 were synthesized and recognized for possessing estrogen‐like activity in MCF‐7/BOS cells, as evaluated by an estrogen‐screening assay. All compounds significantly stimulated the proliferation of MCF‐7/BOS cells in a dose‐dependent manner ...

8-C-Prenylflavonoids from the seed of Tephrosia bracteolata

Phytochemistry, 1981
Abstract Four flavonoids in the seeds of Tephrosia bracteolata were identified as the flavanone obovatin methyl ether and the flavones isopongaflavone, trans-tephrostachin and trans-anhydrotephrostachin.
