New homoisoflavonoid analogues protect cells by regulating autophagy

As a special group of naturally occurring flavonoids, homoisoflavonoids have been discovered as active components of several traditional Chinese medicines for nourishing heart and mind. In this study, twenty homoisoflavonoid analogues, including different substitution groups on rings A and B, as well as heteroaromatic B ring, were synthesized and evaluated for their cardioprotective and neuroprotective activities. In a H2O2-induced H9c2 cardiomyocytes injury assay, nine homoisoflavonoid analogues showed promising activities in the same level as the positive control, diazoxide. Six cardioprotective compounds with representative structure diversities were then evaluated for their neuroprotective effects on MPP+ induced SH-SY5Y cell injury model. Furthermore, autophagy inducing monodansylcadaverine (MDC) fluorescence staining methods and molecular docking studies indicated the action mechanism of these compounds may involve autophagy regulating via class I PI3K signaling pathway.

New convenient synthesis of homoisoflavanones and (±)-di-O- methyldihydroeucomin

Upon reaction of 1-(2-hydroxyphenyl)-3-phenylpropane-1-ones (2′-hydroxydihydrochalcones) with dimethylaminodimethoxymethane in boiling toluene, the corresponding 3-benzylchromones are obtained in excellent yields. These latter lead to 3-benzylchroman-4-on

Synthesis and angioprotective, antiallergic and antihistaminic activities of 3-benzyl-chromones (homoisoflavones)

Various 3-benzyl-chromones were prepared and their angioprotective antiallergic and antihistaminic activities were studied. - 3-benzyl-chromones / antiallergic / antihistaminic / angioprotective
