Imine stilbene analog ameliorate isoproterenol-induced cardiac hypertrophy and hydrogen peroxide-induced apoptosis.

Cardiac hypertrophy is an adaptive response to stress, in order to maintain proper cardiac function. However, sustained stress leads to pathological hypertrophy accompanied by maladaptive responses and ultimately heart failure. At the cellular level, cardiomyocyte hypertrophy is characterized by an increase in myocyte size, reactivation of the fetal gene markers, disassembly of the sarcomere and transcriptional remodelling which are regulated by heart-specific transcription factors like MEF2, GATA4 and immediate early genes like c-jun and c-fos.

Evolvement of nutraceutical onion plants engineered for resveratrol biosynthetic pathway.

Genetically engineered onion expressing codon-optimized VvSTS1 gene accumulated stilbenes and extended life span in yeast and can serve as potential nutraceutical. Resveratrol (RV) is a natural polyphenolic compound found in certain plant species including grapes. RV is well known for its nutraceutical properties and to assuage several disease conditions.

Molecular docking analysis of imine stilbene analogs and evaluation of their anti-aging activity using yeast and mammalian cell models.

The NAD-dependent histone deacetylase SIRT1 was shown to be associated with aging and longevity. A stilbene, resveratrol (RV) was shown to exert anti-aging activity by stimulating the SIRT1 activity. However, the utility of RV is limited by its low bioavailability and structural instability.

Synthesis of Novel Imine Stilbene Analogs Exhibiting Potent Anticancer Activity.

Background: Resveratrol (RV) and its analogues Aza-stilbenes were found effective in exhibiting anticancer activity.

Objective: The present study mainly focused on the green synthesis of novel imine stilbene analogues and evaluation of their anticancer activity besides their influence on hypoxia-induced gene expression in cancer cells.

Method: Novel imine stilbenes, differing in number and/or position of hydroxyl and methoxy functional groups, have been synthesized using green chemistry mediated condensation reaction between aldehydes and amines in the ethanolic extract of Psoralea corylifolia hairy roots and tested for their anticancer potential.
