    Chemopreventive and therapeutic potential of chrysin in cancer: mechanistic perspectives.[Pubmed: 25596314]
    Chrysin, a naturally occurring flavone, abundantly found in numerous plant extracts including propolis and in honey is one of the most widely used herbal medicine in Asian countries. Nowadays, Chrysin has become the foremost candidate exhibiting health benefits, owing to its multiple bioactivities such as antioxidant, anti-inflammatory, anti-allergic, anti-diabetic, anti-estrogenic, antibacterial and antitumor activities. Anticancer activity is most promising among the multiple pharmacological effects displayed by Chrysin. In vitro and in vivo models have shown that Chrysin inhibits cancer growth through induction of apoptosis, alteration of cell cycle and inhibition of angiogenesis, invasion and metastasis without causing any toxicity and undesirable side effects to normal cells. Chrysin displays these effects through selective modulation of multiple cell signaling pathways which are linked to inflammation, survival, growth, angiogenesis, invasion and metastasis of cancer cells. This broad spectrum of antitumor activity in conjunction with low toxicity underscores the translational value of Chrysin in cancer therapy. The present review highlights the chemopreventive and therapeutic effects, molecular targets and antineoplastic mechanisms that contribute to the observed anticancer activity of Chrysin.

    Chrysin alleviates testicular dysfunction in adjuvant arthritic rats via suppression of inflammation and apoptosis: comparison with celecoxib.[Pubmed: 24932515]
    Chrysin, a natural flavone and celecoxib, a selective COX-2 inhibitor, in testicular impairment in rats with adjuvant arthritis, an experimental model of RA. Chrysin (25 and 50mg/kg) and celecoxib (5mg/kg) were orally administered to Wistar rats once daily for 21days starting 1h before arthritis induction. Chrysin suppressed paw edema with comparable efficacy to celecoxib. More important, Chrysin, dose-dependently and celecoxib attenuated the testicular injury via reversing lowered gonadosomatic index and histopathologic alterations with preservation of spermatogenesis. these findings highlight the protective effects of Chrysin and celecoxib against testicular dysfunction in experimental RA which were mediated via boosting testosterone in addition to attenuation of testicular inflammation, oxidative stress and apoptosis. Generally, the 50mg/kg dose of Chrysin exerted comparable protective actions to celecoxib.

    Suppression of inflammatory response by chrysin, a flavone isolated from Potentilla evestita Th. Wolf. In silico predictive study on its mechanistic effect.[Pubmed: 25819005]
    Flavonoids are the most abundant natural polyphenols widely distributed in plants. Among them, Chrysin has recently attracted the attention for its anti-tumor and anti-oxidant activities and also for its protective effects on allergic inflammation. Therefore, in this study, we set out to investigate and characterize the effects of Chrysin in classical models of inflammation reasoning that this would expand our knowledge on the pharmacological properties of this flavone. To this aim we have firstly isolated Chrysin from Potentilla evestita Th. Wolf. and successively evaluated its anti-inflammatory and analgesic potential on writhing and formalin test and also on carrageenan-induced paw oedema. Finally, the present study was planned to investigate, by the aim of docking analysis, the molecular interaction of this compound on the binding site of COX-1 and COX-2 enzymes. On writhing test, we observed a significant inhibition of writhings after the administration of Chrysin at 5.0 and 10.0mg/kgi.p. (25.00±9.22% and 55.67±7.62% respectively). On formalin test, the flavone at dose of 10.0mg/kgi.p. displayed its maximum analgesic and anti-inflammatory effect on both early (35.67±7.88%) and late phase (50.57±5.36%) and similarly displayed at 4h a significant anti-inflammatory effect in carrageenan-induced paw oedema. Moreover, in silico analysis of receptor ligand complex shows that Chrysin interacts weakly with COX-1 binding site whereas displayed a remarkable interaction with COX-2. These findings suggest that the flavone Chrysin isolated from P. evestita Th. Wolf. possesses in vivo anti-inflammatory and anti-nociceptive potential, which are supported in silico by an interaction with COX-2 binding site.

    Chrysin, an anti-inflammatory molecule, abrogates renal dysfunction in type 2 diabetic rats.[Pubmed: 24848621]
    We investigated the nephroprotective effects of Chrysin (5, 7-dihydroxyflavone) in a high fat diet/streptozotocin (HFD/STZ)-induced type 2 diabetic Wistar albino rat model. Chrysin is a potent anti-inflammatory compound that is abundantly found in plant extracts, honey and bee propolis. The treatment with Chrysin for 16weeks post induction of diabetes significantly abrogated renal dysfunction and oxidative stress. Chrysin treatment considerably reduced renal TNF-α expression and inhibited the nuclear transcription factor-kappa B (NF-кB) activation. Furthermore, Chrysin treatment improved renal pathology and suppressed transforming growth factor-beta (TGF-β), fibronectin and collagen-IV protein expressions in renal tissues. Chrysin also significantly reduced the serum levels of pro-inflammatory cytokines, interleukin-1beta (IL-1β) and IL-6. Moreover, there were no appreciable differences in fasting blood glucose and serum insulin levels between the Chrysin treated groups compared to the HFD/STZ-treated group. Hence, our results suggest that Chrysin prevents the development of DN in HFD/STZ-induced type 2 diabetic rats through anti-inflammatory effects in the kidney by specifically targeting the TNF-α pathway.

    Chrysin inhibits cell invasion by inhibition of Recepteur d'origine Nantais via suppressing early growth response-1 and NF-κB transcription factor activities in gastric cancer cells.[Pubmed: 25625479]
    Chrysin is a naturally occurring phytochemical, a type of flavonoid, which has been reported to suppress tumor metastasis. However, the effects of Chrysin on RON expression in gastric cancer are not well studied. In the present study, we examined whether Chrysin affects RON expression in gastric cancer, and if so, its underlying mechanism. We examined the effect of Chrysin on RON expression and activity, via RT-PCR, promoter study, and western blotting in human gastric cancer AGS cells. Chrysin significantly inhibited endogenous and inducible RON expression in a dose-dependent manner. After demonstrating that Egr-1 and NF-κB are the critically required transcription factors for RON expression, we discovered that Chrysin suppressed Egr-1 and NF-κB transcription factor activities. Additionally, the phorbol-12-myristate-13-acetate- (PMA) induced cell invasion was partially abrogated by Chrysin and an RON antibody. Our results suggest that Chrysin has anticancer effects at least by suppressing RON expression through blocking Egr-1 and NF-κB in gastric cancer AGS cells.
