Rutin (3,3',4',5,7-pentahydroxyflavone-3-rhamnoglucoside) is a bioactive flavonoid from the plant kingdom. Rutin has been studied as potential anticancer agent due to its wide range of pharmacological properties including antioxidative, anti-inflammatory and anticancer. Autophagy is a conserved intracellular catabolic pathway to maintain cell homeostasis by formation of autophagosome. Processing of autophagy involves various molecules including ULK1 protein kinase complex, Beclin-1-Vps34 lipid kinase complex, ATG5, ATG12, and LC3 (light chain 3). Cargo-carried autophagosomes fuse with lysosomes resulting in autophagolysosome to eliminate vesicles and degrade cargo. However, the actions of rutin on autophagy are not clearly understood. In this study, we analyzed the effect of rutin on autophagy and inflammation in cancer cell lines. Interestingly, rutin induced autophagy in leukemia (THP-1), oral (CA9-22), and lung (A549) cell lines. TNF-${\alpha}$, key modulator of inflammation, was upregulated by inhibition of rutin-induced autophagy. Taken together, these data indicated that rutin induced autophagy and consequently suppressed TNF-${\alpha}$ production.

We investigated the role of vitamin C or rutin on neuropathy and lung damage of diabetic mellitus(DM) rats. Norepinephrine content was significantly decreased in sciatic nerves of DM rats compared with non-DM controls but vitamin C had no effect on decreases of norepinephrine. 2,4-dinitrophenylhydrazine (DNPH) incorporation, which is biomarker of protein oxidation, was increased in sciatic nerve of DM rats as compared with normal control. However, vitamin C had no effects on increases of DNPH incorporation . We measured the content of conjugated dienes (CD) as a biomarker of lipid oxidation in sciatic nerve. CD was increased in DM as compared with normal control, Vitamin C or rutin had no effects on increases of CD. However, Rutin plus vitamin C significantly decreased the content of CD as compared with CIM rats. In lung of DM rats, DNPH incorporation or CD was increased as compared with normal control. Vitamin C or Rutin had no effects on increases of CD However, Rutin plus vitamin C significantly decreased the content of DNPH incorporation or CD in lung tissue. Vitamin C caused marked pathological changes such as the increases of parenchyma and the thickening of alveolar septa in the lung of DM. Rutin had protective effects on the pathological changes in the lung of DM rats. In conclusion, Vitamin C had no effects on oxidative parameter, such as DNPH incorporation or CD, and on the decreases of norepinephrine content in DM rats. Vitamin C caused the marked pathological changes in the lung of DM rats but rutin had protective efforts against the pathological changes.

Purpose: The objective of this study was conducted to investigate the effects of rutin, buckwheat components on cell growth and anti-inflammation in adipocyte 3T3-L1 and human colon cancer cell SW-480. Methods: We cultured 3T3-L1 adipocyte and SW-480 colon cancer cell to confluence, at which time starvation was induced with SFM for 1 day. Cells were then cultured in medium containing 0, 25, 50, or $100{\mu}mol/mL$ of rutin 3T3-L1 or 0, 10, 20, or $40{\mu}mol/mL$ SW-480. Cell viability was measured using a cell viability kit. In addition, we examined the expression of mRNA related to inflammation. RT-PCR was used to quantity tumor necrosis factor ($TNF-{\alpha}$), interleukin-$1{\beta}$ ($IL-1{\beta}$), IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) mRNA levels. Results: Rutin significantly inhibited 3T3-L1 and SW-480 cell proliferation in a dose and time dependent manner. Rutin also significantly reduced the mRNA expression of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ at the highest dose. In addition, rutin treatment caused a significant reduction in COX-2 and iNOS mRNA levels compared to the control group. Conclusion: Overall, our results suggest that rutin has the potential to reduce inflammation, and that these effects are greater during tissue-damaging inflammatory conditions.

A splanchic artery occlusion for 90 min followed by reperfusion of the mesenteric circulation resulted in a severe form of circulatory shock characterized by endothelial dysfunction, severe hypotension, marked intestinal tissue injury, and a high mortality rate. The effect of rutin, a flavonoid having antiprostanoid, anti-inflammatory, antithrombotic, antioxidant effect, were investigated in a model of splanchnic artery occlusion (SAO) shock in urethane anesthetized rats. Occlusion of the superior mesenteric artery for 90 min produced a severe shock state resulted in a fatal outcome within 120 min of reperfusion in many rats. Rutin was given as a bolus (1.28 mg/kg) 10 min prior to reperfusion. Administration of rutin significantly improved mean arterial blood pressure in comparison to vehicle treated rats (p＜0.05). Rutin treatment also resulted in a significant attenuation in the increase in plasma amino nitrogen concentration, intestinal myeloperoxidase activity, intestinal lipid peroxidation, infiltration of neutrophils in intestine and thrombin induced adherence of neutrophils to superior mesentric artery segments. These results suggest that rutin provides beneficial effects in part by preserving endothelial function and attenuating neutrophil accumulation in the ischemic reperfused splanchnic circulation.

The study examined the antioxidant activities and anti-inflammatory effects of rutin from the streptozotocin (STZ)-induced diabetic rats. Results revealed that the levels of plasma glucose and serum glucose were remarkably higher in the STZ-treated group compared to other groups and were significantly reduced in the STZ+rutin treated group compared to the STZ-treated group. In terms of weight, it significantly increased in all experimental groups during the experiment period except for STZ-induced diabetic group. The weight of the STZ-treated group was remarkably reduced compared to other groups. Regarding the weight of each body organ, the STZ-treated group showed higher organ weight compared to the other groups while STZ+rutin-treated group showed significantly reduced kidney and liver weights compared to those of STZ-treated group. In the pancreas tissue of the STZ-treated group, ${\beta}$-cell destruction and vacuolization were observed. Inflammation in the heart, liver, kidney, and retina tissues were also vividly recorded. In the STZ+rutin administered group, the heart and retina tissues were shown to be preserved normally while the liver and kidney tissues showed reduced histopathology in general compared to the STZ-treated group. Conclusionally, the rutin has the effect on the antioxidant activities and anti-inflammation in the STZ-induced diabetic rats.

The protective actions of ambroxol, rutin, glutathione and harmaline on oxidative damages of various tissue components were compared. The mechanisms by which they prevent oxidative tissue damages were explored. Lipid peroxidation of liver microsomes induced by combinations of $Fe^{2+}$ and ascorbate or $Fe^{+3}$, ADP and NADPH was inhibited by $50\; \muM$ of rutin, ambroxol, harmaline and glutathione. Ambroxol ($100\; \muM$) inhibited the degradation of hyaluronic acid by $Fe^{2+}$, $H_2O$_2$ and ascorbate, and it was greater than that of harmaline, whereas hyaluronic acid degradation was not prevented by rutin and glutathione. The compounds used ($100\; \muM$) did not protect the degradation of cartilage collagen by xanthine and xanthine oxidase. Rutin, glutathione and harmaline decreased the degradation of IgG by xanthine and xanthine oxidate, while ambroxol did not attenuate degradation of IgG. Glutathione showed a scavenging action on $H_2O_2$. The compounds all showed scavenging actions on hydroxyl radical. Ambroxol and harmaline exhibited quenching effects en singlet oxygen. In conclusion, ambroxol, rutin, glutathione and harmaline may exert protective effects differently on tissue components against oxidative attack depend on kind of tissue component and free radical.

This experiment was conducted to know the appropriate methods for extraction and determination of rutin contained buckwheat plants. The efficient HPLC analytical condition of rutin contained buckwheat plants was developed. The gradient elution employed a $250mm\times4.6mm$ i.d. Tosoh ODS 120T column. The gradient system was used two mobile phases. A gradient elution was performed with mobile phase A, consisting of $2\%$ Acetic $acid-45\%$ Acetonitrile, and mobile phase B, comprising $2\%$ aqueous acetic acid, and delivered at a flow rate of 1mL/min as follows: 0-18 min, $50-100\%$ A; 18-20 min, $100-50\%$ A; 20-22 min, $50\%$ A. The UV detection wavelength was set at 355 nm. The limit of detection (LOD) for rutin standard compound was 20 ng/mL. And, the higher content of rutin in the extracts was obtained by $80^{\circ}C$ reflex extraction for 120 min. from plants of buckwheat using ethanol.
