RESUMO

Chalcones (trans-1,3-diphenyl-2-propen-1-ones) form simple chemical structures that act as precursors for the biogenesis of flavonoids. These are distributed in plants and have two aromatic or heteroaromatic rings connected by a three-carbon α, ß-unsaturated carbonyl group. Considering the importance of chalcones as monoamine oxidase and acetylcholinesterase inhibitors, the study was designed as a comprehensive and systematic analysis to evaluate the pharmacological activities leading to the formation of drug molecules against Alzheimer's disease (AD). Based on our previous research, 11 indolyl chalcones (IC1-IC11) were synthesised and investigated for MAO-B inhibitory activity. The inhibitory potential was evaluated based on binding and reversibility studies using purified enzymes. The active and most promising molecule, (2E)-3-(4-bromophenyl)-1-(1H-indol-3-yl) prop-2-en-1-one (IC9), also found predominant acetylcholinesterase inhibition and hence it was found dual acting in vitro. Based on this, the molecule IC9 was further subjected to cell line studies to further explore its role as a neuroprotective agent against neuronal degeneration, one of the main contributing parameters related to AD.

RESUMO

The prevalence of liver disease is increasing year by year and it is recognized as a main health burden across the world. Nowadays, dietary nutraceuticals are found to be very effective in the prevention and treatment of liver diseases. The virgin coconut oil and phosphatidylcholine are found to have a wide range of therapeutic efficacy and the most important among them is its hepatoprotective activity. In the present study, we had evaluated the hepatoprotective effect of the novel formulation with the combination of these two which is named as Phoscoliv. For the study, adult Wistar rats were grouped into Normal control, Paracetamol-treated, and Paracetamol along with Phoscoliv-treated group. In order to evaluate the hepatoprotective effect of the drug, various parameters were analyzed. Data obtained from the study showed that Phoscoliv supplementation were found to significantly boost up the antioxidant status by enhancing the SOD, CAT, GPx, and GSH level and thereby inhibit the generation of ROS and also blocked lipid peroxidation, which was confirmed by the reduced level of TBARS. The release of pro-inflammatory cytokines was also decreased, which was eventually helped to maintain the normal architecture of the liver. Thus, from the overall result of this study reveals that Phoscoliv can be effectively used as a potent and safe hepatoprotective medicine. PRACTICAL APPLICATIONS: The over or unwanted usage of synthetic medicine is a serious problem because it can cause so many adverse health effects. Liver-related disorders are the major side effects of these drugs. Food habits of ancient people dictate that there is no other better medicine than a good food. So, treating a disease with a food or compounds derived from a food item will be more effective. Virgin coconut oil is a type of natural and organic oil, which has the capability of maintaining the body in a healthy state. Likewise, phosphatidylcholines are very important phospholipid nutrients necessary to keep the cells healthy. Both these have the potential to protect and prevent the liver damages. Therefore, the combination of these two can exhibit profound hepatoprotective activity.

RESUMO

A 6-week, randomized, open-label, active-controlled clinical trial was conducted to evaluate the influence of a low-dose curcumagalactomannosides (CGM) (400 mg once daily) in OA subjects. The treatment was compared with a standard combination of 500 mg glucosamine hydrochloride (GLN) and 415 mg chondroitin sulphate (CHN), supplied as a single oral dose twice a day. Out of 84 subjects randomized, 72 subjects who have completed the study were evaluated for the safety and efficacy of the treatments at baseline and subsequent visits (day 28 and 42), by measuring walking performance, VAS, KPS, and WOMAC scores. CGM exhibited 47.02, 21.43, and 206% improvement in VAS, KPS, and walking performance, respectively, compared to the baseline. Similarly, there was 31.17, 32.93, 36.44, and 35% improvement in the pain, stiffness, physical function, and total WOMAC scores. CGM also caused a substantial reduction in the serum inflammatory marker levels. The results indicate that a short-term supplementation of a low dosage CGM exerted superior beneficial effects than a high-dosage CHN-GLN combination in alleviating the pain and symptoms of OA subjects. Further clinical trials of extended duration in a larger population is required to substantiate the efficacy of CGM in the long-term management of OA.

RESUMO

Objective: A combination of curcumagalactomannosides (CGM) (400 mg) with glucosamine hydrochloride (GLN) (500 mg) was evaluated against a standard dietary supplement combination chondroitin sulfate (CHN) (415 mg)/GLN (500 mg) for their effectiveness in alleviating the pain and symptoms among osteoarthritic subjects. Design: Randomized, double-blinded and active-controlled study. Settings/Location: The study was conducted in a hospital-based research center in Vadodara, Gujarat, India. Subjects: Eighty subjects (38 males and 42 females), with confirmed osteoarthritis (OA) (Class I-III), were randomized into two parallel groups designated as Group I (CGM-GLN) and Group II (CHN-GLN). Interventions: All the study subjects were supplemented with their corresponding intervention capsules (ether CGM along with GLN or CHN along with GLN), as a single oral dose twice a day, once in the morning 10-15 min before breakfast and again in the evening before dinner, for 84 days. Outcome measures: A validated treadmill uphill walking protocol was used for the study, and the efficiency of supplementation was evaluated using visual analogue scale (VAS) score, Karnofsky Performance Scale (KPS) score, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire at the baseline, 28th, and 84th day following the treatment. Mechanism of action of CGM-GLN combination was analyzed by measuring the levels of serum inflammatory markers interleukin 1 beta (IL-1ß), interleukin 6 (IL-6), and soluble vascular cell adhesion molecule-1 (sVCAM) at the baseline and 84th day. Results: CGM-GLN was found to offer significant beneficial effects to pain, stiffness, and physical function of OA subjects compared with CHN-GLN, which was evident from the improvement in walking performance, VAS score, KPS score, and WOMAC score. The efficiency of CGM-GLN was almost double compared with the CHN-GLN by the end of the study (84th day). A significant reduction of inflammatory serum marker levels was observed among CGM-GLN subjects compared with CHN-GLN subjects. Compared with the baseline, CGM-GLN produced 54.52%, 59.08%, and 22.03% reduction in IL-1ß, IL-6, and sVCAM levels, respectively. Whereas CHN-GLN group of subjects expressed only 23.17%, 21.38%, and 6.82% reduction in IL-1ß, IL-6, and sVCAM levels, respectively. Conclusions: In conclusion, the present study demonstrated the potential benefits of CGM-GLN supplements in alleviating the symptoms and function of OA subjects compared with the standard CHN-GLN treatment. The augmented efficacy of CGM-GLN combination could be attributed to the enhanced anti-inflammatory effect of CGM.

RESUMO

Diabetes Mellitus is a common metabolic or endocrine disorder that occurs as a result of insufficient amounts of insulin secretion or defect in the action of insulin produced from pancreatic beta cells. Antioxidant containing food items are very effective in reducing complications that arise due to diabetes, indicating that it may be beneficial for treating metabolic disorders. In this study, we used some essential nutrients enriched with glutathione, named as Glothione (GN), and evaluated the antidiabetic effect of GN in alloxan-induced diabetic rats. The treatment with GN showed significant reduction in the blood glucose level, HbA1c level, and liver markers like SGOT, SGPT, and ALP and shows increased antioxidant status and decreased inflammatory markers. Histopathological analysis of pancreas and liver tissue showed that there were no abnormalities in the rat after the administration of GN. Thus, antioxidant-enriched formulation of GN can be used as a potent hypoglycaemic drug. PRACTICAL APPLICATIONS: Glothione is a glutathione-enriched formulation that contains essential nutrients required for the normal functioning of the body. Recent trends in lifestyle and food habits have been noted to cause health risks and subject the body through physical and physiological stress--hence the importance of antioxidant-rich foods. Antioxidants are capable of boosting metabolism and other physiological processes. Thus, the consumption of GN can enhance the antioxidant status within the body. GN does not contain any chemical ingredients so it will not cause any side effects. It has a strong antidiabetic effect and is also able to control a number of diseases.

RESUMO

Purpose: Chalcones are precursors of flavonoids with a wide range of pharmacological activities. This study evaluates the anti-inflammatory effect of indole based chalcone derivative (2E)-3-(4-bromophenyl)-1-(1H-indol-3-yl) prop-2-en-1-one (IC9) on lipopolysaccharide (LPS) activated murine macrophages RAW264.7 cells and carrageenan-induced acute model in rats.Materials and methods: LPS-treated RAW264.7 cell lines and carrageenan-induced animal model were employed to evaluate the anti-inflammatory activity of IC9. The cell cytotoxicity studies were carried out by MTT assay. Reactive oxygen species (ROS) production and other inflammatory markers such as prostaglandin E2 (PGE2), nitric oxide (NO) as well as cyclooxygenase-2 (COX-2) activity were determined using ELISA. The RT-PCR was performed to determine mRNA expressions in the case of inducible nitric oxide synthase (iNOS), COX-2, Toll-like receptor-4 (TLR-4) and also nuclear translocation of NF-κB activity.Results: LPS-activated RAW264.7 cells showed an increased level of ROS generation and other inflammatory markers such as PGE2, NO level and COX-2 activity. Expression of iNOS, COX- 2 and TLR-4 mRNA expression were also up-regulated along with nuclear translocation of NF-κB. On IC9 supplementation, all the above parameters of LPS-activated cells were found to be reversed, resembling the control group. Moreover, IC9 significantly inhibited paw swelling and exhibited maximum inhibition of 78.45% at low dose of 7.5 mg/kg.bwt.Conclusions: The targeting anti-inflammatory efficacy and profound NF-κB sensitive transcriptional regulatory mechanism of IC9 accounts for its effective anti-inflammatory action.

RESUMO

Acetaldehyde, the major cytotoxin formed by the metabolism of alcohol, is responsible for liver injury, extracellular matrix alterations, inflammation, and hangover in heavy drinkers. This study aimed to demonstrate the efficacy of a standardized polyphenolic extract of clove buds (Clovinol) in ameliorating the oxidative stress and inflammation caused by the accumulation of acetaldehyde after binge drinking. We used a randomized, double-blinded crossover study with 16 male social drinkers. The subjects were randomized into two groups of eight subjects and received either placebo or Clovinol in a single hard shell gelatin capsule (250 mg × 1) per day. The dosage of alcohol was 1 g/kg body weight/day. After 2 weeks of washout period, the treatment regime was reversed. Blood samples were drawn at 0, 0.5, 2, 4, and 12 h after treatment with either placebo or Clovinol, and biochemical parameters were analyzed. Hangover severity score was determined by using a validated questionnaire as reported earlier. Results showed faster elimination of blood acetaldehyde with significant decreases in oxidative stress, lipid peroxidation, C-reactive protein, interleukin-6, and significant enhancement in glutathione and superoxide dismutase as compared with placebo along with an overall reduction of 55.34% in hangover severity in Clovinol-treated subjects. This study demonstrated the efficacy of clove bud polyphenols for alleviating alcohol-related side effects among social drinkers at the studied dose.
