Metabolomic Profiling

In this research work, the antioxidant and metabolomic profiling of seven selected medicinally important herbs including Rauvolfia serpentina, Terminalia arjuna, Coriandrum sativum, Elettaria cardamom, Piper nigrum, Allium sativum, and Crataegus oxyacantha was performed. The in vivo cardioprotective potential of these medicinal plants was evaluated against surgically induced oxidative stress through left anterior descending coronary artery ligation (LADCA) in dogs. The antioxidant profiling of these plants was done through DPPH and DNA protection assay. The C. oxyacantha and T. arjuna showed maximum antioxidant potential, while the E. cardamom showed poor antioxidative strength even at its high concentration. Different concentrations of extracts of the said plants exhibited the protection of plasmid DNA against H2O2 damage as compared to the plasmid DNA merely treated with H2O2. The metabolomic profiling through LC-MS analysis of these antioxidants revealed the presence of active secondary metabolites responsible for their antioxidant potential. During in vivo analysis, blood samples of all treatment groups were drawn at different time intervals to analyze the cardiac and hemodynamic parameters. The results depicted that the group pretreated with HC4 significantly sustained the level of CK-MB, SGOT, and LDH as well as hemodynamic parameters near to normal. The histopathological examination also confirmed the cardioprotective potential of HC4. Thus, the HC4 being safe and inexpensive cardioprotective herbal combination could be considered as an alternate of synthetic drugs.

Context: The medicinal plants have enormous pharmacological properties and having fewer side effects. Today there is increasing demand of medicinal plants as an anti-aging and anti-wrinkle agent. Objective: The aim of this study is to evaluate antioxidant, anti-aging and anti-wrinkle potential of Salvia officinalis. Materials and Methods: Salvia officinalis (Lamiaceae) is folk medicine of Asia and Latin America. Powdered crude drug 100 g were successively extracted in a soxhlet apparatus with petroleum ether (60-80ºC), chloroform and methanol. After successive solvents extraction methanolic extract was used for testing of antioxidant potential using DPPH assay. Further, antiaging potential of extract was investigated by inhibitory effect of various enzymatic estimations i.e. Col-I, Ela-I and Hya-I inhibitory assays on early aging human skin fibroblasts. Antiwrinkle potential of plant Salvia officinalis was done by using UV light induced photo aging model. Results: Phytochemical analysis showed the presence of glycosides, alkaloids flavonoids, and triterpenoids, saponins and Phenolic compounds in high level. Extract showed inhibitory concentration (IC50:24.65) and ascorbic acid the standard antioxidant showed inhibitory concentration (IC50:20.10). In enzymatic estimations assay, the Col-I, Ela-I and Hya-I of extract were assessed showing inhibitory concentration as Col-I (IC50:21.36), Ela-I (IC50:35.05) and Hya-I (IC50:23.44) respectively. Thus, MeOH extract of Salvia officinalis able to inhibit 50% of the activity of aging related enzymes Col-I, Ela-I and Hya-I. The wrinkle score of negative control i.e. UV treated group was 2.83±0.408 and MeOH extract of Salvia officinalis treated group is 1.83 ±0.753. Conclusion: This study concluded that MeOH extract of Salvia officinalis has confirmed the high antioxidant potential and In vitro and In vivo inhibitory potential of antiaging enzymes assessed, thus they could be used for further development of cosmetic products and nutraceuticals.

Whether aucubin could protect myocardial infarction- (MI-) induced cardiac remodeling is not clear. In this study, in a mouse model, cardiac remodeling was induced by left anterior descending coronary artery ligation surgery. Mice were intraperitoneally injected with aucubin (10 mg/kg) 3 days post-MI. Two weeks post-MI, mice in the aucubin treatment group showed decreased mortality, decreased infarct size, and improved cardiac function. Aucubin also decreased cardiac remodeling post-MI. Consistently, aucubin protected cardiomyocytes against hypoxic injury in vitro. Mechanistically, we found that aucubin inhibited the ASK1/JNK signaling. These effects were abolished by the JNK activator. Moreover, we found that the oxidative stress was attenuated in both in vivo aucubin-treated mice heart and in vitro-treated cardiomyocytes, which caused decreased thioredoxin (Trx) consumption, leading to ASK1 forming the inactive complex with Trx. Aucubin increased nNOS-derived NO production in vivo and vitro. The protective effects of aucubin were reversed by the NOS inhibitors L-NAME and L-VINO in vitro. Furthermore, nNOS knockout mice also reversed the protective effects of aucubin on cardiac remodeling. Taken together, aucubin protects against cardiac remodeling post-MI through activation of the nNOS/NO pathway, which subsequently attenuates the ROS production, increases Trx preservation, and leads to inhibition of the ASK1/JNK pathway.

Humans are increasingly exposed to heavy-metals from food, water, medicine, vaccines, and cosmetics. The toxicity of heavy-metals in humans is briefly summarized, links the possible causal relationships between a high heavy-metals body burden and a number of neurological disorders including Alzheimer’s, Parkinson and Autism disorders. This study aimed to assess the antioxidant properties of Astaxanthin (ASTA) to determine the effect of orally administered ASTA capability of restrict accumulation and toxicity of heavy-metals in brain of rats. It also, assess against Hydrogen peroxide induced oxidative stress and antioxidant potential properties of ASTA with comparing the affectivity of 5% and 10% of ASTA in increased glutathione-recycling enzymes (GPx oxidation). A significant change was observed as increased glutathione-recycling enzymes (GPx oxidation) of rats and showed a protective effect against accumulation of Aluminum(AL) in rat’s brain tissues. The results of this in-vivo study demonstrated that ASTA 10% is more can affective in restriction of accumulation and toxicity of Al in rate brain and its contented can protects against oxidative-stress.

Antioxidant Supplements

Due to high oxygen consumption, the brain is particularly vulnerable to oxidative stress, which is considered an important element in the etiopathogenesis of several mental disorders, including schizophrenia, depression and dependencies. Despite the fact that it is not established yet whether oxidative stress is a cause or a consequence of clinic manifestations, the intake of antioxidant supplements in combination with the psychotropic therapy constitutes a valuable solution in patients’ treatment. Anyway, some drugs possess antioxidant capacity themselves and this aspect is discussed in this review, focusing on antipsychotics and antidepressants. In the context of a collection of clinical observations, in vitro and in vivo results are critically reported, often highlighting controversial aspects. Finally, a new challenge is discussed, i.e., the possibility of assessing in silico the antioxidant potential of these drugs, exploiting computational chemistry methodologies and machine learning. Despite the physiological environment being incredibly complex and the detection of meaningful oxidative stress biomarkers being all but an easy task, a rigorous and systematic analysis of the structural and reactivity properties of antioxidant drugs seems to be a promising route to better interpret therapeutic outcomes and provide elements for the rational design of novel drugs.
