1Endotoxic shock can be elicited by a systemic injection of LPS which induces the production and release of several cytokines.2 In response to these cytokines, several reactive oxygen species (ROS) are produced from cells such as neutrophils and other phagocytic cells, creating a status of oxidative stress.3 Thus, this type of stress may hypothetically support the assumption that LPSinduced cell injury would be retarded by modifying free radical metabolism with the aid of potent antioxidant pre-treatment from nature. Certain reports have claimed that a few herbal extracts can act on the central nervous system, thereby enhancing the faculties of learning and memory. 4 The . At the end of the study, rats were sacrificed, brain hippocampal region was removed and biochemical parameters were measured. Results: In WMT swimming length (cm) was increased in LPS-treated rats when compared to control animals, the swimming length (EEPM; 400 mg/kg) was found to be significant; in RAM, different doses of EEPM at 100, 200 and 400 mg/kg decreased the number of errors in entry 4.00±0.36, 4.16±0.16and 3.33±2.79 respectively when compared with control animals (2.66± 0.21). EEPM at 400 mg/kg showed significant activity, in CRT apparatus increased incorrect lever pressing was observed in LPS-treated rats when compared to control animals. Incorrect lever pressing was minimized by EEPM at 400 mg/kg (43.5±2.40). Conclusions: Our results showed that EEPM is a hopeful aspirant for hindrance of infection and inflammation induced brain damage by LPS.
Background: Breast cancer is one of the malignant tumours which mainly affect the female population. Total 20% of the cases of breast cancer are due to overexpression of Human epidermal growth factor receptor-2 (HER2), which is the dominant tyrosine kinase receptor. In general, 9-anilinoacridine derivatives play an important role as antitumor agents due to their DNA-intercalating properties. Objective: Some novel 9-anilinoacridines substituted with pyrazole moiety(1a-z) were designed, and their HER2enzyme (PDB id-3PP0) inhibition activity was evaluated by molecular docking studies using the Glide module of Schrodinger suite 2019-4. Methods: Glide module of the Schrodinger suite was used to perform docking studies, qikprop module was used for in-silico ADMET screening, and the Prime-MM-GBSA module was used for free binding energy calculations. Using GLIDE scoring functions, we can determine the binding affinity of ligands (1a-z) towards HER2. Results: The inhibitory activity of ligands against HER2 was mainly due to the strong hydrophobic and hydrogen bonding interactions. Almost all the compounds 1a-z have a good binding affinity with Glide scores in the range of -4.9 to -9.75 compared to the standard drugs CK0403(-4.105) and Tamoxifen (-3.78). From the results of in-silico ADMET properties, most of the compounds fall within the recommended values. MM-GBSA binding calculations of the most potent inhibitors are more favourable. Conclusion: The results of in-silico studies provide strong evidence for the consideration of valuable ligands in pyrazole substituted 9-anilinoacridines as potential HER2 inhibitors, and the compounds, 1v,s,r,d, a,o with significant Glide scores may produce significant anti-breast cancer activity for further development.
Many diseases have become easier to diagnose and treat as a result of advancements in medical science and technology, but strokes, which have multiple etiologies and mechanisms, continue to be difficult to treat. Synthetic drugs are notorious for causing a slew of unavoidable side effects. Herbal drugs have a wide range of mechanisms of action and are typically free of side effects, making them excellent alternatives to synthetic drugs for stroke treatment. Cyclea peltata (Lam) Hook f. Thoms roots were studied for their neuroprotective properties against fluoride-induced neurodegeneration in rats. The rat brain homogenate was investigated for the levels of non-enzymatic antioxidants like norepinephrine and serotonin to analyse the health of the brain. Both the hormones norepinephrine and serotonin levels were restored due to the treatment with ethanol extract of the plant. The antioxidant enzyme levels like SOD, CAT, GSH and GPx in the rat brain were estimated, and the results were similar to the non-enzymatic levels. The elevation of antioxidant enzymes indicates that the extract had an antioxidant mechanism that is responsible to help in the prevention of neurodegeneration of rats. In the brain tissues treated with Cyclea peltata extract, there was a significant increase in antioxidant enzymes and a reduction in lipid peroxidation, confirming the antioxidant mechanisms responsible for stroke prevention in extract-treated groups. The root extract of Cyclea peltata was found to show a reasonable inhibitory effect on neurodegeneration when delivered at a dose of 200mg/kg.
Herbal plants have been used to avert and to heal numerous ailments for thousands of years. There are reputable sources of active components using their health beneficial effects, and repeatedly, these sources are materials for gourmet food feastings. Specific bioactive components from the herbs have been established for their anti-neoplastic activities. The herbal plant Pedalium murex Linn (Family: Pedaliaceae) universally known to the world as “Large Caltrops”. The plant is rich in flavonoids, phenolics and glycosides. The key target of the contemporary research was to explore the free radical scavenging, in vitro anti-tumour potential of Pedalium murex Linn leaves in non-polar petroleum ether & polar ethanol solvent extracts. Preliminary phytochemical examination of extracts showed that this plant leaf contains alkaloids, flavonoids, glycosides, saponins, steroids & tannins. This initial investigation proved that Pedalium murex Linn (95% v/v of ethanol extract) leaves (EEPM) were significantly reduced and inhibit the free radicals. IC 50 values were representing, EEPM possessed strong anti-oxidant activity when compared to petroleum ether extract of Pedalium murex Linn. leaves. In vitro anti-neoplastic activity of EEPM was studied on the two different cancer cell lines such as HCT116, HepG2 by MTT assay method. All the four different doses of EEPM (62.5, 125, 250 & 500 µg/ml) produced significant activity against HepG2 cell lines. It shows that phyto lead molecules such as flavonoids & phenolic compounds existing in the EEPM may be accountable for the anti-cancer activities.
Background: The south Indian Telugu states will celebrate a new year called ‘Ugadi’ which is a south Indian traditional festival. The ingredients used in ugadi pachadi have often also been used in food as well as traditional Ayurveda and Siddha medicinal preparations. Coronaviruses (CoVs) are a diverse family of enveloped positive-sense single-stranded RNA viruses which can infect humans and have the potential to cause large-scale outbreaks. Objective: Considering the benefits of ugadi pachadi, we investigated the binding modes of various phytochemical constituents reported from its ingredients against five targets of SARS-CoV-2. Methods: Flexible-ligand docking simulations were achieved through AutoDock version 1.5.6. Following 50ns of molecular dynamics simulation using GROMACS 2018.1 software and binding free energy (ΔGbind) of the protein-ligand complexes were calculated using the g_mmpbsa tool. ADME prediction was done using Qikprop of Schrodinger. Results: From the molecular docking and MM/PBSA results compound Eriodictin exhibited the highest binding energy when complexed with nucleocapsid N protein (6M3M) (-6.8 kcal/mol, -82.46 kJ/mol), bound SARS-CoV-2-hACE2 complex (6M0J) (-7.4 kcal/mol, -71.10 kJ/mol) and Mpro (6XR3) (-8.6 kcal/mol, -140.21 kJ/mol). Van der Waal and electrostatic energy terms highly favored total free energy binding. Conclusion: The compounds Eriodictin, Vitexin, Cycloart-3, 24, 27-triol, Agigenin, Mangiferin, Mangiferolic acid, Schaftoside, 27-Hydroxymangiferonic acid, Quercetin, Azadirachtol, Cubebin, Isomangiferin, Isoquercitrin, Malicarpin, Orientin and procyanidin dimer exhibited satisfactory binding energy values when compared with standard molecules. The further iterative optimization of high-ranked compounds following validation by in vitro and in vivo techniques assists in discovering therapeutic anti-SARS-CoV-2 molecules.
