Background: Postprandial hyperglycemia considered to be a major risk factor for cerebrovascular complications. Objective: The current study was designed to elucidate the beneficial role of voglibose via in-silico in vitro to in-vivo studies in improving the postprandial glycaemic state by protection against strokeprone type 2 diabetes. Material and Methods: In-Silico molecular docking and virtual screening were carried out with the help of iGEMDOCK+ Pymol+docking software and Protein Drug Bank database (PDB). Based on the results of docking studies, in-vivo investigation was carried out for possible neuroprotective action. T2DM was induced by a single injection of streptozotocin (90mg/kg, i.v.) to neonates. Six weeks after induction, voglibose was administered at the dose of 10mg/kg p.o. for two weeks. After eight weeks, diabetic rats were subjected to middle cerebral artery occlusion, and after 72 hours of surgery, neurological deficits were determined. The blood was collected for the determination of serum glucose, CK-MB, LDH and lipid levels. Brains were excised for determination of brain infarct volume, brain hemisphere weight difference, Na+-K+ ATPase activity, ROS parameters, NO levels, and aldose reductase activity. Results: In-silico docking studies showed good docking binding score for stroke associated proteins, which possibly hypotheses neuroprotective action of voglibose in stroke. In the present in-vivo study, pre-treatment with voglibose showed a significant decrease (p<0.05) in serum glucose and lipid levels. Voglibose has shown significant (p<0.05) reduction in neurological score, brain infarct volume, the difference in brain hemisphere weight. On biochemical evaluation, treatment with voglibose produced significant (p<0.05) decrease in CK-MB, LDH, and NO levels in blood and reduction in Na+-K+ ATPase, oxidative stress, and aldose reductase activity in brain homogenate. Conclusion: In-silico molecular docking and virtual screening studies and in-vivo studies in MCAo induced stroke, animal model outcomes support the strong anti-stroke signature for possible neuroprotective therapeutics.

Objective: The significant drawbacks of chemotherapy are that it destroys healthy cells, resulting in adverse effects. Hence, there is a need to adopt new techniques to develop cancer-specific chemicals that target the molecular pathways in a non-toxic fashion. This study aims to screen pyrazole-condensed heterocyclics for their anticancer activities and analyse their enzyme inhibitory potentials EGFR, ALK, VEGFR and TNKS receptors. Methods: The structures of the compounds were confirmed by IR, NMR and Mass spectral studies. The in silico techniques applied in this study were molecular docking and pharmacophore modeling to analyse the protein-ligand interactions, as they have a significant role in drug discovery. Drug-likeness properties were assessed by the Lipinski rule of five and ADMET properties. Anticancer activity was performed by in vitro MTT assay on lung cancer cell lines. Results: The results confirm that all the synthesised pyrazole derivatives interacted well with the selected targets showing docking scores above-5 kcal/mol. Pyrazole 2e interacted well with all the four lung cancer targets with its stable binding mode and was found to be potent as per the in vitro reports, followed by compounds 3d and 2d. Pharmacophore modeling exposed the responsible features responsible for the anticancer action. ADMET properties reported that all the compounds were found to have properties within the standard limit. The activity spectra of the pyrazoles predicted that pyrazolopyridines (2a-2e) are more effective against specific receptors such as EGFR, ALK and Tankyrase. Conclusion: Thus, this study suggests that the synthesised pyrazole derivatives can be further investigated to validate their enzyme inhibitory potentials by in vivo studies.

Unknown Etiology

Parkinson’s disease (PD) is a common known neurodegenerative disorder with unknown etiology. It was estimated about 0.3% prevalence in the U.S population and enhance to 4 to 5% in older than 85 years. All studies were depending on the molecular docking where all ligands and protein PARK7 (PDB ID: 2RK3) were interacted by docked process. Some natural compounds was selected such as Harmine, Alloxan, Alpha spinasterol, Myrcene, and Vasicinone and PARK7 (PDB ID: 2RK3) protein. According to the PyRx and SWISS ADME result, Harmine was the only ligand which was showing minimum binding affinity. AutoDock Vina software was used for docking process between ligand (Harmine) and receptor protein PARK7 (PDB ID: 2RK3). The result was visualized under PyMol. Harmine was inhibiting the activity of PARK7 (PDB ID: 2RK3) and it may be used for the treatment of PD in future prospect after its in vitro and in vivo studies.

Tuberculosis is a type of ancient, chronic disease which affects humans and caused by Mycobacterium tuberculosis. They affect the lungs and other organs. The treatment is curable but in some cases it is fatal if not treated properly. The molecular docking method was used to see the interaction of the protein with the ligand. Thus, molecular docking was used to analyse the Rec A (PDB ID 1U94) target protein with their known type of ligand by using molecular docking tools. The Rec A (PDB ID 1U94) structure of protein was downloaded through online database. The best ligand after molecular docking was Quinolone, which may act as a drug after in vitro and in vivo studies.
