Delivering a potential drug is a predominant challenge in medicinal chemistry.in this study, bio organic compounds of Cymbopogon citratus was screened by analysing physiochemical properties like solubility, permeability, efficacy, toxicity, and metabolic stability. The optimization of drug potential against virulent protein was calculated by using docking algorithm Autodock 4.2.3. Structure based ligand docking reveals that the compounds having better inhibition potential against virulent enzymes with insoluble and impermeable activities. The organic compounds of Cymbopogon citratus were screened using Lipinski rule of five and ADME/T prediction for drug likeliness. The structure based ligand docking was done between bioactive compounds of plant and virulent protein that cause diseases. The interaction was visualized using Discovery studio and was studies. The molecular docking of bioactive compounds resulted in better inhibition potential with controlled lipophilicity level, without causing toxicity that harms the natural habitat of humans. The compounds, 1,3,4-trimethyl -3cyclohexene-1-carboxaldehyde exhibit binding energy -4.70 Kcal/mol followed by β-myrcene – 4.35 Kcal/mol and Geraniol -4.35 Kcal/mol. Hence, structure based ligand docking and in silico ADME/T studies revealed that the compounds have better inhibition potential against Apolipoprotein by improving the prediction of drug compounds.

Abstract: Malaria is one of the major disease of concern worldwide especially in the African regions. According to the recent WHO reports, African regions share 95% of the total deaths worldwide that occurs due to malaria. Plasmodium falciparum M17 Leucyl Aminopeptidase (PfM17LAP) plays an important role in the regulation of amino acids release and for the survival of the parasite. We performed molecular docking and simulation studies to find the potential inhibitors against PfM17LAP using ChEMBL antimalarial library. Molecular docking studies and post-docking analysis revealed that molecules CHEMBL369831 and CHEMBL176888 showed better binding than the reference molecule BESTATIN. LibDock and X-SCORES of molecules BES, CHEMBL369831 and CHEMBL176888 are 130.071, 230.38, 223.56 and -8.75 Kcal/mol, -10.90 Kcal/mol, -11.05 Kcal/mol respectively. ADMET profiling of the top ten ranked molecules was done by using the Discovery Studio. Molecular dynamic studies revealed that the complex PfM17LAP-CHEMBL369831 is stable throughout the simulation. Finally, we have reported novel inhibitors which possess more binding affinity towards PfM17LAP. Key words: Malaria, M17 Leucyl Aminopeptidase, ADMET, X-SCORE

Various invitro and computational methods were implemented to evaluate the anticancer potential of anthocyanidins, namely cyanidin, malvidin, delphinidin, peonidin, pelargonidin, and petunidin. These anthocyanidins were docked with CDK-2, CDK-6 and IGF-1R kinase proteins. Additionally, known inhibitors (KIs) such as SU9516, Palbociclib, OSI-906 are compared with their respective macromolecules, including, CDK-2, CDK-6 and IGF-1R kinase, in to compare results of the study based on Lipinski rule of 5.  The Auto Dock Tool (Autodock 4) was used for molecular docking, and the docked complex compounds were visualised and interpreted using the Bio via Discovery Studio 2020 client. The Docking results obtained showed a very good inhibitory binding to almost all the selected cancer proteins, and these compounds might be a potential drug molecule.

It is known that tomato (Lycopersicon esculentum) contains bioactive compounds to combat type-2 diabetes. Therefore, it is of interest to document data from the molecular docking analysis of compounds from Lycopersicon esculentum with the insulin receptors to combat type-2 diabetes. We report the binding features of cinnamicacid, chlorogenicacid, gallicacid & glucoside with insulin receptors for further consideration.

COVID-19, a new strain of coronavirus (CoV), was identified in Wuhan, China, in 2019. No specific therapies are available, and investigations regarding COVID-19 treatment are lacking. Crystallised COVID-19 main protease (Mpro), which is a potential drug target. The present study aimed to assess drugs found in literature as potential COVID-19 Mpro inhibitors, using a molecular docking study. Molecular docking was performed using Autodock 4.2, with the Lamarckian Genetic Algorithm, to analyse the probability of docking. The docking was cross-validated using Swiss Dock. COVID-19 Mpro was docked with several compounds, and docking was analysed by Biovia Discovery Studio 2020. Quinine and hydroxychloroquine were used as standards for comparison. The binding energies obtained from the docking of 6LU7, 2GTB with screened drugs viz., Quinine, Artesunate, Clotrimazol, Artemether, Quercetin, Mefloquine, ciprofloxacin, clindamycin, cipargamin, SJ-733 were in between -7.0 to -9.6 kcal/mol. On consideration of similar binding energy obtained from Autodock vina and SWISSDock and interaction residue pattern specifically (GLU 166,CYS 145, CYS44 and MET 49 residue) for SJ-733 & JPC-3210 may represent potential treatment options, and appeared to have the best potential to act as COVID-19 Mpro inhibitors. However, further research is necessary to investigate their potential medicinal use against CoV.
