Background: Infections caused by drug resistant microorganisms have been increasing worldwide thereby being one of the major causes of morbidity in the 21st century. Klebsiella pneumoniae is one such bacteria causing lung inflammation, lung injury and death. Emergence of hyper-virulent and drug resistant species such as ESBL and CRKP has made this microbe a serious and urgent threat. The pace of emergence of these species is outgrowing the development of novel drug and vaccine candidates thereby focusing on drug repurposing approach. Objective: 1. Homology Modelling of Thymidylate Synthase. 2. Verification of Modelled Structure. 3. Molecular Docking. 4. Molecular Dynamic Simulation of Docked Complex. 5. In vitro analysis of 5-FU activity against Klebsiella pneumonia. Method: The 3-D structure of Thymidylate Synthase was predicted using Swiss-Model server and validated by in silico approaches. - Determination protein-protein interactions using STRING database. - Molecular docking. - MD simulations of 5-FU with predicted structure of thymidylate synthase. - In vitro antimicrobial drug sensitivity assay at different concentrations. Result: Hydrogen bond was observed in Molecular Docking - Protein-ligand complex remains stable during simulation. - 5-FU shows antimicrobial activity against Klebsiella pneumonia during In vitro study. Conclusion: Both In silico as well as in vitro analysis have indicated that 5-FU can potentially be developed as an antimicrobial agent towards Klebsiella pneumonia

In Silico Admet

Plasmodium falciparum adenylosuccinate lyase ( PfADSL) is an important enzyme in purine metabolism. Although several benzimidazole derivatives have been commercially developed into drugs, the template design as inhibitor against PfADSL has not been fully explored. This study aims to model the 3-dimensional (3D) structure of PfADSL, design and predict in silico absorption, distribution, metabolism, excretion and toxicity (ADMET) of 8 substituted benzo[ d]imidazol-1-yl)methyl)benzimidamide compounds as well as predict the potential interaction modes and binding affinities of the designed ligands with the modelled PfADSL. PfADSL 3D structure was modelled using SWISS-MODEL, whereas the compounds were designed using ChemDraw Professional. ADMET predictions were done using OSIRIS Property Explorer and Swiss ADME, whereas molecular docking was done with AutoDock Tools. All designed compounds exhibited good in silico ADMET properties, hence can be considered safe for drug development. Binding energies ranged from −6.85 to −8.75 kcal/mol. Thus, they could be further synthesised and developed into active commercial antimalarial drugs.

Life Threatening

The entire human population is under treat of SARS-Cov-2 virus causing life threatening complicacies. Three proteins namely papain-like protease (PLpro), 3C-like protease (3CLpro) and spike protein isolated from the virus have been targeted for formulating the antiviral medicament. Ayurvedic medicinal plants with established antiviral efficacy are great choice to design immediate treatment strategies in this trying time. Here, 9 active molecules from ayurvedic medicinal plant resources were selected, out of which only 6 have screened through ADME analysis and molecular docking was performed with the three viral proteins to understand their antiviral performances in in silico model. Outcome of this study will surely open up a floodgate of thousand new possibilities in exploiting the existing natural herbs in COVID 19 treatments.
