In this study, the aqueous and ethanol extracts of Musa sapientum peel and pulp were investigated for phytochemical screening and antioxidant activity. Antimicrobial activity and Minimal Inhibitory Concentration (MIC) were analyzed against three different microbial pathogens. From the reported GCMS analysis, the selected compounds were subjected to anti-cancer activity against breast cancer using in silico study. The highest antioxidant activity, presence of secondary metabolites and microbial activity were observed in a significant range. MIC examination revealed that the three different microbial pathogens were sensitive for the peel extract. . In silico study, out of 7 selected compounds, 4 compounds exhibit the highest docking score, binding free energy and acceptable pharmaceutical properties. Molecular dynamics simulation was performed for the top two compounds and the resulting analysis explained the protein-ligand stability and the results concluded that the lead compounds possess the highest stability. From this study, it was concluded that the selective bioactive compounds from Musa sapientum peel exhibited significant antioxidant and antimicrobial activity through in vitro analysis and also the bioactive compounds possessed anti-cancer property which was revealed by in silico investigation.

Abstract Drug delivery in a safe manner is a major challenge in the drug development process. Growth factor receptors (GFRs) are known to have profound roles in the growth and progression of cancerous cells making these receptors a therapeutic target in the effective treatment of cancer. This work focused on exploring bioactive compounds that can target GFRs usingin-silico method. In this study, 50 bioactive compounds from different plant sources were screened as anticancer agent against GFRs using drug likeness parameters of Lipinski’s rule of five. The molecular docking was performed between phytochemicals and GFRs. Ligands with acceptable drug likeness and binding energy comparable to the standard drugs were further screened to determine their pharmacokinetic activities. This study showed phytochemicals with the binding energy comparable with the standard drugs (Dovitinb and Geftinib), while ADME, bioactivity score and bioavailability radar analysis gave further insight on these compounds as potent anticancer agents.

Breast cancer on becoming one of the leading cancer types, emerged as an important barrier in increasing life expectancy of the overall population. In the current study, some compounds were screened based on literature survey for the identification of natural bioactive compounds as potential inhibitors of Lyn tyrosine kinase. Therefore, a multi-step molecular docking was carried out using AutoDock embedded in the MGL Tools. After initial screening, molecules having a higher docking score and binding free energy compared to Tamoxifen were considered for further assessment. Some already known synthetic lyn tyrosine kinase inhibitor have been used for better understanding of the comparative study. Based on in silico Lipinski filter analysis, toxicity prediction, pharmacokinetic analysis, four compounds were proposed to be promising inhibitors of Lyn tyrosine kinase. Furthermore, the binding interactions of all proposed inhibitors of Lyn showed strong ligand efficiency in terms of energy score obtained with the help of molecular modelling analyses. Hence, the proposed compounds out of which three are bioactive compounds might be taken forward as potential next-generation Lyn kinase inhibitors for managing Lyn associated breast cancer after experimental authentication.

Background: Small molecule compounds are docked into receptor binding sites and the binding affinity of the complex is calculated using the structure-based drug design technique. Precise and quick docking processes, as well as the capacity to examine binding geometries and interactions, are required for a full knowledge of the structural principles that influence the strength of a protein/ligand complex. The present work deals with in-silico molecular docking studies of some heterocyclic compounds such as benzoxazole, benzimidazole, imidazole and tetrazole against the EGFR tyrosine kinase receptor. Methodology: Molecular docking studies of some heterocyclic compounds such as benzoxazole, benzimidazole, imidazole and tetrazole against the EGFR tyrosine kinase receptor using Schrodinger LLC (Maestro 9.2) software. Results: Our in silico observations reveal that, all the selected heterocyclic compounds (1-8) show good binding interaction and good docking score against selected target enzyme. Out of eight compounds selected for the study two compounds compound 3 and 7 shows higher glide score. Compound 3 binded to ASP855 with a docking score of −11.20 kcal/mol. Compound 7 binded to ASP855 with a docking score of −11.56kcal/mol. Conclusion: Docking results revealed that compounds (1-8) interact with EGFR kinase receptor active site. Among the compounds, compound 7 has shown the highest glide score of -11.56 kcal/mol.
