Molecular docking and molecular dynamics simulation of the anticancer active ligand from Mimosa pudica to the Fibronectin Extra Domain A (EDA).

Mimosa pudica was observed to have many useful characters the main aim of the experiment is to strengthen the multiple potential value of M. Pudica L. To study its secondary metabolites antioxidant, anti-cancerous, GCMS and in-silico studies. In general, the methanol method is employed for obtaining leaf extracts. The preliminary phytochemical screening of the M. pudica leaf extract showed the presence of bioactive components such as terpenoids, flavonoids, glycosides, alkaloids, quinines, phenols, tannins, saponins, and coumarins. An attempt is made to check the anticancer activity towards the cancer cell line A549 (Lung cancer cells) by MTT assay. For the identification of the compounds and to obtain its structure the crude extract is analyzed by GC-MS technique. The result of the GC-MS is analyzed using bioinformatics tool for in-silico docking to find out its targets against lung cancer receptors and PDB ID is obtained from the RCBS PDB database. The affinity of the identified ligand molecules to bind to the active site of the protein was studied through docking. And the effectiveness of the ligand molecules was obtained through molecular dynamics for longer simulation. The RMSD, RMSF and RG interaction were studied to the screened compounds. Further, MMPBSA analysis was carried out for the selected and standard drug like irigenin compounds. These selected lead molecules shown the better binding energy compare to irigenin drug in MMPBSA. The lead derivatives have shown potential results against lung cancer cell lines.
