Colorectal cancer (CRC) is one of the deadly diseases which incidence rate will increase every year due to people lifestyle and food habit etc., Moreover, people’s required a new therapeutic molecule to resolve this problem. Therefore plant-based chemical constituents are the best option due to the low side effects, easy availability and cost-effective manner. The flowering plant of Thunbergia fragrans Roxb belongs to the Acanthaceae family has a vast range of medicinal properties, anticancer activity is one among them. Thunbergia fragrans has reported to had chemical constituents of Palmitic acid, Cis-9-Hexadecenal and Campesterol which possess anticancer activity. For the beginning of TF chemical constituents were studied against the Colorectal cancer (CRC) mutant genes such as NRAS (PDB ID: 6ZIZ), Beta-Catenin (PDB ID: 6M93) – Oncogenes; APC (PDB ID: 3NMX), Smad2 (PDB ID: 1KHU) – Tumor Suppressor genes through insilico docking studies. AutoDock 4.2 tool was used to predict the interaction between ligand and receptor, Binding energy and Bond specification in a 3D space. Finally, the results revealed TF chemical constituents showed excellent binding energy against CRC mutant genes such as Palmitic acid against Beta-Catenin (-4.75) and APC (-4.01), Cis-9-Hexadecenal against NRAS (-1.92), Beta-Catenin (-3.96) and APC (-4.41), Campesterol against Beta-Catenin (-8.55) and APC (-8.85) respectively.
