| Summary: | Ras gene is frequently mutated in cancer. Among different subtypes of Ras gene, K-Ras mutation occurs in nearly 30 % of human cancers. K-Ras mutation, specifically K-Ras (G12D) mutation is prevalent in cancers like lung, colon and pancreatic cancer. During cancer occurrence, mutant Ras remain in activated form (GTP bound state) for cancer cell proliferation. In the quest for a potential K-Ras inhibitor, nitrogen-containing indazole derivatives can show promise as inhibitors, as they have numerous therapeutic properties like anti-inflammatory, anti-viral and anti-tumor. Furthermore, among various indazole derivatives, “Bindarit” is an important therapeutic compound which could have potential inhibitory action against K-Ras due to its structural resemblance with reference compound “Benzimidazole”. So, the current study is an attempt to find out the inhibitory effect of Bindarit against K-Ras activation by binding to a pocket which is adjacent to the switch I/II regions of the K-Ras receptor. AutoDock tool was used to investigate the binding affinity of protein ligand interaction and GROMACS package was utilised to assess their interactions in a dynamic setting. Bindarit shows better binding affinity than reference with binding energy of −7.3 kcal/mol. Upon ligand binding conformational changes take place, which could lead to the loss of GTPase activity. Consequently, further downstream signalling of the K-Ras pathway would be blocked and this could lead to the inhibition of K-Ras dependent cancer cell proliferation. However, further validation of present study can be done through experimental assay such as cytotoxic and protein expression analysis. |
