| Abstract: | Protein kinases are important drug targets in human cancers, inflammation and metabolic diseases. Docking studies was
performed for all the benzimidazopyrimidine and coumarin substituted benzimidazopyridimine derivatives with human Aurora A
kinase target (3FDN) employing flexible ligand docking approach by using AutoDock 4.2. All the compounds were found to have
minimum binding energy ranging from -6.26 to -9.29 kJ/mol. Among the molecules tested for docking study, 10-(6-Bromo-2-oxo-
2H-chromen-4-ylmethyl)-2-isopropyl-10H-benzo4,5]imidazo1,2-a]pyrimidin-4-one (2k) showed minimum binding energy (-9.29
kJ/mol) with ligand efficiency of -0.31. All the ligands were docked deeply within the binding pocket region of 3FDN showing
hydrogen bonds with Ala 213 and Asn 261. The docking study results showed that these derivatives are excellent inhibitor of
human Aurora A kinase target; and also all these docked compounds have good inhibition constant, vdW + Hbond + desolv
energy with best RMSD value. |
