Objective: In the present study, a novel series of 1, 3, 4-thiadiazole derivatives were docked against the mycobacterium tuberculosis protein kinase G. 1, 3, 4–thiadiazole derivatives with a modified primary amine group at 5th position were used for docking studies.Methods: The three-dimensional structure of the protein was obtained from PDB, and its active sites were predicted. The structures of all the compounds were drawn using chemdraw software version 8.0. The docking studies were done by using schrödinger software against the enzyme protein kinase G. Totally eighteen compounds was synthesized based on glide scoreResults: In this Docking study the thiadiazole analogues were showing good binding energy. The amino acids residues GLU588, SER412, GLY410 and GLU 628 in the kinase domain active site form hydrogen bonds with the ligand.Conclusion: The compounds D34, D16, D7, D25, D15, and D27 showed better interaction with protein kinase G (pknG) more than the other drug molecules
