Molecular docking and DFT calculation have been investigated for the synthesized oxazine derivatives. Theoretical calculations including DFT study has investigated and proved the reactivity of compound 4 is the greatest among others as follow 4>2>5>3>1. On the other hand, the stability of compounds has been calculated to prove that compound 1 has the highest stability among others as follow 1>3>5>2>4. Antibacterial activity test was confirmed potent activity for all the synthesized derivatives against E. coli and S. aureus bacterial strains. The synthesized compounds including 2, 4 and 5 showed potent inhibitory activity against both bacterial strains compared to positive reference of tetracycline. Docking study revealed that oxazine derivatives with 4-chlorobenzamide group at position number 2 showed higher potency than tetracycline as antibacterial by inhibiting TetR
