Title Synthetic methodology for the synthesis of octahydroquinazolinone and antibacterial agents against X. campestris pvs, P. syringae and P. carotovorum. Type Presentation Keywords In vitro, antibacterial activity, X. campestris pvs, P. syringae, P. carotovorum. Abstract In vitro antibacterial assay was performed against X. campestris pvs, P. syringae and P. carotovorum by using the disc diffusion method. The results obtained as zone of inhibition (mm) are presented. Tetracycline was used as standard drugs for the assay. The concentration used for the test compounds and that of the standard drugs remains the same. Researchers ali akbari (First researcher)
