5,7-Dichloro-1,3-benzoxazole-2-thiol and its novel derivatives that have previously been synthesized in our laboratory are screened for in vitro antibacterial activity. In correlation to antibacterial activity, compounds are subjected to molecular docking studies with GlcN-6-P synthase. All the compounds showed good antibacterial activity. Among them, compounds 1, 4, and 5a emerged as good antibacterial agents without showing any resistance. In molecular docking studies all the molecules showed good inhibition with GlcN-6-P synthase. So, it can be predicted as inhibition of GlcN-6-P synthase may be responsible for antibacterial activity.
