PA-824 (1) and the derivatives examined in the present study. When referring to the imidazole ring, the numbering shown for PA-824 is used for consistency with previous work. Derivatives at the 2-position of the imidazole (2X-824) and at the 6-position of the imidazo-oxazine (6X-824) are investigated here.
