We recently reported that 3, 3-dimethyl-3H-benzofuro [3, 2, f][1]-benzopyran and its hydrogenated analogue are selective in vitro inhibitors of mycobacterial growth. However, their lack of in vivo activity on a murine model of Mycobacterium tuberculosis infection due to their poor bioavailability led to a structure–activity relationship investigation. We wish to report here the preparation of some structural analogues along with their biological effect ...
