Abstract | In an effort to develop new and potent agents for therapy against tuberculosis, a high-throughput screen was performed against Mycobacterium tuberculosis strain H37Rv. Two 6-aryl-5,7-dimethyl-4-phenylcoumarin compounds 1a and 1b were found with modest activity. A series of coumarin derivatives were synthesized to improve potency and to investigate the structure-activity relationship of the series. Among them, compounds 1o and 2d showed improved activity with IC90 of 2 μM and 0.5 μM, respectively. Further optimization provided compound 3b with better physiochemical properties with IC90 0.4 μM which had activity in a mouse model of infection. The role of the conformation of the 4- and 6-aryl substituents is also described. |
