Abstract :

We have designed, synthesized, and tested monocyclic ?²-lactams that carry aryl-thioether group at C4. These lactams have shown good intrinsic activity against serine ?²-lactamase producing Mycobacterium tuberculosis H37Rv (Mtb). Some of the compounds have demonstrated minimal inhibitory concentration (MIC) as low as 6.25 ?¼g/ml in 7H9 and 0.19 ?¼g/ml in GAST. Our investigations indicate that these compounds are cidal to both replicating and non-replicating persistent Mtb. These compounds have also shown activity against multi-drug resistant strains of M. tuberculosis. Therefore, they are promising candidates for lead discovery. Mechanism of action and target identification studies are currently underway.
