High-throughput discovery of Mycobacterium tuberculosis protein tyrosine phosphatase B (MptpB) inhibitors using click chemistry.

A approximately 3500-member library of bidentate inhibitors against protein tyrosine phosphatases (PTPs) was rapidly assembled using click chemistry. Subsequent high-throughput screening had led to the discovery of highly potent (K(i) as low as 150 nM) and selective MptpB inhibitors, some of which represent the most potent MptpB inhibitors developed to date.
