A variety of benzofurans and indole derivatives some with an alkynyl linker are disclosed herein. These compounds are not highly charged at physiological pH and have good bioavailability characteristics. These compounds exhibit selective or at least preferential affinity for the active sites of various sub-sets of protein tyrosine phosphatases. Some of these compounds are excellent inhibitors of
Mycobacterium
protein tyrosine phosphatase B (mPTPB) a protein tyrosine phosphatase expressed in
Mycobacterium tuberculosis
and characterized as a virulence factor in the causal agent of tuberculosis. Accordingly, many of these compounds and pharmaceutically acceptable salts thereof are useful for the treatment of diseases such as tuberculosis.

Focused on Mtb: A facilehydroxyindolecarboxylicacidbasedfocused amide library was designed to target both the PTP active site and a unique nearby pocket for enhanced affinity and selectivity. HTS of the library led to the identification of a highly potent and selectiveinhibitor, 11 a, of mPTPB, an essential virulence factor for Mycobacterium tuberculosis. Compound 11 a shows high cellular activity
