B (mPTPB) is a virulence factor secreted by the pathogen and mediates mycobacterial survival in macrophages by targeting host cell immune responses. Consequently, mPTPB represents an exciting new target to combat tuberculosis (TB) infection. We describe a medicinal chemistry oriented approach that transforms a benzofuran salicylic acid scaffold into a highlypotent (IC50 = 38 nM) and selective mPTPB

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.

Lymphoid-specific tyrosinephosphatase (LYP), a member of the proteintyrosinephosphatase (PTP) family of signaling enzymes, is associated with a broad spectrum of autoimmune diseases. Herein we describe our structure-based lead optimization efforts within a 6-hydroxy-benzofuran-5-carboxylic acid series culminating in the identification of compound 8b, a potent and selectiveinhibitor of LYP with a Ki
