A variety of benzofurans and indole derivatives some with an acetyl 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. The lymphoid- specific tyrosine phosphatase (Lyp) has received enormous attention because of the finding that a single- nucleotide polymorphism (SNP) in the gene (PTPN22) encoding Lyp is associated with several autoimmune diseases, including type I diabetes. Many of these compounds and pharmaceutically acceptable salts thereof are novel therapeutic compounds useful for the treatment of various diseases including a number of autoimmune diseases.
