Low molecular weight peptidomimetic compounds based on 0-malonyl tyrosine and 0-carboxymethyl salicylic acid are potent inhibitors of PTP1B. Modifications of the N-terminal Boc-Phe moiety were undertaken in an effort to improve physical chemical properties and to achieve cellular activity. Although Phe ultimately proved to be the optimal N-terminal amino acid, several viable replacements for the Boc group were identified, two of which afforded analogues that were effective at enhancing the insulin-stimulated uptake of 2-deoxyglucose by L6 myocytes.
