Protein-tyrosine phosphatase (PTP) inhibitors are attractive as potential signal transduction-directed therapeutics which may be useful in the treatment of a variety of diseases. We have previously reported the X-ray structure of 1,1-difluoro-1-(2-naphthalenyl)methyl] phosphonic acid (4) complexed with the human the protein-tyrosine phosphatase 1B (PTP1B) and its use in the design of an analogue which binds with higher affinity within the catalytic site (Burke, T. R., Jr. et al. Biochemistry 1996, 35, 15989). In the current study, new naphthyldifluoromethyl phosphonic acids were designed bearing acidic functionality intended to interact with the PTP1B Arg47, which is situated just outside the catalytic pocket. This residue has been shown previously to provide key interactions with acidic residues of phosphotyrosyl-containing peptide substrates. Consistent with trends predicted by molecular dynamics calculations, the new analogues bound with 7- to 14-fold higher affinity than the parent 4, in principal validating the design rationale.
