title: Synthesis of [difluoro-(3-alkenylphenyl)-methyl]-phosphonic acids on non-crosslinked polystyrene and their evaluation as inhibitors of PTP1B.
abstract: A series of [difluoro-(3-alkenylphenyl)-methyl]-phosphonates were prepared on non-crosslinked polystyrene, a soluble polymer support. After cleavage from the support, the resulting phosphonic acids were examined for inhibition with protein tyrosine phosphatase 1B. Compound 20, bearing an alpha,beta-unsaturated allyl ester moiety, was the most potent of this series of compounds, being a reversible, competitive inhibitor with a K(i) of 8.0+/-1.4 microM.
