Inhibition of Yersinia protein tyrosine phosphatase by calix[4]arene mono-, bis-, and tetrakis(methylenebisphosphonic) acids as well as calix[4]arene and thiacalix[4]arene tetrakis(methylphosphonic) acids have been investigated. The kinetic studies revealed that some compounds in this class are potent competitive inhibitors of Yersinia PTP with inhibition constants in the low micromolar range. The binding modes of macrocyclic phosphonate derivatives in the enzyme active center have been explained using computational docking approach. The results obtained indicate that calix[4]arenes are promising scaffolds for the development of inhibitors of Yersinia PTP.
Calix[4]arene and thiacalix[4]arene bearing phosphonic acid fragments at the wide rim of the macrocycle were found to be effective inhibitors of Yersinia protein tyrosine phosphatase with inhibition constant in the low micromolar range.Figure optionsDownload as PowerPoint slide
