  • Publication number: 20210261602
    Abstract: Compounds of formula: are described herein. The compounds selectively complex copper and are therefore useful both abiotically for measuring and detecting small amounts of copper and, in biological systems, for treating diseases associated with inappropriate copper levels, such as Wilson's disease and gastric cancer.

  • Patent number: 10973835
    Abstract: A method is disclosed for altering the redox equilibrium of a transmembrane receptor-like protein tyrosine phosphatase (RPTP), particularly a type IIa RPTP, by chemically modulating the activity through contact of such an enzyme with a diaryl boron compound that preferentially reacts with an RPTP in an oxidized state (CyS-OH). This redox modulation is most readily observed and put to use by assaying the inhibition of the phosphatase activity of the RPTP. Such an assay can be carried out on an enzyme in vitro or by contacting the enzyme in a living organism (in vivo). A useful diaryl boron compound corresponds in structure to Formula I in which Ar-1, Ar-2, R1, R2, R3 and R4 are defined within. A pharmaceutical composition containing a useful diaryl boron compound is also disclosed, as are particularly preferred diaryl boron compounds.
