  • 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.

  • Publication number: 20190196441
    Abstract: A method for controlling and adjusting a machining parameter of a processing machine detects and acquires information of workpieces during processing, and calculates an error compensation depending on the detected information and a mathematical model. The error compensation is compared with a first preset value and a determination made as to whether the error compensation is greater than a first preset value. The machining parameter is adjusted when the error compensation is not greater than the first preset value, the processing machine can be stopped if greater. An apparatus, and a non-transitory computer readable medium for controlling the machining parameter are also disclosed.
