  • Publication number: 20240317729
    Abstract: The present invention relates to bifunctional compounds, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present invention. In particular, the present invention is directed to compounds, which contain on one end a VHL ligand which binds to the ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. The present invention exhibits a broad range of pharmacological activities associated with compounds according to the present invention, consistent with the degradation/inhibition of targeted polypeptides.

  • Patent number: 11158629
    Abstract: The invention aims for a polarisation circuit of a power component comprising a capacitive dividing bridge and a resistive dividing bridge formed on the same substrate as the component. An additional electrode 1? in the front face 100 of the substrate makes it possible to adjust one of the capacitance values of the capacitive dividing bridge according to the other of the capacitance values coming from one of the electrodes of the power component. The sizing of this additional electrode furthermore makes it possible to obtain a leakage resistance contributing to the resistive dividing bridge. Alternatively, two additional resistances R, R? formed in the front face of the substrate making it possible to obtain the resistive dividing bridge independently of the capacitive dividing bridge.
