  • RIFAMYCIN ANALOGS AND ANTIBODY-DRUG CONJUGATES THEREOF
    Publication number: 20230285581
    Abstract: The disclosure relates to rifamycin analog compounds, intermediates and precursors thereof, and pharmaceutical compositions capable of inhibiting bacterial growth (e.g., S. aureus growth) and treating bacterial infections (e.g., S. aureus infections). The disclosure further relates to antibody-drug conjugates of rifamycin analog compounds and antibodies, for example, antibodies specific for infectious disease-related targets such as membrane glycoprotein receptor (MSR1), wall teichoic acids (WTA) or Protein A, and methods of use thereof to inhibit bacterial growth and treat bacterial infections.
    Type: Application
    Filed: December 28, 2022
    Publication date: September 14, 2023
    Applicant: Regeneron Pharmaceuticals, Inc.
    Inventors: Thomas NITTOLI, Seungyong Sean CHOI, Mrinmoy SAHA

  • Low leakage transient overvoltage protection circuit using a series connected metal oxide varistor (MOV) and silicon controlled rectifier (SCR)
    Patent number: 10916939
    Abstract: Transient overvoltage suppression is provided by discharging through a Metal Oxide Varistor (MOV) and Silicon Controlled Rectifier (SCR) which are connected in series between power supply lines. The SCR has a gate that receives a trigger signal generated by a triggering circuit coupled to the power supply lines. A trigger voltage of the triggering circuit is set by a Transil™ avalanche diode.
    Type: Grant
