  • Publication number: 20250138912
    Abstract: A method and system for using an interactive and intelligent tool to generate a connector is disclosed. In some embodiments, the method includes generating one or more first connector builder interfaces to receive user input for creating the connector. The method includes invoking one or more artificial intelligence (AI) models to automatically determine one or more suggestions of configuration parameters used in creating the connector based on the user input. The method also includes generating one or more second connector builder interfaces to present the one or more suggestions of configuration parameters to the user for acceptance or modification. The method includes creating the connector in a connector builder using the configuration parameters. The method further includes generating one or more third connector builder interfaces to enable the user to publish the connector.

  • Publication number: 20230248723
    Abstract: The present invention relates to novel therapeutic agents against hepatitis B virus (HBV) infection, particularly inhibitors of viral covalently closed circular DNA (cccDNA) which is the key barrier for HBV cure. Accordingly, the invention provides the pyrrolo[2,3-b]pyrazine compounds of formula (I), as described and defined herein, for use in the treatment of HBV infection. The compounds provided herein are highly potent against HBV infection and enable an improved therapy, particularly of chronic HBV infection and HBV rebound. The present invention further relates to a novel screening assay for the identification of therapeutic agents against HBV infection, particularly cccDNA inhibitors, which is performed in hepatocyte-like cells that recapitulate the complete HBV life cycle following infection with patient-derived HBV.
