  • PYRIDOPYRIMIDINE-BASED COMPOUND AND APPLICATION THEREOF
    Publication number: 20240132492
    Abstract: The present disclosure provides a class of Pyridopyrimidine compounds having a structure shown in Formula (I) or their pharmaceutically acceptable salts, or stereoisomers or prodrug molecules and applications thereof. The compounds in the present disclosure can efficiently and selectively degrade AKT3 protein in cells without affecting AKT1/2, thereby significantly inhibiting tumor cell proliferation mediated by high expression of AKT3 protein. It can be used to prepare therapeutic drugs for cancer and other diseases related to abnormal expression of AKT3 protein.

  • IS-IS high availability design
    Patent number: 7269133
    Abstract: The HA IS-IS system provides a redundant backup IS-IS protocol instance that can seamlessly assume the function of the active IS-IS instance in the event of active MCP failure. Once the backup is online, the active synchronizes its global, interface, adjacency, neighbor, and LSP system state information. In the ongoing synchronization phase, the active and the backup maintain synchronization using a combination of explicit message updates from active to backup together with message flow-through. In the recovery phase, the operating system detects the failure of the active and notifies the backup, which assumes the active function as a standalone system without reconfiguring or interrupting traffic among peer network routers, and starts computing forwarding tables and updating routing tables.
