摘要:
The present disclosure provides heterocyclic compounds and use thereof, specially relates to a compound represented by Formula (I), a pharmaceutically acceptable salt thereof, a tautomer thereof, a stereoisomer thereof, a solvate thereof, a crystal form thereof, a metabolite thereof or a prodrug thereof, further relates to a PROTAC comprising a compound of Formula (I), a pharmaceutically acceptable salt thereof, a tautomer thereof, a stereoisomer thereof, a solvate thereof, a crystal form thereof, a metabolite thereof or a prodrug thereof. The heterocyclic compounds can be used for preventing or treating a SOS 1-associated disease.
A novelunsymmetrical structural class of HCV NS5A inhibitors showing picomolar range antiviral activity has been identified. An unsymmetrical lead compound 2, generated from a substructure of a known symmetrical inhibitor 1, was optimized by extension of its substituents to interact with the hitherto unexplored site of the target protein. This approach afforded novel highly potent unsymmetrical inhibitor
