LysRs inhibitor 2 is primarily utilized in research settings to study the role of lysyl-tRNA synthetase (LysRS) in various biological processes. It is particularly valuable in understanding the enzyme's involvement in cellular signaling pathways and its potential connection to diseases such as cancer and viral infections. By inhibiting LysRS, researchers can explore its impact on amino acid metabolism, protein synthesis, and non-canonical functions like immune response modulation. This compound is also used in drug development studies aimed at targeting LysRS for therapeutic interventions, especially in conditions where dysregulation of this enzyme plays a critical role. Its application extends to investigating antiviral strategies, as LysRS is implicated in the replication mechanisms of certain viruses.
