HJ-PI01 is primarily used as a selective inhibitor in biochemical research, particularly targeting specific protein-protein interactions involved in cellular signaling pathways. It has been applied in studies related to inflammation and immune response modulation due to its ability to disrupt key regulatory complexes. Researchers utilize HJ-PI01 in vitro to probe the mechanistic details of signal transduction, especially in pathways associated with autoimmune diseases and cancer progression. Its high specificity makes it a valuable tool for validating therapeutic targets without inducing broad cytotoxic effects. Additionally, HJ-PI01 serves as a lead compound in the development of more potent and stable analogs for potential pharmacological use.
