Used in research to study cancer cell signaling pathways, particularly in hematological malignancies such as leukemia and multiple myeloma. It acts as a deubiquitinase inhibitor, leading to the accumulation of ubiquitinated proteins and promoting apoptosis in tumor cells. Shows potential in overcoming drug resistance by targeting pathways involved in protein degradation. Also utilized to investigate the role of specific deubiquitinating enzymes in cellular processes and disease models. Not approved for clinical use; primarily a tool compound in preclinical studies.
