Description: UC-764864 is a UBE2N inhibitor. UC-764864 specifically blocked the E1-UBE2N thioester transfer in vitro. Treatment of MDS/AML cell lines and patient-derived primary cells with UC-764864 suppressed innate immune signaling and induced cytotoxic effects in MDS/AML cell lines and primary cells while sparing healthy hematopoietic cells in vitro and in vivo.

More Info: Inflammatory and innate immune signaling pathways are activated in leukemic stem and progenitor cells and contribute to the pathogenesis of hematologic malignancies, such as myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). UBE2N is a ubiquitin (Ub) conjugating enzyme that catalyzes lysine 63 (K63)-linked Ub chains on substrates that are critical for signal transduction of broad innate immune signaling pathways.
