Research use only, not for human use.

A novel potent ubiquitin-specific protease USP1 inhibitor with IC50 of 78.1 nM.

A novel potent ubiquitin-specific protease USP1 inhibitor with IC50 of 78.1 nM, 5 times more potent than SJB2-043 in promoting ID1 degradation and cytoxicity in K562 cells; also increases the levels of Ub-FANCD2 and Ub-PCNA, and decreases the HR activity; triggers apoptosis in multiple myeloma cells via activation of caspase-3/8/9, degrades USP1 and downstream inhibitor of DNA-binding proteins as well as inhibits DNA repair via blockade of Fanconi anemia pathway and homologous recombination; downregulates multiple myeloma stem cell Notch-1, Notch-2, SOX-4, and SOX-2, and induces generation of more mature and differentiated plasma cells.
