SJB3-019A is a potent and novel inhibitor of USP1 with IC50 value of 0.0781 μM .
Ubiquitin-specific protease 1 (USP1) is a deubiquitinating (DUB) enzyme and removes polyubiquitin chains from the DNA binding 1 (ID1) protein, which plays an important role in the proliferation and progression of cancers, such as leukemia .
SJB3-019A is a potent and novel USP1 inhibitor. In K562 cells, SJB3-019A exhibited 5 times more potent than SJB2-043 in promoting ID1 degradation and cytoxicity. In HeLa cells, SJB3-019A increased the levels of Ub-PCNA and Ub-FANCD2 and reduced the homologous recombination activity .
