"SJB2-043, first synthesized and reported in 2013, has been demonstrated to inhibit USP1 function, exhibiting cytotoxic effects on leukemic cells [17]."

reach
"We next determined whether SJB2-043 inhibits the DUB activity of native USP1 complexes isolated from human cells (XREF_FIG)."

reach
"SJB2-043 inhibited native USP1 in cells, and both compounds promoted the degradation of ID1, ID2, and ID3 in leukemic cell lines, leading to cell death that was partially caspase dependent."

reach
"SJB2-043 blocked the deubiquitinating enzyme activity of USP1 in vitro with an IC50 in the nanomolar range (Mistry et al., 2013)."

reach
"Additionally, SJB2-043 has been found to impede the maintenance of cancer stem cells and DNA damage repair by modulating USP1 activity [18]."

reach
"In addition, SJB2-043 inhibited the labeling of USP1 with Ub-VS in a dose dependent manner (XREF_SUPPLEMENTARY)."

reach
"USP1 inhibitor SJB2-043 inhibits the enzyme activity of native USP1."

reach
"These results demonstrate that USP1 inhibitor SJB2-043 inactivates native USP1 in primary AML cells and exhibits cytotoxicity."
