| Description | I-138 is an orally active and potent reversible inhibitor of USP1-UAF1.I-138 induces mono-ubiquitination of FANCD2 and PCNA and inhibits USP1 auto-cleavage in cells. | 
| In vitro | I-138 (0.5 μM; 4 hours) eliminates USP1 autodeubiquitination in HAP-1 USP1 WT and knockout cells, induces monoubiquitination of FANCD2 and PCNA in MDA-MB-436 cells, and dose-dependently (0.01-10 μM; 10 days) inhibits the viability of MDA-MB-436 cells without affecting HCC1954 cells[1]. | 
| In vivo | I-138 (50 mg/kg/day; oral administration; for 41 days) shows USP1 inhibition and moderate antitumor activity in mice with MDA-MB-436 tumors. However, combining I-138 with the PARP inhibitor Niraparib is more effective at inhibiting BRCA1/2 mutant tumors in vivo[1]. |
