USP1-IN-15
USP1-IN-15 is an orally active and selective USP1 inhibitor with an IC50 of 12.3 nM. USP1-IN-15 has a high specificity for USP1 with negligible inhibition against all off-target DUBs. USP1-IN-15 suppresses colony formation, induces S-phase arrest, and stabilizes ubiquitinated PCNA. USP1-IN-15 also shows synergistic antiproliferative activity. USP1-IN-15 achieves significant tumor growth inhibition in vivo. USP1-IN-15 can be used for BRCA-mutated breast cancer.

Biological Activity

USP1 12.3 nM (IC50) |
USP1-IN-15 (compound 43) (14 days) balances profile of potent antiproliferative activity with IC50 = 0.07 μM in MDA-MB-436 and good metabolic stability (t1/2 value exceeding 120 min) [1].
USP1-IN-15 (1 μM) has a high specificity for USP1 with negligible inhibition against all off-target DUBs (USP5, USP7, USP8, USP9X, USP14, USP15, USP25, USP28, BAP1, and OTUD1) [1].
USP1-IN-15 (0-1000 nM, 0-168 h) dose-and time-dependently potently and persistently inhibits the deubiquitination of proliferating cell nuclear antigen (PCNA) and induces protein level of p-H2AX in MDA-MB-436 breast cancer cells[1].
USP1-IN-15 (100-1000 nM, 48 h or 2-3 weeks) induces S-phase arrest in MDA-MB-436 breast cancer cells[1].
USP1-IN-15 (0.1-10 μM, 7 days or 2-3 weeks) dose dependently enhances growth inhibition compared to monotherapy when combined with Olaparib (HY-10162) in MDA-MB-436 cells[1].
USP1-IN-15 (1 μM, 48 h) has superior synergistic activity when combined with Olaparib through enhanced induction of DNA damage and cell cycle arrest in MDA-MB-436 cells[1].
