YCH3971 (0.01-10000 nM, 7 days) potently inhibits the proliferation of BRCA1-deficient MDA-MB-436 cells, with an IC50 of 2.10 nM[1].
YCH3971 (0.01-10000 nM, 7 days) inhibits the proliferation of BRCA2-deficient V-C8 cells with an IC50 of 69.61 nM, while it exhibits only extremely weak activity against BRCA2-proficient V79 cells[1].
YCH3971 (0.01-10000 nM, 7 days) inhibits the proliferation of BRCA1-mutant UWB1.289 ovarian cancer cells with an IC50 of 112.86 nM, whereas it shows almost no activity against UWB1.289 + BRCA1 cells with restored BRCA1 expression[1].
YCH3971 (0.01-1 μM; 48 h) induces dose-dependent DNA damage in MDA-MB-436 cells[1].
YCH3971 (0.01-1 μM; 3 days) induces dose-dependent G2/M phase arrest in MDA-MB-436 cells[1].
YCH3971 (0.01-1 μM; 4 days) induces dose-dependent caspase-mediated apoptosis in MDA-MB-436 cells[1].
