ATR/PARP1-IN-1
ATR/PARP1-IN-1 is a potent ATR and PARP1 dual inhibitor with IC50s of 17.3 nM and 0.38 nM, respectively. ATR/PARP1-IN-1 effectively reduces cell viability, induces apoptosis and DNA damage. ATR/PARP1-IN-1 significantly impairs triple-negative breast cancer (TNBC) colony formation, migration, and invasion. ATR/PARP1-IN-1 suppresses tumor growth effectively in MDA-MB-468 xenografted mice, with no significant body weight change.

ATR/PARP1-IN-1 (Compound B8) shows anti-proliferation activity in TNBC cells with IC50s of 1.89 μM (MDA-MB-231), 0.32 μM (MDA-MB-468), 0.009 μM (MDA-MB-436)[1].
ATR/PARP1-IN-1 (0.5-1 μM, 48 h) induces G2/M cell cycle arrest in MDA-MB-231 cells and MDA-MB-468 cells, with a significantly stronger effect than the combination of Ceralasertib (AZD6738) (HY-19323) and Olaparib (HY-10162)[1].
ATR/PARP1-IN-1 (0.5-1 μM, 72 h) demonstrates a markedly stronger capacity to induce apoptosis than the combination of AZD6738 and Olaparib in MDA-MB-231 and MDA-MB-468 cells as determined by Annexin V/PI staining assay[1].
ATR/PARP1-IN-1 (0.5-1 μM, 10 days) exhibits a significantly greater inhibitory effect on the colony formation rate, migration, and invasion in both MDA-MB-231 and MDA-MB-468 cells compared to either treatment of AZD6738 or Olaparib administered alone, or their combination[1].
ATR/PARP1-IN-1 (1-2 μM, 48 h) interferes with the Epithelial-mesenchymal transition (EMT) of MDA-MB-468 cells[1].
ATR/PARP1-IN-1 (0.5-1 μM, 48 h) induces significant DNA damage in MDA-MB-231 cells and MDA-MB-468 cells[1].
ATR/PARP1-IN-1 (1-2 μM, 48 h) suppresses CHK1 phosphorylation through ATR inhibition in MDA-MB-468 cells[1].
