(Z)-Mirin is an MRN (Mre11-Rad50-Nbs1) inhibitor. (Z)-Mirin prevents MRN-dependent activation of ATM without affecting ATM protein kinase activity. (Z)-Mirin inhibits Mre11-associated exonuclease activity. (Z)-Mirin increases apoptosis, triggers a G2/M checkpoint and strongly inhibits homology-directed repair (HDR).
(Z)-Mirin (50, 100, 500 μM) inhibits ATM-dependent phosphorylation of Nbs1 and Chk2 and the MRN-dependent autophosphorylation of ATM at Ser1981 in response to DNA double-strand breaks (DSBs). (Z)-Mirin (100 μM) inhibits Mre11 nuclease activity[1]. (Z)-Mirin (10-100 μM
24 h) shows 50% cytotoxicity at 50 μM in HEK293 cells[1]. (Z)-Mirin (10-100 μM) induces a substantial G2 arrest at concentrations of 50 μM and 100 μM[1]. (Z)-Mirin (18 µM
48 h) increases apoptosis in PEO4 cells[2].
