Mirin is a potent Mre11-Rad50-Nbs1 (MRN) complex inhibitor. Mirin prevents MRN-dependent activation of ATM (IC50=12 μM) without affecting ATM protein kinase activity, and it inhibits Mre11-associated exonuclease activity. Mirin abolishes the G2/M checkpoint and homology-dependent repair in mammalian cells. Mirin prevents ATM activation in response to DNA double-strand breaks (DSBs) and blocks homology-directed repair (HDR) in mammalian cells[1].

| In Vitro | Mirin inhibits H2AX phosphorylation with an IC50 of 66 μM. Mirin also inhibits the ATM-dependent phosphorylation of the downstream targets Nbs1 and Chk2 and the MRN-dependent autophosphorylation of ATM at Ser1981 in response to DSBs. Mirin induces a substantial G2 arrest at concentrations of 50 μM and 100 μM. Mirin (10-100 μM) inhibits homology-dependent DNA repair in TOSA4 cells[1]. BRCA2-deficient cells also showed hypersensitivity to the Mre11 inhibitor Mirin[2]. |
