Mechanism of Action

Targets/IC₅₀/Ki	MRN ATM
In vitro	Mirin inhibits DSB-induced ATM activation, the ATM-dependent phosphorylation of the downstream targets Nbs1 and Chk2 and the MRN-dependent autophosphorylation of ATM at Ser1981 in response to DSBs. This compound also inhibits the G2 checkpoint in TOSA4 cells, and homology-dependent DNA repair in HEK293 cells. In cells with integrated HPV16 (SiHa), it sensitizes HPV episomes to PA25 resulting in a ∼5-fold reduction of the PA25 IC50. Pretreatment with this chemical also decreases cell viability and inhibits proliferating cell nuclear antigen expression in cisplatin-treated human embryonic kidney 293 cells.
Kinase Assay	Nuclease assay
Kinase Assay	Reactions with oligonucleotide nonhairpin substrates contains 25 mM MOPS (pH 7.0), 60 mM KCl, 0.2% Tween 20, 2 mM DTT, 1 mM or 5 MnCl₂ (or 5 mM MgCl₂, or 5 mM CaCl₂), 0.1 pmol of DNA substrate, and 0.3 pmol of Mre11 (or an equivalent amount of Mre11 complexed with Rad50) in a volume of 10 μl, and are incubated at 37°C for 30 min. SDS, EDTA, and proteinase K are then added to final concentrations of 0.2%, 5 mM, and 0.1 mg/ml, respectively, and incubated for another 15 min. 4 μl of each reaction is mixed with 4 μl of formamide loading buffer, and then loaded onto a sequencing gel containing 10% acrylamide and 7 M urea. After the run, each gel is analyzed using a phosphorimaging system. Reactions containing hairpin substrates are identical to those with nonhairpin substrates except that 3 pmol of this compound is added to reactions as indicated, and the reactions are incubated at room temperature overnight. Nonhomologous end-joining reactions contains 25 mM MOPS (pH 7.0), 60 mM KCl, 0.2% Tween 20, 2 mM DTT, 4 mM MgCl₂, 2 mM MnCl₂, 0.5 mM ATP, 4 ng of plasmid DNA, 10% polyethylene glycol, 0.01 pmol of human DNA ligase I, and 0.06 pmol of this chemical or 0.1 units of E. coli exonuclease III (GIBCO-BRL), in a volume of 10 μl. After incubation at 37°C for 25 min, Tween 20 is added to a final concentration of 0.5%, and a 2.5 μl aliquot is amplified by PCR using primers DAR5 and DAR147. PCR products are cloned using the TA cloning kit and sequenced using an automated ABI Capillary Genetic Analyzer.
In vivo	Mirin in nanoparticles resulted in a sharp impairment of tumor growth, associated with DDR activation, p53 accumulation, and cell death.
