Mirin is an MRN-ATM pathway inhibitor blocking 3’ and 5’ exonuclease activity associated with Mre11, inducing G2 cell cycle arrest. | [Biological Activity]
mirin is a potent mrn complex inhibitor. mirin inhibits mre11-associated exonuclease activity, rather than alters dna-binding or mrn complex formation. moreover, mirin prevents mrn-dependent activation of atm in response to dna double-strand breaks, with an ic50 value of 12 μm. the mrn complex acts as a dna damage sensor, responsible for maintaining genome stability during dna replication, promoting homology-dependent dna repair and activating atm. the mrn-atm pathway plays an essential role in sensing and signaling from dna double-strand breaks.1. dupré a, boyer-chatenet l, sattler rm, et al. a forward chemical genetic screen reveals an inhibitor of the mre11-rad50-nbs1 complex. nature chemical biology, 2008, 4(2): 119-125. | [Synthesis]
GENERAL METHODS: (Z)-2-Amino-5-(4-hydroxybenzylidene)thiazol-4(5H)-one was synthesized from p-hydroxybenzaldehyde and pseudothioglycolide. The procedure was as follows: a mixture of p-hydroxybenzaldehyde (300 mg), pseudothioglycolide (1.1 eq.) and sodium acetate (3.0 eq.) was heated and refluxed for 3 to 7 hours under acetic acid (4 mL/1 g sodium acetate) as a solvent. Upon completion of the reaction, the reaction mixture was cooled and water was added to precipitate the product. The precipitate was collected by filtration and washed with water, dichloromethane and/or ethyl acetate depending on the physical properties of the starting material to finalize the target product. The product was an orange solid with a reaction time of 3 hours, a yield of 61.8% and a melting point of over 300 °C. The structure of the product was determined by 1H NMR (500 MHz, DMSO-d6) δ 10.10 (s, 1H), 9.29 (brs, 1H), 9.04 (s, 1H), 7.49 (s, 1H), 7.40 (d, 2H, J = 9.0 Hz), 6.88 (d, 2H, J = 8.5Hz); 13C NMR (100 MHz, DMSO-d6) δ 181.4, 176.1, 159.6, 132.1, 130.2, 126.0, 125.5, 116.8; and mass spectrometry (ESI) m/z 219 ([M-H]-) were confirmed. | [storage]
