Sample solution is provided at 25 µL, 10mM.
HSP27 inhibitor J2 (J2) is an inhibitor of HSP27, which significantly induces abnormal HSP27 dimer formation and inhibits HSP27 macropolymer production[1-3].
J2(10 µM J2;12 hr)showed stronger HSP27 cross linking activity in HSP27 high expressed lung cancer cells and relatively low cytoxicity[4].
J2(15 mg/kg; i.p; on every other day after irradiation for 14d) treatment significantly inhibited immune cell infiltration in lung tissue. J2-treated mice reversed radiation-induced respiratory distress. J2 inhibited IR-induced lung fibrosis in mice[5-6].
