HSP27 inhibitor J2 (Synonyms: J2) |
| Catalog No.GC38503 |
HSP27 억제제 J2(J2)는 HSP27 억제제로서 비정상적인 HSP27 이량체 형성을 유의하게 유도하고 HSP27 거대 중합체의 생성을 억제하여 HSP27의 샤페론 기능을 억제하고 이의 세포 보호 기능을 감소시키는 효과가 있다. HSP27 억제제 J2(J2)는 17-AAG의 항증식 활성을 현저하게 향상시키고 시스플라틴으로 유도된 폐암 세포 성장 억제를 민감하게 합니다.

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].
