Adezmapimod (SB203580, RWJ 64809, PB 203580) 是一种p38 MAPK抑制剂，在THP-1细胞中IC50为0.3-0.5 μM，对SAPK3(106T)和SAPK4(106T)选择性低10倍，且阻断PKB磷酸化，IC50为3-5 μM。SB203580 可诱导线粒体自噬和细胞自噬。
| CAS No. | 152121-47-6 |
| 生物活性 | Adezmapimod (SB 203580) is a selective and ATP-competitive p38 MAPK inhibitor with IC50s of 50 nM and 500 nM for SAPK2a/p38 and SAPK2b/p38β2, respectively. Adezmapimod inhibits LCK, GSK3β and PKBα with IC50s of 100-500-fold higher than that for SAPK2a/p38. Adezmapimod does not disrupt JNK activity and is an autophagy and mitophagy activator. |

| 体内研究 | Adezmapimod (SB 203580) (5 mg/kg/day; intra peritoneal injected daily for 16 consecutive days, in female atymic Nu/Nu mice) treatment, p38WT tumors show a significantly smaller tumor burden when compared with p38TM tumors that were treated in parallel. |
| 体外研究 | Adezmapimod (SB 203580) (preincubated with 0-30 μM for 1 h and cultured for 24 h in the presence of 20 ng/mL IL-2) prevents the IL-2-induced proliferation of primary human T cells, murine CT6 T cells, or BAF F7 B cells with an IC50 of 3-5 μM. SB203580 blocks PKB phosphorylation (IC50 3-5 μM). SB203580 inhibitsthe phosphorylation of Ser473 in a dose-dependent manner in both CT6 and activated human T cells and IL-2-responsive BA/F3 F7 B cells. |
