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

IC₅₀ & Target：

^{p38：50 nM (IC₅₀)}

p38β2：500 nM (IC₅₀)

體外研究(In Vitro)：

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[1].
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

Cell Line:CT6, BA/F3 cell line F7, and PBMC/T cells

Concentration:0-30 μM

Incubation Time:Preincubated with 0-30 μM SB203580 for 1 h and cultured for 24 h in the presence of 20 ng/mL IL-2

Result:Prevented 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.

體內研究(In Vivo)

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

Animal Model:Six-week-old female atymic Nu/Nu mice CAL27 p38WT and p38TM tumors

Dosage:5 mg/kg/day

Administration:Intra peritoneal injected daily for 16 consecutive days

Result:After 2 weeks treatment, CAL27 p38WT tumors were significantly smaller; CAL27 p38TM tumors were not affected by the p38 inhibitor (n=10).
