| 产品描述: | SC99 is an orally active, selective STAT3 inhibitor targeting JAK2-STAT3 pathway. SC99 docks into the ATP-binding pocket of JAK2. SC99 inhibits phosphorylation of JAK2 and STAT3 with no effects on the other kinases associated with STAT3 signaling. SC99 inhibits platelet activation, aggregation and displays potent anti-myeloma, anti-thrombotic activities |
| 靶点: |
STAT3;JAK2 |
| 体外研究: |
SC99 (10 or 30 μM; for 72 hours) induces MM cell death.
SC99 (10 μM; 24 hours) decreases the p-STAT3 level but has no effects on total STAT3 expression. SC99 (2.5, 5, 10, 20 μM; for 60 mins) inhibits JAK2 phosphorylation in a concentration-dependent manner but does not inhibit the phosphorylation levels of AKT, ERK, mTOR or c-Src at a concentration up to 20 μM.
SC99 (1.25, 2.5, 5 μM; pre-treated for 10 min) inhibits collagen (2 μg/mL) and thrombin (0.02 U/mL) induced phosphorylation of STAT3 in a concentration-dependent manner.
SC99 (pre-treated for 2 hours) inhibits IL-6 (50 ng/ml; for 20 min) induced STAT3 nuclear translocation in OPM2 cells. |
| 体内研究: |
SC99 (30 mg/kg; orally; daily; for continuous 14 or 28 days) delays myeloma tumor growth in xenograft mice models. SC99 (5, 10, 15 mM, 15 μL; ICV) produces an effective inhibitory effect on the phosphorylation of JAK2 and STAT3 in middle cerebral artery occlusion and reperfusion (MCAO/R) model (adult male SD rats; 250-300 g). SC99 ameliorates neuronal apoptosis and degeneration, neurobehavioral deficits, inflammatory response and brain edema. Animal Model: Nude mice with Human MM cells OPM2 or JJN3 Dosage: 30 mg/kg Administration: Orally; daily; for continuous 14 or 28 days Result: Delayed myeloma tumor growth in xenograft mice models and suppressed tumor growth more than 40% in 14 days in the OPM2 model. |
