产品描述 | Apremilast (CC-10004) (CC-10004) is a potent and orally active PDE4 (IC50=74 nM) with anti-inflammation activities. |
靶点活性 | PDE4:74 nM |
体外活性 | Apremilast通过抑制由脂多糖(LPS)引起的TNF-α释放,IC50为104 nM(pIC50=6.98±0.2),这一结果与之前报道的Apremilast对周围血单核细胞(PBMCs)的TNF-α抑制作用(IC50=110 nM)几乎完全一致,同时与Apremilast对PDE4酶抑制作用的效力相似(IC50=74 nM)。这些结果明确支持了Apremilast通过提高细胞内cAMP水平来抑制TNF-α的假设。PKA、Epac1和Epac2的敲除阻止了Apremilast对TNF-α的抑制和对IL-10的刺激[1]。 |
细胞实验 | Apremilast is solubilized in DMSO and stored, and then diluted with appropriate media (DMSO 0.025%) before use[1]. Raw 264.7 cells (100,000) are grown in 96-well plates. After 24 h, cells are stimulated with vehicle (final concentration of 0.025% DMSO) or with Apremilast at the indicated concentrations. After 30 minutes cells are stimulated with LPS 1 μg/mL for 4 h. When studying CGS21680 , SCH58261, ZM241385, BAY60-6583, or GS6201, the adenosine receptor ligands are added 15 minutes before Apremilast. Methotrexate is added 24 h and 1 h before Apremilast. Supernates are then collected and TNF-α levels are quantified with the Mouse TNF-α Quantikine ELISA Kit. IC50 (EC50) calculations are made using non-linear regression, sigmoidal dose-response, constraining the top to 100 % and bottom to 0 %, allowing variable slope, using GraphPad Prism v6.00[1]. |
