4、reported TNF- inhibition by Apremilast on peripheral bloodmononuclear cells (PBMCs) (IC50=110 nM) and which is similar to the potency of Apremilast for PDE4enzymatic inhibition (IC50=74 nM). These results are clearly consistent with the hypothesis that Apremilastinhibits TNF- by increasing intracell

5、ular cAMP levels. PKA, Epac1 and Epac2 knockdowns prevented TNF-inhibition and IL-10 stimulation by Apremilast 1.體內(nèi)研究 Apremilast, orally administered (5 mg/kg), significantly inhibits TNF- production in the air pouch by 39 %(616 % of vehicle, P 1. Apremilast is a novel, oral PDE4 inhibitor that has

6、been shown to regulateinflammatory mediators. After oral administration of Apremilast, a mean maximum plasma concentration(Cmax) is found to be 67.0014.87 ng/mL. The plasma concentration of Apremilast decreases rapidly and iseliminated from plasma with a terminal half-life of 0.920.46 h 2PROTOCOLCel

7、l Assay 1 Raw 264.7 cells (100,000) are grown in 96-well plates. After 24 h, cells are stimulated with vehicle (finalconcentration of 0.025% DMSO) or with Apremilast at the indicated concentrations. After 30 minutes cells arestimulated with LPS 1 g/mL for 4 h. When studying CGS21680 , SCH58261, ZM24

8、1385, BAY60-6583, orGS6201, the adenosine receptor ligands are added 15 minutes before Apremilast. Methotrexate is added 24h and 1 h before Apremilast. Supernates are then collected and TNF- levels are quantified with the MouseTNF- Quantikine ELISA Kit. IC50 (EC50) calculations are made using non-li

10、aperitoneal injections of either MTX (1 mg/kg) or vehicle (PBS) for 4 weeks.Air pouches are generated by subcutaneous injection of 3 mL of sterile air and reinflated with 1.5 mL ofsterile air 2 days later. Vehicle (0.5 % carboxymethylcellulose and 0.25 % Tween 80) or Apremilast (5 mg/kg)are orally d

11、osed, with a syringe through a blunt-ended curved feeding tube, 24 h and 1 h before inflammationis induced on day 6 by injection of 1 mL of 2 % carrageenan suspension. Four hours later, mice are killed byCO2 narcosis, and exudates harvested with 2 mL PBS. Leukocytes are counted in a hemocytometer2/3

13、y available. Blood samples (0.3 mL) are collectedfrom the tail vein into heparinized 1.5 mL polythene tubes at 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8 and 12 h afteroral administration of Apremilast (6.0 mg/kg). The samples are immediately centrifuged at 4,000 g for 8 min.The plasma obtained (100 L)

14、is stored at 20C until analysis. Plasma Apremilast concentration versus timedata for each rat is analyzed by DAS (Drug and statistics) software.MCE has not independently confirmed the accuracy of these methods.
