Apremilast (CC-10004)

InformationApremilast (CC-10004) is a potent and orally activePDE4andTNF-αinhibitor withIC50of 74 nM and 77 nM, respectively.In vitroApremilast is more potent for inhibition of PDE4 compared with cAMP or cGMP hydrolysing enzymes from other PDE families. Apremilast displays a broad pattern of anti-inflammatory activity in a variety of cell types, inhibits TNF-α, IL-12 and IL-23 production, as well as NK and keratinocyte responses. Apremilast is found to inhibit the zymosan-induced PMN production of IL-8 with IC50 of 94 nM. Apremilast inhibits fMLF-induced PMN CD18 and CD11b expression with IC50 of 390 nM and 74 nM, respectively, and inhibits fMLF-induced adhesion of PMN to HUVECs with IC50 of 150 nM. Apremilast inhibits keratinocyte TNF-αproduction, with no effect on keratinocyte cell viability as measured by intracellular ATP levels. .In vivoApremilast is stable in the presence of human microsomes (t1/2 > 60 min). It is 90% protein bound in human plasma. Oral and intravenous administration of it in female rats showed that it have good pharmacokinetics with low clearance, a moderate volume of distribution, and a 64% oral bioavailability. In a LPS-induced TNF-αinhibition model in rats, examined the TNF-α inhibitory ability of Apremilast in vivo, and the ED50 is determined to be 0.03 mg/kg. In another LPS-induced neutrophilia model in rats, Apremilast exhibited an ED50 range from 0.3 mg/kg to 0.9 mg/kg.Cell Datacell lines：59 cancer cell linesConcentrations：~10 μMIncubation Time：18 hPowder Purity:≥99%.
