The secondary purposes of this study are to assess the pharmacodynamic effects of single, oral doses of SRT2104 (250 mg, 500 mg, 1000 mg, 2000 mg) and prednisolone (30mg) as measured by levels of IL-6, IL-8 and IL-1beta in whole blood of healthy adult subjects. In addition, plasma pharmacokinetics, safety and tolerability of SRT2104 following the administration of single, oral doses of SRT2104 (250 mg, 500 mg, 1000 mg, 2000 mg) in healthy adult subjects will also be assessed. As exploratory endpoints, transcriptomic profiles, biomarker exploration, and relationships between plasma SRT2104 levels and ex vivo LPS-induced TNF-alpha production may also be examined.
