This study investigated the use of polyglyceryl esters (PGE) as stabilizer in improving stability and anti-inflammatory activity of nanosuspended branched-chain amino acids (BCAAs). BCAAs nanosuspended with stabilizer (BS) exhibited improved stability at concentration of 5% saturation level during storage as compared to BCAAs nanosuspended with aqueous solution (BA). Additionally, anti-inflammatory activity of BS was found to be greater than that of BA. Nitric oxide scavenging activity was found to be dose-dependent, with activity of BS in sodium nitroprusside system being significantly higher than that of BA (p < 0.05) at 2.5–20 mg/mL. BS also possesses greater inhibitory activity on production of pro-inflammatory factors including inducible nitric oxide synthase, cyclooxygenase-2 (COX-2), interleukin-1β (IL-1β), interleukin-6 (IL-6) in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells through suppressed phosphorylation of p65 subunit of NF-κB at 0.5, 2, 8 mg/mL. These results suggest that PGE used as stabilizer improves solubility and biological activity of nanosuspended BCAAs.
