Nobiletin

Nobiletin is a poly-methoxylated flavone from the citrus peel that improves memory loss. Nobiletin is a retinoid acid receptor-related orphan receptors (RORs) agonist. Nobiletin can reduce reactive oxygen species (ROS) levels in differentiated C2C12 myotubes and has anti-inflammation and anti-cancer properties, including anti-angiogenesis, anti-proliferation, anti-metastasis and induced apoptosis^[1][2][3][4]. IC50 & Target:Retinoid acid receptor-related orphan receptors (RORs)^[1]; reactive oxygen species (ROS)^[1]; apoptosis^[2] In Vitro: Nobiletin (0-100 μM; 24 hours; U2OS and HOS cells) treatment progressively reduces protein expressions of MMP-2 and MMP-9. In U2OS and HOS cells, Nobiletin considerably reduces the phosphorylation of p-IKKα/β and p-IκBα, and protein expression of NF-κB in the cell nuclear fraction with the concomitant increase of the NF-κB expression in the cytosolic fraction. Nobiletin down-regulates the p-CREB and the SP-1 expressions in the nuclear fraction, whereas Nobiletin does not affect c-Jun and c-Fos expressions^[1].
Nobiletin (0-100 μM; 24 hours; U2OS and HOS cells) treatment significantly reduces mRNA expressions of MMP-2 and MMP-9 dose-dependently in U2OS and HOS cells^[1]. In Vivo: Nobiletin (0.1% of regular diet; oral administration; daily; for 20 weeks; male C57BL/6 mice) treatment restores glucose homeostasis and promots energy expenditure and circadian activity in aged mice^[2].
