Zeaxanthin dipalmitate (Physalien) is a lutein carotenoid found in fruits with anti-inflammatory, hepatoprotective, and anti-oxidative stress activity that attenuates ethanol-induced liver injury.Zeaxanthin dipalmitate restores mitochondrial autophagy, a function that has been inhibited by ethanol intoxication. Zeaxanthin dipalmitate protects degenerated photoreceptors in the retina of mice and improves visual acuity in a mouse model of photoreceptor degeneration, and may be used in studies of alcoholic fatty liver disease (AFLD) and retinitis pigmentosa (RP).

In vitro | Zeaxanthin dipalmitate directly interacted with P2X7 receptor (Kd=81.2 nM) and lipocalin receptor 1 (AdipoR1; Kd=533 nM) in a positive dose-dependent manner. Zeaxanthin dipalmitate (1 µM; 2 h) was able to completely or partially reverse the down-regulation of Atg5, beclin-1, and LC3A/B by ethanol (250 mM) in BRL-3A cells, as well as up-regulation of p62 by ethanol, and partially restored ethanol-suppressed LC3B expression in BRL-3A cells. It also partially restored the viability and ethanol-induced caspase-3/7 activity of ethanol-inhibited BRL-3A cells, and restored the ethanol-induced inhibition of mitochondrial autophagy in BRL-3A cells.

In vivo | Zeaxanthin dipalmitate (10 mg/kg orally once daily for two weeks) effectively reduced serum ALT and AST levels due to prolonged ethanol challenge in an AFLD model. In addition, this dose of Zeaxanthin dipalmitate was able to significantly attenuate tissue damage and slow down the extent of hepatocyte apoptosis (as assessed by caspase-3/7 activity) and inflammation (TNF-alpha) due to AFLD. In rd10 mice, a single intravitreal injection of Zeaxanthin dipalmitate (~4 μM) was able to improve their visual behavior and delay the degeneration of retinal photoreceptors. Also, this dose enhanced the light response of photoreceptors, bipolar cells, and retinal ganglion cells, and reduced the expression of genes associated with inflammation, apoptosis, and oxidative stress in rd10 mice.
