All-trans-retinal (Vitamin A aldehyde) is a one of the major vitamin A metabolites in the retina. All-trans-RAL is regenerated to the visual chromophore, 11-cis-retinal in physiological conditions.

9-cis-Retinal is a retinoid with Kd of 8 nM and 5 nM for cellular retinol binding protein-I (CRBP-1) and CRBP-II, respectively. 9-cis-Retinal accelerates the differentiation and maturation of rod photoreceptors in retinal organoids, reduces the toxicity of unliganded opsins, and can be used to study congenital stationary night blindness caused by G90D rhodopsin.

Docosahexaenoic Acid (DHA) is an essential omega-3 fatty acid prevalent in the brain and retina.

Retinol (Alphalin) and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of CAROTENOIDS found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products.

Timosaponin BII (Prototimosaponin A III) exhibits anti-dementia and antioxidant activities, with potential applications in treating type 2 diabetes. It can inhibit the up-regulation of BACE1 and reduce the over-production of β-CTF and Aβ in rat retina induced by FeCl.

Phosphatidylserine is a naturally occurring phospholipid that comprises 2-10% of total phospholipids in mammals and is enriched in the central nervous system, particularly the retina. It is anionic and found mainly on the inner leaflet of the cell membrane. It is biosynthesized from phosphatidylcholine or phosphatidylethanolamine by phosphatidyl synthase 1 (PSS1) or PSS2, respectively, in the endoplasmic reticulum and can be reversibly converted back by the same enzymes. It can also be irreversibly converted to phosphatidylethanolamine by phosphatidylserine decarboxylase in the mitochondria. Phosphatidylserine binds to T cell immunoglobulin mucin type 1 (TIM-1) and TIM-4 receptors as well as brain-specific angiogenesis inhibitor 1 (BAI1), leading to anti-inflammatory and anti-atherosclerotic effects. It is also a cofactor involved in the activation of various signaling pathways through activation of protein kinase C, neutral sphingomyelinase, and c-Raf-1 protein kinase among others. Phosphatidylserine is externalized during apoptosis by scramblases in the plasma membrane as a signal for phagocytes to engulf the cell. Phosphatidylserines (bovine) is a mixture of bovine phosphatidylserines containing fatty acids with variable chain lengths at the sn-1 and sn-2 positions.

1. Obtusifolin has antioxidant properties and improves chemically induced diabetes and its complications by modulation of oxidative stress. 2. Obtusifolin suppresses phthalate esters-mediated bone resorption, thus may be a novel anti-breast-cancer bone me

Zeaxanthin is a dietary carotenoid that accumulates in the retina (particularly the macula) and has antioxidant activity that may improve obesity, prevent age-related macular degeneration, and protect against nonalcoholic steatohepatitis.

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).
