Astaxanthin
Based on 19 publication(s) in Google Scholar
Astaxanthin, the red dietary carotenoid, is an orally effective and potent antioxidant. Astaxanthin inhibits NF-κB and down-regulates VEGF in blood glucose. Astaxanthin exerts anti-cancer cell proliferation, increases apoptosis, impairs migration and invasion by activating PPARγ and reducing the expression of STAT3. Astaxanthin also has neuroprotective and anti-inflammatory activity and can be used in studies of cancer, diabetic retinopathy, cardiovascular disease, and in the coloring of animal feed.

Astaxanthin (50, 100, 150, 200 μM; 48 h) inhibits the proliferation of DU145 cells (IC50<200 μM)[1].
Astaxanthin (200 μM; 24 h) reduces the expression of STAT3 and the related pathway proteins (at both protein and mRNA levels) by inhibiting proliferation, increasing apoptosis and weakening migration and invasion[1]
Astaxanthin protects RPE cells from abnormal activation and oxidative stress (induced by high glucose) by down-regulating VEGF in high glucose at protein levels[2].
Astaxanthin (1-50 μM; 72 h) upregulates protein expression of PPARγ in time- and dose-dependent manners in K562 cells[3].

Typical DHE fluorescence in zebrafish larvae exposed to PFOS and treated with vitamin C, vitamin E, and Astaxanthin. The results showed that Astaxanthin (AX, 1% w/w in fodder; 0.1 mg/larva/day and 10 mg/adult/day for 4 weeks), when supplemented to the fodder as an antioxidant, scavenged the overload of superoxide induced by PFOS in the liver.
Astaxanthin purchased from MedChemExpress. Usage Cited in: J Hazard Mater. 2025 Dec 8:501:140750. [Abstract]
Panels show typical images of hyperemia and Alcian blue–Alizarin red staining in the zebrafish anal fin, respectively. The zebrafish were exposed to 3 μM PFOS for two weeks. Astaxanthin or vitamin E was incorporated into the fodder during the second week of PFOS exposure. Black arrows indicate areas of hyperemia. The results showed that Astaxanthin (AX, 1% w/w in fodder; 0.1 mg/larva/day and 10 mg/adult/day for 4 weeks) significantly reversed the hyperemia around the anal fin joints and narrowed intraarticular space induced by PFOS.

Representative images of mouse pancreatic tissues collected from the control, AP, and AP + Astaxanthin (ATX) groups (stained with H&E), and their pathology scores. H&E staining revealed that activation of Nrf2 by Astaxanthin (ATX, 40 mg/kg; single dose) significantly alleviated edema and inflammatory cell infiltration in mouse pancreatic tissue, and also markedly reduced the pathological scores of the pancreas.
