Astaxanthin is a naturally occurring red dietary carotenoid isolated from Haematococcus pluvialis and a keto-carotenoid that belongs to a larger class of chemical compounds known as terpenes (as a tetraterpenoid) built from five carbon precursors, isopentenyl diphosphate, and dimethylallyl diphosphate. Astaxanthin has potential in the treatment of various diseases, such as cancers and Parkinson’s disease, cardiovascular disease. Due to its bright red colour, Astaxanthin could be used as a food colorant in animal feeds. It is a red dietary carotenoid isolated from Haematococcus pluvialis and is an inhibitor of PPARγ with potent antiproliferative, neuroprotective and anti-inflammatory activity.
ln Vitro |
DU145 cell growth is inhibited by astaxanthin (50, 100, 150, and 200 µM; 48 hours) (IC50<200 µM) [1]. By preventing proliferation, promoting apoptosis, and hindering migration and invasion, astaxanthin (200 µM; 24 hours) lowers the expression of STAT3 and related pathway proteins (at the protein and mRNA levels) [1]. Additionally, astaxanthin shields RPE cells from oxidative stress and abnormal activation brought on by high glucose by downregulating VEGF at the protein level [2]. In K562 cells, astaxanthin (1-50 µM; 72 hours) increases the expression of the PPARγ protein in a dose- and time-dependent way [3].

ln Vivo |
In mice that are not clothed, astaxanthin (200 mg/kg; gavaged once daily for three weeks) prevents the formation of tumor xenografts (DU145) [1]. In rats, astaxanthin (125 or 500 mg/kg; in animal feed; 7 days) significantly lowers oxidative stress and offers cardioprotection [4].

Cell Assay |
Apoptosis analysis [1]
Cell Types: DU145 Cell Tested Concentrations: 200 µM (pre-incubation) Incubation Duration: 24 hrs (hours) Experimental Results: The percentage of apoptotic cells increased from 8.5% to 13.1% (compared to blank control). Cell migration assay[1] Cell Types: DU145 Cell Tested Concentrations: 200 µM Incubation Duration: 24 hrs (hours) Experimental Results: DU145 cells demonstrated diminished migration and invasion (approximately 41% of cells could not move from one chamber to another, 36% of cells could did not pass through the Transwell membrane compared to the control group). Cell proliferation assay[2] Cell Types: ARPE-19 Cell Tested Concentrations: 50 µM (pre-incubation) Incubation Duration: 7 days Experimental Results: Cell proliferation was Dramatically diminished when exposed to high glucose. Western Blot Analysis[1] Cell Types: DU145 Cell Tested Concentrations: 200 µM Incubation Duration: 24 h Experimental Results: The expression of STAT3 was diminished at both the protein and mRNA levels (down-regulated the protein expression of JAK2, BCL-2 and NF-κB, up-regulated BAX , protein express |
Animal Protocol |
Animal/Disease Models: Nude mouse (approximately 20 grams; DU145 tumor xenograft model) [1].
Doses: 200 mg/kg Route of Administration: intragastric (po) (po)administration; one time/day for 3 weeks. Experimental Results: It has a significant inhibitory effect on tumor growth. Animal/Disease Models: Female C57BL/6 mice (7 weeks old) [4]. Doses: 125 or 500 mg/kg Route of Administration: Animal feed; 7 days. Experimental Results: The mean infarct size was Dramatically diminished to 45.1% and 39.1% in the two treatment groups (125 and 500 mg/kg), respectively. The myocardial salvage rates in the 125 mg/kg group and 500 mg/kg group were 26% and 36%, respectively. 9-HETE levels were Dramatically diminished in a dose-dependent manner. 9-HETE is a regioisomer oxidation product of arachidonic acid and is thought to be a product of free radical-mediated oxidation. |
