Purity: ≥98%
Canthaxanthin (E 161g; all-trans-Canthaxanthin) is a trans-carotenoid pigment and a red-orange carotenoid with various biological activities, such as antioxidant, antitumor properties. The compound is used as an orally bioavailable suntanning agent and as a food and drug coloring agent. orally bioavailable ingestion of the compound causes canthaxanthin retinopathy.
| ln Vitro |
Enriching LDL with canthaxanthin may be able to prevent cholesterol from oxidizing. Apart from its ability to scavenge and act as an antioxidant (e.g., by inducing catalase and superoxide dismutase), canthaxanthin also possesses immunomodulatory properties (e.g., by promoting the proliferation and function of cells in an immunocompetent state) and regulates, which is crucial for communication (e.g., by inducing transmembrane proteins connexin) [1]. The total number of tumor cells is dramatically reduced by canthaxanthin at doses ranging from 0.1 to 1 × 1000 μM. After 72 and 96 hours of isolation, maximum inhibition was seen at a canthaxanthin concentration of 1000 [2].

| ln Vivo |
Canthaxanthin alters the ability of tissues to protect against oxidative stress. After 15 days of canthaxanthin treatment at a dose of 14 μg/kg, carotenoids were added annually to HW, reaching a content of 0.52 ± 0.05 nmol/g. Mice treated with canthaxanthin showed a 35% decrease in glutathione peroxidase activity compared to Manhattan, and a 28% decrease in catalase (59%) and mango superoxide dismutase (28%) activities compared to the dye solution [3]. The dosage of supplements has an impact on both the growth of breast tumors and their anti-tumor activity [4]. Breast cancer incidence is reduced by 65% when canthaxanthin is added to the diet three weeks prior to admission, through a mechanism unrelated to provitamin A activity [5].

| Additional Infomation |
Canthaxanthin is a carotenone that consists of beta,beta-carotene bearing two oxo substituents at positions 4 and 4'. It has a role as a biological pigment, a food colouring, a fungal metabolite and an Escherichia coli metabolite. It derives from a hydride of a beta-carotene.
Canthaxanthin has been reported in Planktothrix rubescens, Planktothrix agardhii, and other organisms with data available. A trans-carotenoid pigment widely distributed in nature. The compound is used as an oral suntanning agent and as a food and drug coloring agent. Oral ingestion of the compound causes canthaxanthin retinopathy. |
