Fucoxanthin Ameliorates Oxidative Stress and Airway Inflammation in Tracheal Epithelial Cells and Asthmatic Mice.
    Cells, 2021, 05-25, Volume: 10, Issue:6

    Fucoxanthin is isolated from brown algae and was previously reported to have multiple pharmacological effects, including anti-tumor and anti-obesity effects in mice. Fucoxanthin also decreases the levels of inflammatory cytokines in the bronchoalveolar lavage fluid (BALF) of asthmatic mice. The purpose of the present study was to investigate the effects of fucoxanthin on the oxidative and inflammatory responses in inflammatory human tracheal epithelial BEAS-2B cells and attenuated airway hyperresponsiveness (AHR), airway inflammation, and oxidative stress in asthmatic mice. Fucoxanthin significantly decreased monocyte cell adherence to BEAS-2B cells. In addition, fucoxanthin inhibited the production of pro-inflammatory cytokines, eotaxin, and reactive oxygen species in BEAS-2B cells. Ovalbumin (OVA)-sensitized mice were treated by intraperitoneal injections of fucoxanthin (10 mg/kg or 30 mg/kg), which significantly alleviated AHR, goblet cell hyperplasia and eosinophil infiltration in the lungs, and decreased Th2 cytokine production in the BALF. Furthermore, fucoxanthin significantly increased glutathione and superoxide dismutase levels and reduced malondialdehyde (MDA) levels in the lungs of asthmatic mice. These data demonstrate that fucoxanthin attenuates inflammation and oxidative stress in inflammatory tracheal epithelial cells and improves the pathological changes related to asthma in mice. Thus, fucoxanthin has therapeutic potential for improving asthma.

Assessment of the Therapeutic Effects of Fucoxanthin by Attenuating Inflammation in Ovalbumin-Induced Asthma in an Experimental Animal Model.
    Journal of environmental pathology, toxicology and oncology : official organ of the International Society for Environmental Toxicology and Cancer, 2019, Volume: 38, Issue:3

    Asthma has affected more than 300 million people worldwide and is considered one of the most debilitating global public health problems based on a recent statistical report from the Global Initiative for Asthma. Inflammation of the airways leads to the various interrelated mechanisms of innate and adaptive immunity acting mutually with the epithelium of the respiratory organ. Fucoxanthin is an orange or brown pigment which is naturally found in various seaweeds. To the best of our knowledge, there are no scientific claims or evidence of the curative effects of fucoxanthin against asthma. Hence, this present research was designed to investigate the curative activity of fucoxanthin against ovalbumin-induced asthma in a mouse model. Fucoxanthin (50 mg/kg) showed significant (P < 0.001) antiasthma activity. It effectively decreased intracellular secretion of reactive oxygen species and increased antioxidant enzyme activity. Fucoxanthin also decreased inflammatory cytokine markers in bronchoalveolar lavage fluid. Because fucoxanthin showed effective antiasthma activity against ovalbumin-induced asthma in experimental animals, further research on this natural antioxidant could lead to development of a novel drug for the treatment of asthma in humans.
