Antioxidant and antitumoural activities of some Phaeophyta from Brittany coasts

Anticancer and Antioxidant Activities of Some Algae from Western Libyan Coast

“…Under the same experimental conditions, the extracts were additionally tested using Human Corneal Epithelial Cells (HCEC) cell lines in order to examine their cytotoxic effect on normal cells ( Figure 3). Figure 2B); this was in agreement with observations of previous study [9].…”

“…Also seaweeds are considered as a source of bioactive compounds as they are able to produce a great variety of secondary metabolites, characterized by a wide range of biological activities such as antimicrobial [2][3][4], anti-inflammatory [5], anti-viral; as well as anti-tumoral activities [7,8]. Moreover, many studies show that some algal extracts display substantial antioxidant activities [9][10][11][12].…”

Biological potential of marine macroalgae of the genusCystoseira

“…Similar to us, Stanojković et al [27] demonstrated that C. amentacea extract had cytotoxic effects in various human cell lines (human breast cancer, human cervix adenocarcinoma, human colon carcinoma). As shown in a recent work Zubia et al [30], Cystoseira species possess, among their more significant compounds, different types of terpenes as the bioactive compounds. These terpene compounds could be responsible for the cytotoxic activities of the Cystoseira extracts.…”

“…Cystoseira species extracts were also screened for their cytotoxic activity by other researchers against different cell lines. For instance, C. tamariscifolia extract exhibited strong cytotoxic activity against Daudi, Jurkat and K562 tumor cell lines [30]. The hexane fraction of the methanolic extract from C. myrica (S.G.Gmelin) C. Agardh showed an interesting activity against T47D (breast carcinoma) (IC 50 = 99.9 μg/mL) and mainly against MDA-MB468 (breast carcinoma estrogen receptor independent (IC 50 = 56.5 μg/mL) [11].…”

Macroalgae of Izmir Gulf: Dictyotaceae exhibit high in vitro anti-cancer activity independent from their antioxidant capabilities

“…Macroalgae are prolific sources for numerous natural compounds with promising potential for both prevention (Lee et al 2013) and treatment of several diseases including cancer (Hiroishi et al 2001;RademakerLakhai et al 2005) and diabetes (Nwosu et al 2011). Many studies have attributed beneficial effects of macroalgae to their high antioxidant capacity (Zhang et al 2007;Zubia et al 2009;Murugan and Iyer 2013) thus naming their consumption ''antioxidant phytomedicine'' (Scalbert et al 2005;Yuan and Walsh 2006;Gupta and Abu-Ghannam 2011;Nwosu et al 2011). Dietary antioxidant intake and decreased oxidative stress are known to reduce the risk of type II diabetes (Valko et al 2004) and cancer (Montonen et al 2004) as both conditions are associated with oxidative stress.…”
