Background Seaweeds are taxonomically diverse benthic algae, which are rich in bioactive compounds. VERO cell lines by MTT assay. Conclusions The methanolic extracts of seaweeds and possess high total phenolic content and shows a good free radical scavenging activity and hence are proven to have better antioxidant activity and they might be good candidates for further investigations in order to develop potential anticancer drugs. (red algae), (brown algae) and (green algae) depending on their nutrient and Cabazitaxel cost chemical composition. The growth of seaweeds favor in high light and oxygen concentration but in these conditions photo damaging and free radical production may result. Since the sea weeds possess anti-oxidative mechanism and compounds, they protect themselves from stress due to free radical formation and serious photodynamic damage (1). A number of factors influence the bioactive potential of seaweeds such as stage of fertility period, weather conditions and location. Cabazitaxel cost The crude extracts of most seaweeds show high bioactive potential during their fertility period (2). Antioxidants prevent oxidative processes by inhibiting the initiation or propagation of an oxidative chain reaction even when the amount of the antioxidant is less than the substance to be oxidized (3). During the last three decades the antioxidant-based drug formulations for the prevention and treatment of some oxidative stress related diseases have appeared. Reactive oxygen species can generate oxidative stress and play a role in the onset of nearly 150 pathophysiological disorders such as rheumatid arthritis, diabetes mellitus, inflammatory conditions, cancer, heart, genotoxicity diseases, early ageing (4). Several free radicals such as superoxide anion, hydrogen peroxide, nitric oxide, lipid peroxyl, singlet oxygen, lipid peroxide and hydroxyl radical, which are produced by all aerobic organisms and can easily react with most biological molecules including proteins, lipids, lipoproteins, and DNA have been reported in the literature (5). Therefore, algal species as alternative materials to extract natural antioxidative compounds have attracted much attention. There are epidemiological data supported by rodent model studies demonstrating protective effects of dietary kelps and other red and green algae against mammary, intestinal and skin carcinogenesis (6). Different methods have already been made to investigate the potential of organic antioxidants such as for example natural plant and chemical substances extracts. methods could be split into two main organizations: 1) hydrogen atom transfer reactions such as for example Oxygen Radical Absorbance Capability (ORAC), Total radical trapping antioxidant potential (Capture) and -carotene bleaching; 2) Electron transfer reactions like trolox comparable antioxidant capability (TEAC), Ferric lowering antioxidant power (FRAP), -diphenyl–picryl-hydrazyl radical scavenging assay (DPPH), superoxide anion radical scavenging assay, hydroxyl radical scavenging assay, nitric oxide radical scavenging Cabazitaxel cost assay and total phenol assay have already been reported in the books (7). These procedures have become delicate and well-known but to estimation antioxidant properties of vegetable components, it’s important to handle several method because the phytochemicals are complicated in character Rabbit polyclonal to ACN9 (8). Many analysts have reported for the antioxidant and antimicrobial activity of seaweeds (9). Nevertheless, reviews for the antimicrobial and antioxidant activity of seaweed components from Mahabalipuram, Tamilnadu, India have become limited. The bioactive properties such as for example antioxidant, antiproliferative and antimicrobial ramifications of 3 seaweeds were analyzed using different assays. 2. Goals The purpose of this scholarly research was to research the bioactive properties of 3 seaweed examples; and had been gathered from shorelines of Mahabalipuram, Tamilnadu. 3. Methods and Materials 3.1. Assortment of Seaweeds Three seaweed examples had been gathered along the Mahabalipuram shoreline, Tamil Nadu, and had been defined as and and had been from Microbial Type tradition collection & Gene Loan company, (MTCC) Chandigarh, India. Two tumor cell lines specifically MCF-7 (breasts cancer cell range) and HepG2 (Liver organ cancer cell range) and VERO (regular cell range) had been purchased through the National Center for Cell Technology (NCCS), Pune.
