Sea cucumber is a marine invertebrate that contains attractive bioactive secondary metabolites and these metabolites can be used for health as well as cosmetics. &lt;strong&gt;Objective:&lt;/strong&gt; The aim of the study was to determine the activity of tyrosinase inhibitors, antioxidants, and cytotoxicity of sea cucumber methanolic extract. &lt;strong&gt;Methods:&lt;/strong&gt; Dried sea cucumber samples were taken from Boalemo waters, Tomini Bay, Indonesia. Tyrosinase inhibitor assay was carried out spectrophotometrically using tyrosinase enzymes and L-DOPA as a substrate and antioxidant tests were carried out by DPPH method. Cytotoxicity test against human breast cancer cell line (T47D) was conducted using the MTT assay. &lt;strong&gt;Results:&lt;/strong&gt; The study showed that &lt;em&gt;Bohadschia vitiensis&lt;/em&gt; had the best tyrosinase inhibitor activity with IC&lt;sub&gt;50&lt;/sub&gt; value of 0.28 mg/ml. The DPPH free radical scavenging testing showed that all sea cucumbers had weak antioxidant activity. On the other hand, cytotoxicity assay revealed that several sea cucumbers had good cytotoxicity against T47D cells, where &lt;em&gt;Holothuria atra&lt;/em&gt; and &lt;em&gt;Bohadschia marmorata &lt;/em&gt;showed strong cytotoxicities with IC&lt;sub&gt;50&lt;/sub&gt; values of 23.0 and 28.1 ug/mL, respectively. &lt;strong&gt;Conclusion:&lt;/strong&gt; Based on the study, it can be concluded that the dried sea cucumber from the Tomini bay region, Indonesia, has the potential to be developed as a source of tyrosinase inhibitors and cytotoxic agents.&lt;/p&gt;

This polysaccharide commonly is extracted from marine brown seaweed. There is lack of information on the fucoidan extracted from tropical brown algae and its anti-cancer activity.&lt;strong&gt; Objectives:&lt;/strong&gt; The objectives of this study were to purify fucoidan from &lt;em&gt;Sargassum &lt;/em&gt;sp&lt;em&gt;., Turbinaria &lt;/em&gt;sp&lt;em&gt;.&lt;/em&gt; and &lt;em&gt;Padina &lt;/em&gt;sp., and to evaluate their cytotoxicity against breast cancer (MCF-7) and colon cancer cells (WiDr). &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Fucoidan extraction was conducted by using acid extraction method. Purified fucoidans were obtained by DEAE cellulose column chromatography and confirmed by HPLC and FT-IR spectrometry. The cytotoxicity was evaluated by using the MTT (3-[4,5-dimethylthiazol-2-yl] -2,5- diphenyltetrazolium bromide) assay. &lt;strong&gt;Results:&lt;/strong&gt; Fucoidan from &lt;em&gt;Sargassum&lt;/em&gt; sp. and &lt;em&gt;Turbinaria&lt;/em&gt; sp. showed low cytotoxicity with IC&lt;sub&gt;50&lt;/sub&gt; ranging between 461-663 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL. Higher cytotoxicity against MCF-7 and WiDr was showed by fucoidan from Padina sp. with IC&lt;sub&gt;50&lt;/sub&gt; of 144 and 118 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL, respectively. While its IC&lt;sub&gt;50&lt;/sub&gt; against Vero cells was 501 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL.Standard fucoidan from Fucus vesiculosus exhibited IC&lt;sub&gt;50&lt;/sub&gt; of 60, 63 and 211 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL against MCF-7, WiDr and Vero Cells, respectively. Although the IC&lt;sub&gt;50&lt;/sub&gt; was higher than that of standard fucoidan, &lt;em&gt;Padina&lt;/em&gt; sp. fucoidan showed cytotoxicity comparable with standard fucoidan at concentrations below 100 &lt;em&gt;&amp;mu;g&lt;/em&gt;/mL. &lt;b&gt;Conclusion:&lt;/b&gt; These results indicated that &lt;em&gt;Padina&lt;/em&gt; sp.fucoidan showed potential selective cytotoxicity, and promising for the development of an anti-cancer compound.&lt;/p&gt;
