Abstract

The objectives of this research were to assess cytotoxic activity and examine characteristic of sea cucumber Actinopyga sp. methanolic extract. Cytotoxicity assay was conducted using MTT method against WiDr (colon cancer) and T47D (breast cancer) cell lines. Actinopyga sp. methanolic extract was characterized by using phytochemical screening, Transform-Infrared (FT-IR) spectroscopy, dan  Liquid Chromatography Ion Trap Time of Flight Mass Spectrophotometer (LC-IT-ToF-MS).  The result showed that Actinopyga sp. methanolic extract inhibited Widr and T47D cell lines viability with the IC50 value of 55.93 and 87.55 µg/mL, respectively. Functional groups analysis showed the presence of hydroxyl, amine, carboxylic acid, nitrate, amide, sulphur, ester, and ether. LC-IT-ToF-MS analysis of crude extract showed that it containing many steroids compound.

Abstract

Spons merupakan hewan multiseluler yang paling sederhana sekaligus merupakan sumber senyawa bioaktif yang sangat berguna di dalam bidang farmasi. Senyawa-senyawa baru yang sangat beragam sudah banyak yang diisolasi dari spons. Kesulitan utama dalam memproduksi senyawa obat baru dari spons adalah kurang mencukupinya jumlah senyawa bioaktif yang dihasilkan spons untuk keperluan uji preklinis dan klinis karena rendemen yang dihasilkan sangat rendah. Artikel ini merupakan tinjauan terhadap metode kultur sel spons untuk memproduksi senyawa bioaktif  dalam rangka mengatasi masalah suplai senyawa bioaktif yang diuji.  Produksi senyawa avarol dari kultur primmorph spons Dysidea avara dibahas dalam review ini.  Avarol dilaporkan  memiliki bioaktivitas yang kuat sebagai substansi antitumor, antibakteri, dan antivirus. Model pendekatan melalui kultur primmorph dapat digunakan sebagai cara yang menjanjikan  untuk memproduksi senyawa bioaktif dari spons.

Abstract

Sea cucumbers are one of Indonesia’s marine organism with the potential to be developed as possible herbal medicines. In a preliminary study of cytotoxic activity of ethanol extracts of 14Indonesian sea cucumber species, the most active extract came from the Holothuria sp. Thecurrent research aimed to identify the major cytotoxic component in the sea cucumber Holothuriasp., that yielded the most active extract. The samples were collected from South Lampung beach.Isolation of the cytotoxic component was done employing liquid flash and preparative reversedphase (C 18) chromatography. Cytotoxic ity evalu atio n of fractio ns collected durin g thechromatography was conducted using the MCF-7 tumor cell line. Elucidation of the structure ofmost active isolate was done by NMR (Nuclear Magnetic Resonance) spectroscopy and GC-FID(Gas-Chromatography-Flame Ionisation Detector) analysis. The results of these analyses showedthe most active compound to be stearic acid; IC 50towards MCF-7 cells 10.32 ppm.

Abstract

Marine algae contains bioactive secondary metabolites that  have potential to be developed as antioxidant. The aims of  this research were to investigate antioxidant activity and total phenolic compound of marine algae collected from Binuangeun Beach, Banten and to characterize antioxidant compounds from selected algae species. Antioxidant activity was determined by 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) assay and Ferric Ion Reducing Antioxidant Power (FRAP) Assay, while total phenolic content was estimated by Folin-Ciocalteau method. Isolation of bioactive antioxidant compound was performed using SiO2 column chromatography and preparative high performance liquid chromatography (HPLC). The antioxidan activity evaluation was conducted to methanol extracts  from 20 species (7 Chlorophyta, 9 Phaeophyta and 4 Rhodophyta). Results showed that Padina australis extract was found to be the most active. The major bioactive antioxidant compound was identified as fucoxanthin and a polar compound that was suspected as phenolic compound. The extracts of P. australis presented the highest phenolic content (58.59 mg GAE/g). A significant correlation between antioxidant capacity and total phenolic content was found, indicating that phenolic compounds are the major contributors to the antioxidant properties of P. australis.

Abstract

This research was aimed to isolate marine derived-fungi which associated with macro algae and sponge from Indrayanti Beach, Jogjakarta and to screen the antitumor (T47D and HeLa) bioactivity of the fungi extracts. Three solid media of MEA (malt extract agar), GPY (glucose peptone yeast) and MFM (minimal fungi medium) were used as isolation medium. Each of the pure fungi isolates was then cultivated in 100 ml of liquid medium for 4 weeks at room temperature (27-28°C) in static conditions. The antitumor activity of the fungi extracts were tested against breast tumor cells (T47D) and cervical cancer cells (HeLa) using Thiazolyl Blue Tetrazolium Blue (MTT) assay method. A number of 21 isolates of fungi were isolated from 4 macro algae and 1 sponge samples. The identification of fungi isolate was conducted using combination of molecular approach (ITS1-5.8S-ITS4 DNA regions) and macro-micro morphological characteristics. Among those 21 marine fungi species isolated, MFGK-21 extract showed the best anti-servical tumor (HeLa) with an IC50 value of 240.1 µg/ml and MFGK-27 extract showed the best anti-breast tumor (T47D) with an IC50 value of 59.6 µg/ml. The MFGK-21 fungi isolate was identified as Penicillium steckii, while the MFGK-27 fungi isolate was identified as Aspergillus sydowii.
