Abstract
Nanofibers for drug delivery systems have gained much attention during the past years. This paper describes for the first time the loading of a bioactive precipitate (JAD) from the marine sponge Jaspis diastra in PDX and fucoidan-PDX. JAD was characterized by LC-MS/MS and the major component was jaspamide (1) with a purity of 62.66 %. The cytotoxicity of JAD was compared with paclitaxel (PTX). JAD and PTX displayed IC50 values of 1.10 ± 0.7 μg/mL and 0.21 ± 0.12 μg/mL on skin fibroblasts L929 cells whilst their IC50 values on uveal MP41 cancer cells, were 2.10 ± 0.55 μg/mL and 1.38 ± 0.68 μg/mL, respectively. JAD was found to be less cytotoxic to healthy fibroblasts compared to PTX. JAD and PTX loaded scaffolds showed sustained release over 96 h in physiological medium which is likely to reduce the secondary cytotoxic effect induced by JAD and PTX alone. The physico-chemical properties of the loaded and unloaded scaffolds together with their degradation and action on tumor microenvironment by using L929 and MP41 cells were investigated. JAD and PTX at a concentration of 0.5 % (drug/polymer, w/w) in the electrospun mats prevented growth and proliferation of L929 and MP41 cells. Co-culture of L929 and MP41 showed that the JAD and PTX loaded mats inhibited the growth of both cells and caused cell death.

Abstract
Tropical lagoon-inhabiting organisms live in highly irradiated ecosystems and are particularly susceptible to thermal stress resulting from climate change. However, despite living close to their thermal maxima, stress response mechanisms found in these organisms are poorly understood. We used a novel physiological-proteomic approach for sponges to describe the stress response mechanisms of the lagoon-inhabiting sponge Amphimedon navalis, when exposed to elevated seawater temperatures of +2°C and +4°C relative to a 26°C ambient temperature for 4 weeks. After 4 weeks of thermal exposure, the buoyant weight of the sponge experienced a significant decline, while its pumping rates and oxygen consumption rates significantly increased. Proteome dynamics revealed 50 differentially abundant proteins in sponges exposed to elevated temperature, suggesting that shifts in the sponge proteome were potential drivers of physiological dysfunction. Thermal stress promoted an increase in detoxification proteins, such as catalase, suggesting that an excess of reactive oxygen species in sponge cells was responsible for the significant increase in oxygen consumption. Elevated temperature also disrupted cellular growth and cell proliferation, promoting the loss of sponge biomass, and the high abundance of multiple α-tubulin chain proteins also indicated an increase in cytoskeletal activities within sponge cells, which may have induced the increase in sponge pumping rate. Our results show that sustained thermal exposure in susceptible lagoonal sponges may induce significant disruption of cellular homeostasis, leading to physiological dysfunction, and that a combined physiological-proteomic approach may provide new insights into physiological functions and cellular processes occurring in sponges.

Abstract
Molecular properties and biological functions of Pyrenaican SF-1 as a novel biological macromolecule extracted from a fungal isolate were studied. The isolate was identified as Daldinia pyrenaica on the basis of 5.8S rDNA sequencing. Pyrenaican SF-1 was obtained from the culture filtrate of the fungal isolate. The partial characterization of biochemical structure of Pyrenaican SF-1 was conducted. The fungal extract was also tested for the treatment of AGS, MDA and HeLa cell lines to assess cells proliferation, cells cycle and apoptosis. Furthermore, Pyrenaican SF-1 extract was tested for its antibacterial and antioxidant activity. Initial chemical analysis revealed that Pyrenaican SF-1 extract was composed of various monosaccharides such as d-glucose, D- mannitol, D-arabinose and β-D-ribopyranose. In vitro study indicated that Pyrenaican SF-1 could effectively elevate percentage of apoptosis and necrosis of cancer cells and block cell cycle phase of the control group. The fungal extract could inhibit proliferation of Hela and MDA cell up to 67% and 56%, respectively. Moreover, Pyrenaican SF-1 represented a strong antioxidant activity compared to that one obtained from vitamin C. On the other hand, Pyrenaican SF-1 exhibited growth inhibitory effects against different Gram-negative and Gram-positive bacterial strains. Pyrenaican SF-1 can be considered as a bioactive macromolecule with promising application in pharmaceutical and medical sectors.

Abstract
This study aimed to evaluate the in vitro activity of extracts of two marine sponge species, occurring in the shallows of the Yucatan peninsula coast, on two cancer and one normal mammalian cell lines. Hexane, dichloromethane, ethyl acetate and methanol extracts of Halichondria magniconulosa and Halichondria melanadocia were screened for their cytotoxic activity against hormone-dependent breast cancer (MCF-7) and human cervix cancer (SiHa) cell lines. The ethyl acetate extract of H. magniconulosa exhibited significant cytotoxicity against MCF-7 cells to a CC50 of 0.8 µg/mL, as well as high selectivity (SI = 24.5). On the other hand, SiHa cells were moderately sensitive to the dichloromethane and ethyl acetate extracts of the same species. (CC50 = 34.9 and 31.5 µg/mL, respectively). None of the extracts of H. melanadocia were considered active due their CC50's were ranged from 59.0 to 94.5 µg/mL.

Abstract
Background:
Aromatic amino acid-based surfactants have been found to have interesting
biological properties such as antibacterial and hemolytic activities. Recently, we have reported the antibacterial
activity of a range of ester hydrochloride surfactants derived from L-Phenylalanine and LTyrosine.
This study aims at assessing the antioxidant, α-glycosidase inhibitory and cytotoxic activities
of a series of L-Phenylalanine and L-Tyrosine ester hydrochlorides. Molecular docking and BSA binding
studies were also carried out in order to investigate their potential therapeutic targets.
Methods:
L-Phenylalanine and L-Tyrosine surfactants were tested as potential lipophilic antioxidants
using the DPPH and ABTS assays. These surfactants were also tested for their α-glycosidase inhibitory
activity using 4-nitrophenyl α -D-glucopyranoside (pNPG) as substrate. Their cytotoxicity effects were
screened using HeLa and KB cell lines. Glide version 5.7 as implemented in Schrödinger suite 2013-1,
was used for performing docking studies of L-Phenylalanine and L-Tyrosine dodecyl esters. The interaction
of the ester hydrochlorides of L-Phenylalanine and L-Tyrosine with bovine serum albumin (BSA)
was investigated using fluorometric titration.
Results:
The presence of the phenolic moiety in L-Tyrosine-based surfactants was found to enhance the
antioxidant and α-glucosidase inhibitory activities compared to the L-Phenylalanine derivatives. The α-
glucosidase and anticancer activities of the phenylalanine surfactants were found to increase with chain
length up to C12 above which the activities exhibited a downward trend. In the case of the tyrosine series,
an increase in chain length from C8 to C14 was found to decrease the α-glucosidase inhibitory
activity and increase the anticancer activity of the surfactants. Binding studies with bovine serum albumin
showed that the tyrosine surfactants displayed greater affinity for the serum albumin, owing to the
presence of the phenolic group which altered the orientation of the surfactant molecule within the hydrophobic
core of BSA.
Conclusion:
L-Tyrosine esters having a phenolic moiety were found to possess enhanced biological
activity in terms of both the antioxidant and antidiabetic activities as well as also bind more strongly to
Bovine serum albumin. Molecular docking studies of the phenylalanine and tyrosine surfactants of similar
chain length with target proteins showed direct correlation with their anticancer and antidiabetic
activity. Therefore, the findings show that these aromatic based surfactants derived from L-Tyrosine can
act as promising antioxidant, antidiabetic and anticancer agents, and they can also be efficiently transported
and eliminated in the body, making them useful candidates for drug designs.

Abstract
Background: Breast cancer is the second leading cause of death in women. Alternative medicine with high efficacy is needed for breast cancer treatments, for example induction of apoptosis using natural products. It has been found that many natural apoptosis-inducing compounds are isolated from marine sponge. The objective of this study is to analyze the ability of extracts of the sponge Ancorina sp. to induce apoptosis on human breast cancer T47D cell line and find out its mechanism. Methods: T47D cells were treated with crude extracts of methanol, dichloromethane:methanol (1:1) and dichloromethane Ancorina sp. for 24 h, and doxorubicin was used as a positive control. Methods used for this study were MTT assay to examine cell viability and determine IC 50 of the three extracts, while the percentage of apoptosis and caspase-3 were investigated by flow cytometry. Results: IC 50 values of methanol, dichloromethane:methanol (1:1), and dichloromethane extract were 84.25, 121.45, and 99.85μg/mL respectively. The percentages of apoptotic cells after treatment with methanol, dichloromethane:methanol (1:1), and dichloromethane extracts were 88.68, 27.54 and 53.63% respectively, whereas the percentage of caspase-3 was 77.87, 12.66 and 12.97%, respectively. Conclusions: These results revealed that all extracts of Ancorina sp. have strong or moderate cytotoxicity and have the ability to induce apoptosis on T47D human breast cancer cell line. However, methanol crude extract has high efficacy to induce apoptosis through caspase-3 activation compared to the other extracts. Hence methanol extract warrants further investigation as a natural medicine for human breast cancer.

Abstract
The environment of marine occupies about 95% biosphere of the world and it can be a critical source of bioactive compounds for humans to be explored. Special environment such as high salt, high pressure, low temperature, low nutrition and no light, etc. has made the production of bioactive substances different from terrestrial organisms. Natural ingredients secreted by marine-derived bacteria, fungi, actinomycetes, Cyanobacteria and other organisms have been separated as active pharmacophore. A number of evidences have demonstrated that bioactive ingredients isolated from marine organisms can be other means to discover novel medicines, since enormous natural compounds from marine environment were specified to be anticancer, antibacterial, antifungal, antitumor, cytotoxic, cytostatic, anti-inflammatory, antiviral agents, etc. Although considerable progress is being made within the field of chemical synthesis and engineering biosynthesis of bioactive compounds, marine environment still remains the richest and the most diverse sources for new drugs. This paper reviewed the natural compounds discovered recently from metabolites of marine organisms, which possess distinct chemical structures that may form the basis for the synthesis of new drugs to combat resistant pathogens of human life. With developing sciences and technologies, marine-derived bioactive compounds are still being found, showing the hope of solving the problems of human survival and sustainable development of resources and environment.

Abstract
Marine sponges continue to serve as a rich source of alkaloids possessing interesting biological activities and often exhibiting unique structural frameworks. In the current study, chemical investigation on the marine sponge Pericharax heteroraphis collected from the South China Sea yielded one new imidazole alkaloid named naamidine J (1) along with four known ones (2-5). Their structures were established by extensive spectroscopic methods and comparison of their data with those of the related known compounds. All the isolates possessed a central 2-aminoimidazole ring, substituted by one or two functionalized benzyl groups in some combination of the C4 and C5 positions. The cytotoxicities against selected HL-60, HeLa, A549 and K562 tumor cell lines and anti-H1N1 (Influenza a virus (IAV)) activity for the isolates were evaluated. Compounds 1 and 2 exhibited cytotoxicities against the K562 cell line with IC50 values of 11.3 and 9.4 μM, respectively. Compound 5 exhibited weak anti-H1N1 (influenza a virus, IAV) activity with an inhibition ratio of 33%.

Abstract
BACKGROUND Natural products isolated from marine environments are well known for their pharmacodynamic potential in diverse disease treatments, such as for cancer or inflammatory conditions. Sea cucumbers are marine animals of the phylum Echinoderm and the class Holothuroidea, with leathery skin and gelatinous bodies. Sponges are important components of Persian Gulf animal communities, and the marine sponges of the genus Haliclona have been known to display broad-spectrum biological activity. Many studies have shown that sea cucumbers and sponges contain antioxidants and anti-cancer compounds. OBJECTIVES This study was designed to determine the selective toxicity of Persian Gulf sea cucumber (Holothuria parva) and sponge (Haliclona oculata) methanolic extracts on liver mitochondria isolated from an animal model of hepatocellular carcinoma, as part of a national project that hopes to identify novel potential anticancer candidates among Iranian Persian Gulf flora and fauna. MATERIALS AND METHODS To induce hepatocarcinogenesis, rats were given diethylnitrosamine (DEN) injections (200 mg/kg i.p. by a single dose), and then the cancer was promoted with 2-acetylaminofluorene (2-AAF) (0.02 w/w) for two weeks. Histopathological evaluations were performed, and levels of liver injury markers and a specific liver cancer marker (alpha-fetoprotein), were determined for confirmation of hepatocellular carcinoma induction. Finally, mitochondria were isolated from cancerous and non-cancerous hepatocytes. RESULTS Our results showed that H. parva methanolic extracts (250, 500, and 1000 µg/mL) and H. oculata methanolic extracts (200, 400, and 800 µg/mL) increased reactive oxygen species (ROS) formation, mitochondrial membrane potential (MMP), mitochondrial swelling, and cytochrome c release in the mitochondria obtained from cancerous hepatocytes, but not in mitochondria obtained from non-cancerous liver hepatocytes. These extracts also induced caspase-3 activation, which is known as a final mediator of apoptosis, in the hepatocytes obtained only from cancerous, not non-cancerous, rat livers. CONCLUSIONS Our results suggest that H. parva and H. oculata may be promising therapeutic candidates for the treatment of HCC, following further confirmatory in vivo experiments and clinical trials.

Abstract
Marine sponges are currently one of the richest sources of anticancer active compounds found in the marine ecosystems. More than 5300 different known metabolites are from sponges and their associated microorganisms. To survive in the complicated marine environment, most of the sponge species have evolved chemical means to defend against predation. Such chemical adaptation produces many biologically active secondary metabolites including anticancer agents. This review highlights novel secondary metabolites in sponges which inhibited diverse cancer species in the recent 5 years. These natural products of marine sponges are categorized based on various chemical characteristics.

Comparative analysis of protein profiles of aqueous extracts from marine sponges and assessment of cytotoxicity on different mammalian cell types. ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2014; 38:1007-1015. [PMID: 25461562 DOI: 10.1016/j.etap.2014.10.021] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2014] [Revised: 10/20/2014] [Accepted: 10/26/2014] [Indexed: 06/04/2023]
Abstract
Marine natural products extracted from sponges represent a new source for drug discovery. Here we describe a simple method for preparing aqueous extracts from 7 Mediterranean demosponges, which allowed the extraction of water-soluble compounds, such as proteins by homogenization of sponge tissue in phosphate buffered saline (PBS). The comparative analysis by SDS-PAGE showed differences in number of bands, bandwidth and intensity among the sponges analyzed. The PAS/silver staining revealed a substantial and different glycoprotein assortment among the demosponges studied. To further study the biological activities present in the sponge extracts, we determined the non-cytotoxic doses on four different mammalian cell types demonstrating that the optimal non-cytotoxic doses were cell type- and extract-dependent. In conclusion, the extraction method described in this paper represents a fast and efficient procedure for the extraction of water-soluble proteins from marine sponges. Furthermore, the cell viability data suggest the feasibility of this method for the direct in vitro cell-based assays.

Abstract
Abstract
Objectives
Based on previous screening results, the cytotoxic effect of the hexane (JDH) and ethyl acetate extracts (JDE) of the marine sponge Jaspis diastra were evaluated on HeLa cells and the present study aimed at determining their possible mechanism of cell death.
Methods
Nuclear staining, membrane potential change, flow cytometry analysis of cell cycle distribution and annexin V staining were undertaken to investigate the effects of JDE and JDH. Electrospray ionization mass spectrometry (ESI-MS) and nuclear magnetic resonance were used to characterize an isolated bioactive molecule.
Key findings
JDE displayed an IC50 25 times more significant than the JDH. Flow cytometry analysis revealed JDE induced apoptosis in HeLa cells accompanied by the collapse of mitochondrial membrane potential. Fractionation of JDE resulted in the isolation of the known cytotoxic cyclodepsipeptide, Jaspamide.
Conclusions
Taking our results together suggest that JDE can be valuable for the development of anticancer drugs, especially for cervical cancer. Further investigations are currently in progress with the aim to determine and isolate other bioactive compounds from this extract.

Abstract
Marine sponges are considered as a gold mine of new natural products possessing numerous biological activities. We examined the cytotoxic properties of the ethyl acetate extract (JDE) of the previously unrecorded sponge, Jaspis sp. collected from Mauritius Waters. JDE displayed an interesting IC50 of 0.057±0.04μg/mL on HL-60 cells evaluated by MTS assay. Mitochondrial membrane potential change, microscopic analysis and DNA fragmentation assays also confirmed JDE induced apoptosis on HL-60 cells. Annexin V staining demonstrated that JDE induced apoptosis at different concentrations. Treatment with 100ng/mL of JDE led to an accumulation of cells in G2/M phase after 24 h, causing a significant increase of cells (24h: 5.84%; 48h: 13.41%) in sub-G1 phase suggesting that JDE can induce cell cycle arrest in G2/M phase.

Abstract
As part of our ongoing studies on bioactive natural products from marine sponges, we investigated the cytotoxic potential of extracts from the new sponge Petrosia tuberosa sampled from Mauritius waters. Bioguided fractionation of the ethyl acetate extract by vacuum liquid chromatography (VLC) revealed two fractions, namely VLC (6-9) and (13-17) showing cell deaths of 86 ± 1% and 88 ± 4%, respectively, at 50 μg/mL on HeLa cells. At 10 μg/mL, only VLC (13-17) displayed a significant cell death (56 ± 7%) compared with VLC (6-9) (8 ± 1 %). The cytotoxic activity of VLC (13-17) was also determined on nine other human cancer cell lines. Clonogenic assay, mitochondrial membrane potential change, DNA fragmentation and microscopic analysis of fraction VLC (13-17) revealed distinct features of apoptosis on HeLa cells. Further fractionation and purification of this fraction by chromatographic techniques resulted in isolation of one known secondary metabolite, petrosynol. Its structure was determined by 1H and 13C-NMR analyses.
