medical importance of sponges - Piano Notes & Tutorial

Gelatin has a long and varied history in medicine, going back as far as 1834. Sponges feed on microscopic organisms (protozoa, bacteria and other small organisms in water) and organic particles [3]. The compounds, namely haminols, saraine and 3-alkylpyridinium salts extracted from Reniera sarai, Haliclona sp. More than 5300 different natural products are known from sponges and their associated microorganisms, and every year hundreds of new substances are discovered. To date our community has made over 100 million downloads. Open Access is an initiative that aims to make scientific research freely available to all. Later, various reputed pharmaceutical companies joined hands for this effort using more advance assay systems, including enzyme inhibition assays. Fungicides which are presently being used are less diverse than antimicrobials, and the usage of many of them is restricted because of their toxic effects to animals, plants and humans. The first discovered antibiotic from a marine sponge was manoalide, a seterterpenoid isolated from Luffariella variabilis [82]. sponges used for skin prep should be thrown into the waste container to avoid being mixed in with counted sponges. Sponges belong to Phylum Porifera and its name derived from the Latin terms Porus which is pores and Ferre for bear. Sponges are generally hermaphroditic (that is, having male and female germ cells in one animal); however, some sponge species are sequential hermaphrodites (that is, having male and female germ cells that develop at different times in the same animal). Adociaquinone B and 3-ketoadociaquinone B were the most potent inhibitors of the Cdc25 B phosphatase inhibitory activities, and the dihydro-benzothiazine dioxide in compounds Adociaquinone A, Adociaquinone B, 3-Ketoadociaquinone A, and 3-Ketoadociaquinone B appeared to be an important structural feature for this enhanced activity. A sponge is a sessile, sedentary, filter-feeding primitive aquatic invertebrate animal which attaches itself to solid surfaces from intertidal zone to depths of 29,000 ft (85000m) or more, where they can get sufficient food to grow [1, 2]. Sponges have 3000 species around the world. Marine invertebrates (Porifera, Cnidaria, Mollusca, Arthropoda, Echinodermata, etc.) Also includes diterpenes of (8E, 13Z, 20Z)-strobilinin and (7E, 13Z, 20Z)-felixinin from a marine sponge Psammocinia sp. BMC Med Educ. They are very diverse and occur in various colors, sizes and shapes such as tubular (tube-like), globular (ball-shaped), caliculate (cup-shaped), arboresecent (plant-shaped), flabellate (fan-shaped) and amorphous (shapeless). This chapter covers extensive work published regarding new compounds isolated from marine sponges and biological activities associated with them. Both compounds were found significantly active in suppression of the response of murine splenocytes in the two-way mixed lymphocyte reaction (MLR) with little to no demonstrable cytotoxicity at low doses ([196]. In contrast to the experiments of Hill et al. Built by scientists, for scientists. Recently natural constituents isolated from marine sponges were tested for immunosuppressive activities and in the end of 1980s, deep water marine sponges resulted in isolation of pure compounds with immunosuppressive properties. Various antibacterial substances were identified from marine sponges by continuous efforts of marine natural product community. can contribute the search for novel antibiotics to overcome infections and also for the production of potential immunomodulators [109]. In contrast, four xestoquinone analogs in which the quinine structure was converted to quinol dimethyl ether did not inhibit the Ca2+ ATPase activity [186]. Frogs are used to make some types of medication and thus can be sold for this purpose. Biological and Medicinal Importance of Sponge. 5) Ecological and economical importance of Porifera is that it is in all aquatic habitats, microbial sumbionts, and creates habitats for other organisms, sponge beds are also “hotspots” for diversity. We share our knowledge and peer-reveiwed research papers with libraries, scientific and engineering societies, and also work with corporate R&D departments and government entities. exhibited antibacterial activity against 61% of the coagulase-negative staphylococci (CNS) strains, including strains resistant to conventional antibiotics. In fact, sponges, sea whips, sea squirts and similar animals are the source of most of the invertebrate-derived medicines in use today. The immunomodulatory potential was evaluated by oral administration of ethyl acetate extract of marine sponge (200 mg/kg) to Wistar rats and the results obtained showed that extracts exhibited immunosuppressant activity and can further be studied [197]. The results showed majority of the tested compounds were active against at least two of the applied test systems [152]. strains from Mediterranean sponges and secondary metabolite namely, cyclic depsipeptide valinomycin, indolocarbazole alkaloid staurosporine and butenolide, were screened for anti-infective activities. absorbable gelatin sponge a sterile, absorbable, water-insoluble, gelatin-base material used in the control of bleeding. The economic is that they can absorb water and filter shit, Medicine. Several papers reports the screening results of marine organisms for antiviral activity, and a diverse range of active constituents have been isolated and characterized from them [80, 103, 104]. By George Andrei Draghici, Cristina Deheleana, Razvan Susan, Delia Berceanu-Văduva and Dragoş Nica. Marine sponges are among the richest sources of interesting chemicals produced by marine organisms. A novel polycyclic guanidine alkaloid monanchocidin isolated from Monanchora pulchra marine sponge reported to induce cell death in human cervical cancer (HeLa),human monocytic leukemia (THP-1)and mouse epidermal (JB6 Cl41) cells [25]. Moreover marine sponges are the important source for vital diverse bioactive constituents including alkaloids, terpenoids, sterols and macrolides. 25 Gy. By Musarat Amina and Nawal M. Al Musayeib, Submitted: June 4th 2017Reviewed: January 5th 2018Published: April 25th 2018, Home > Books > Biological Resources of Water. Brief introduction to this section that descibes Open Access especially from an IntechOpen perspective, Want to get in touch? For example, lysophosphatidylcholines and lyso-PAF analogs derived from Spirastrella abata are reported as successful inhibitors of cholesterol biosynthesis in vitro study [198, 199]. The preclinical results reported that Renieramycin M, a natural constituent from sponge induced lung cancer cells apoptosis through p53-dependent pathway and may inhibit progression and metastasis of lung cancer cells [24]. The can be used to remove biofilm from the teeth and soft tissues of the oral cavity such as the tongue, palate and cheeks. Ara-A has been used for the treatment of herpes virus infections, but it is less efficient and more toxic than acyclovir [107, 108]. a few chemical substances secreted by sponges have anti-inflammatory, anti-tumoral activities and antibiotic and they are used in the production of medicines, Since ancient times the endoskeleton of some sponges has had commercial value they are used as cleansing implements for baths (bath sponges), to wash animals, objects etc. Help us write another book on this subject and reach those readers. Antifungal Cyclic Peptides from the Marine Sponge Microscleroderma sp. In the recent years, interest in marine sponges has risen considerably due to presence of high number of interesting biologically active natural products. Thus the bacterial actinomycetes from marine sponges and other marine organisms have been proved prolific producers of pharmacologically active compounds. A number of new metabolites with antibiotic applications are discovered every year, but in marine sponges their ubiquity is remarkable. Sponge care swabs are on a Medical Device Alert in England and are banned in Wales. Studies revealed that the crude extracts of marine sponge have shown high incidences of antibacterial activity against terrestrial pathogenic bacteria, but very low incidences of antibacterial activity against marine bacteria [77, 78]. and Cinachyrella sp. Perhaps the most important antiviral lead of marine origin reported thus far is the nucleoside ara-A (vidarabine) isolated from the sponge Cryptotethya crypta. Spongistatin a macrocyclic lactone polyether isolated from Spongia sp. The scientific term for sponges is Porifera meaning “pore-bearing” and has bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two layers of cells [5]. Very few cases of sponge infection by exogenous microorganisms are known, presumably due to the accumulation/or product by the marine sponges of substances which have antimicrobial activity [1]. A collaborative program between experimental therapeutics laboratory of Henry Ford Hospital in Detroit and University of California Santa Cruz initiated in 1990 focused on the development and discovery of anticancer drugs from sponge extracts. They are the most primitive types of animals in existence, featuring a cell-based organization where different cells have different tasks, but do not form tissues. Herencia and coworkers [156] studied the effects of dichloromethane and methanol extracts from some Mediterranean marine invertebrates on carrageenan-induced paw edema in mice. Several ecological studies reported that high quantity of bioactive constituents produced by sponges often serve defensive against environmental threats such as predation, microbial infection, competition for space or overgrowth by fouling organisms [15, 16]. Therefore, marine sponges are considered a rich source of chemical diversity and health benefits for developing drug candidates, nutritional supplements, cosmetics, and molecular probes that can be supported to increase the healthy life span of humans. Ara-A, ara-C (1-β-Darabinosyl cytosine, cytarabine), acyclovir, and azidothymidine are in clinical use and are all examples of products of semisynthetic modifications of the arabinosyl nucleosides [106]. In a recent study structurally different compounds containing 3-alkylpyridine moiety were evaluated for antifouling potential. Out of 15 prepared active extract nine were found active against Enterococcus fascism (vancomycin-resistant) and Candida albicans multidrug-resistant [132], including strains resistant to conventional antibiotics. In addition, broad-based antiviral agents such as 2-5A and α-glucosidase inhibitors may be useful in cases of sudden outbreaks of (less familiar) viruses such as SARS and Ebola [80]. Platyhelminthes, better known as flatworms, play important roles in marine, freshwater and terrestrial ecosystems, and several species are dangerous parasites of humans. Antioxidant activity of (8E,13Z,20Z)-strobilinin/(7E,13Z,20Z)-felixinin from a marine sponge Psammocinia sp. About 2036 extracts from 683 individual sponges were examined by using novel in vitro assay led to the identification pure bioactive compounds from many sponges for treating solid tumors. Also, over the years marine sponges are considered as a rich source of natural products and metabolites for antibiotics possessing strong inhibitory against bacteria, fungi and microbes. Compound xestoquinone inhibited both Ca2+ and K+-ATPase of skeletal muscle myosin [185]. How? marine sponge in 1993 was shown to inhibit microtubule assembly, mitosis, and the binding of tubulin to vinblastine thereby inducing cytotoxic cell death in numerous cancer cell lines [27, 28]. Thus the possibility of development of new anticancer drugs for curing or reducing cancer is promising. It benefits in blood distribution in high efficiency during patching operation … Medical importance of leech worms. Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too. Scientists working in the field of natural product chemistry and research suggest that these sponges have promising potential to provide future drugs which can serve various diseases. Nowadays it’s a common material used in a number of pharmaceutical and biomedical applications around the world. Many studies revealed that sponge-derived metabolites are used directly in therapy or as a prototype of bioactive leads to develop more active and less toxic analogs [11, 12]. But still, there is much demand for the natural sponge. In the recent years many scientific studies provided evidences for marine sponge metabolites with efficient antibiotic, antibacterials and antimicrobial properties. As a result of all these investigations, bioassay-directed separation of active extracts identified many structurally diverse compounds as future leads. Another marine sponge component, heteronemin a sesterterpene isolated from Hyrtios sp. Antifungal compounds isolated from marine sponges are listed in Table 4. Marine sponges have been considered a gold mine for the discovery of marine natural products during the past 50 years. Antifungal compounds from marine sponges and their effects. Anti-inflammatory compounds from marine sponges and their effects. Medicine from the Sea From slime to sponges, scientists are plumbing the ocean’s depths for new medications to treat cancer, pain and other ailments By Staff Writer Last Updated Apr 14, 2020 2:38:10 AM ET. Plethora of secondary metabolites is produced by marine sponges and their symbionts. These medical Sponges are ideal for specialist's offices, surgery centers, clinics and hospitals, and for pateint care at home. Examples of anti-inflammatory compounds marine sponge origin are presented in Table 5. Integrating patient safety education into early medical education utilizing cadaver, sponges, and an inter-professional team. Halichondria okadai has achieved success in phase III clinical trials. It was demonstrated that endotoxin-free samples of marine origin possess effects on certain components of the immune system. All the isolated compounds along with Streptomyces sp. One of the major causes of death in patients suffering from malignant disease is fungal infections and emerging resistance is also an important problem. Marine sponges have attracted growing attention as a source of overwhelming structurally diverse secondary metabolites with potential biological activities and were placed at the top with respect to discovery of biologically active chemical constituents [9, 10]. Sponges play a vital role in the economic and comercial growth of our society. Musarat Amina and Nawal M. Al Musayeib (April 25th 2018). The soft bristles make this product a suitable replacement to the mouth sponges. What Is the Importance of Platyhelminthes? Isolation of isonitriles ditepene from Cymbastela hooperi, tropical marine sponge and the axisonitrile-3 sesquiterpene isolated Acanthella kletra, from the tropical marine sponge were tested for series of bioassays antibacterial, antiphotosynthetic, antifouling, antialgal, antifouling, antialgal, antiphotosynthetic, antifungal, and antitubercular. Bioactive constituents are claimed for potent in vivo or in vitro activity against infectious and parasitic diseases, such as bacterial, fungal, viral and protozoan infections. Bacterial biofilms are surface-attached microorganism’s communities that are protected by an extracellular matrix of biomolecules. 1. Moreover, the extensive ongoing research on sponges and development of new advanced techniques have made it possible to access deep sea, new anticancer marine isolates with unprecedented carbon skeleton and inhibitory activities of human cancer cell continued to be discovered and developed, which will offer in future the new candidate for cancer therapy. Xestospongic acid ethyl ester (207) was found to inhibit the Na+/K+ ATPase [190]. Sponges (Porifera) are a predominantly marine phylum living from the intertidal to the abyssal (deepest ocean) zone. Screening for immune response modifiers from marine origin, Marine Pyridoacridine Alkaloids: Biosynthesis and Biological Activities, Immunomodulating Properties of Bioactive Compounds Present in Aurora globostellata
