Herencia and coworkers  studied the effects of dichloromethane and methanol extracts from some Mediterranean marine invertebrates on carrageenan-induced paw edema in mice. 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). Marine invertebrates (Porifera, Cnidaria, Mollusca, Arthropoda, Echinodermata, etc.) Many of these have excellent potential for drug development, but no commercial medication has been originated from them so far. 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]. Recently, sponge-derived actinomycetes and sediments isolated from marine sponge were tested for bioactive constituents with antifungal and antimicrobial activity. A number of new alkaloids were isolated from the marine sponge Agelas mauritiana: (+)-2-oxo-agela-sidine C, (−)-8′-oxo-agelasine D,4-bromo-N-(butoxymethyl)-1H-pyrrole-2-carboxamide, ageloxime B, and (−)-ageloxime D and some of these isolated components exhibited antifungal activity against Cryptococcus neoformans, antileishmanial activity in vitro and antibacterial activity against S. aureus and methicillin-resistant S. aureus in vitro . Although thousands of chemical compounds have been reported in the literature from these sponges, only few of them are clinically described. Compounds are listed in Table 6.

Hirudin substance is extracted from its saliva , It is used in making anticoagulant drugs and in treatment of inflammation of the middle ear . 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]. In the last decade studies reported that marine sponges could have been a source of hypocholesterolemic compounds. 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. Two important compounds: 4a-merhyl-5a-cholest-8-en-3~-ol and 4,5-dibromo-2-pyrrolic acid discovered by American scientist from deep water sponge Agelasfla bellrform is showed significant immunosuppressive activity. strains from Mediterranean sponges and secondary metabolite namely, cyclic depsipeptide valinomycin, indolocarbazole alkaloid staurosporine and butenolide, were screened for anti-infective activities. 1 mm, and moderate activity toward PfPK5, a member of the cyclin-dependent kinase (CDK) family . Once it was realized that biological systems would recognize the nucleoside base after modifications of the sugar moiety, chemists began to substitute the typical pentoses with acyclic entities or with substituted sugars, leading to the drug azidothymidine (zidovudine). It’s based on principles of collaboration, unobstructed discovery, and, most importantly, scientific progression. Marine organisms and microorganisms have provided a large proportion of the anti-inflammatory and natural antioxidants products over the last years. But in the sponge, scientists isolated two chemicals â aptly named spongothymidine and spongouridine â which were used as models for the development of a number of anti-viral and anti-cancer drugs.  extracted novel lysophosphatidylcholines from marine sponges with hypocholesterolemic properties and thereby aroused an interest of compounds from marine sponge due to short lifespan of conventional lysophosphatidylcholines in vivo.
