Marine-Natural Compounds: Treatment Of Parkinson’s Disease

Parkinson’s disease (PD) is a common neurodegenerative disease that mainly occurs in the elderly. The main pathological changes of PD included the progressive loss of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNc); the decrease of dopamine content in the striatum, and the formation of α-synuclein aggregates in the brain. The death of…

Briareum violaceum

Anti- Inflammatory Activity Of Briareum violaceum

Briareum violaceum (Quoy and Gaimard, 1883) is a soft coral of the family Briareidae; which has found to contain cembrane-type diterpenoids in abundance. Diterpenoids of this type have reported to have complicated structures and possess a variety of bioactivities. Recently, in our research into the chemical constituents and properties of a cultured octocoral B. violaceum,…

Marine Sponge Spongosorites sp

Potent toxicity: Isolated From The Marine Sponge Spongosorites sp

Marine sponges are to be rich sources of novel bioactive peptides. They are mostly small cyclic molecules (molecular weight, MW < 2000) composed of non-proteinous amino acids or even non-amino acid components; thus are thought to of non-ribosomal origin. There are, however, several examples of middle-sized (MW < 6000) ribosomal peptides including polytheonamides, asteropines and…

Lymphatic Endothelial Cells: Phomaketide A Inhibits Lymphangiogenesis

Cancer metastasis enables cancer cells to spread from the primary tumor and establish themselves in other tissues. Lymphatic circulation is a common route for cancer metastasis; with the thin walls and few tight junctions in the lymphatic vessels offering good permeability. Moreover, the lack of basal lamina and associated pericytes means that lymphatic capillaries have…

Marine Bacterium

Marine Bacterium: The Microbial Origin Of The Bicyclic Guanidine Alkaloid

Various guanidine-containing natural products, isolated from different marine invertebrates; demonstrate antifungal, antibacterial, antiviral, and antitumor properties and are suitable compounds for drug development due to high levels of their bioactivities and water solubility. Moreover, some natural guanidine-containing compounds; such as streptomycin, have already introduced in the clinic. Most of the marine guanidine alkaloids found in…

Marine Algae Ecklonia maxima

A Neuroprotective Of Phlorotannin From The Marine Algae

Phlorotannins are the major phloroglucinol, polyphenols of wide occurrence among marine brown algae; these have extensively investigated for various biological activities such as antioxidant, anticancer, anti-inflammatory, anti-allergic, antidiabetic, antihypertensive, and neuroprotective effect. Ecklonia maxima is a brown seaweed that is along the west coast of South Africa. The leaves of E. maxima are frequently used…

The Potential Allergenicity Of Green Macroalga Ulva lactuca

Cardiovascular disease (CVD) is the main cause of death in Europe, and among CVD; hypertension has become a problem of global, epidemic proportions. Long-term hypertension results in increased risk of stroke, heart attack, arterial aneurysm, and kidney failure; even moderate hypertension can shorten the life span. Hypertension is a global problem that influences the health…

New Piperazine-Triones From A Marine-Derived Streptomycetes

Natural products have proved to a valuable source of new chemical entries in many therapeutic areas. Piperazine-triones are a rare class of natural products by fungi and actinomycetes. To date, only eleven polyketides bearing piperazine-triones motif have discovered in nature, including dithiodioxopiperazine; cytotoxic 12-dimethyl-12-oxodehydroechinulin and gliocladine C, lasiodiplines A. Actinomycetes characterized from the marine environment…

Sea cucumbers

Anticoagulant Activities Of The Polysaccharides From Sea Cucumber

Some sea cucumbers (Echinodermata, Holothuroidea) are popular tonic foods and traditional Chinese medicines in China for centuries. Sulfated polysaccharides such as fucosylated glycosaminoglycan (FG); fucan sulfate (FS) are the main components of polysaccharides extracted from sea cucumbers and have attracted considerable attention due to their unique structures and extensive bioactivities. FG is a distinct glycosaminoglycan…

Seafood

Neuroprotective Effect Of Polysaccharide From Viscera Autolysates

Squid is too important seafood; which is well for its wide varieties, wide spreading distribution, abundance, and fishing production. Meanwhile, it is representative of the increased waste production in the seafood industry. The resulting byproducts largely consist of the head, fin, wings, and viscera; which contain abundant natural proteins, lipids, and minerals. The marine bio-processing…
