Bioactive marine biopolymers.

Bioactive marine natural products

Bioactive marine natural products can be defined as biologically active products, both secondary metabolites as well as enzymes, lipids and heteropolysaccharides derived from marine sources. Marine natural products have been found to be an important source of drugs and drug leads. These natural products are secondary metabolites and enhance survival fitness and may serve as chemical weapons use...

Developing Viable Carriers for Bioactive Molecules Using Biopolymers

In life sciences, many technological problems have known solutions, but what prevents them from being practical is the lack of successful means of administration. Treatments for malnutrition and cancer are notable examples. The commonality between possible solutions for these two conditions is the need for a carrier that is capable of maintaining stable architecture while releasing what it enca...

Bioactive metabolites from marine invertebrates

Recent results in the chemistry of bioactive marine products are presented. Concerning the cytotoxic a-carbolines : grossularins A and B, the mechanism of the toxicity using supercoiled DNA and synthesis of the imidazolo-a-carboline moiety are presented. In the polysulfur compounds series, the structure of lissoclinotoxin B is proposed as well as a new synthesis of pentathiepins. Novel sesquite...

Production of Biopolymers by Pseudomonas aeruginosa Isolated from Marine Source

Two bacterial strains, Pseudomonas aeruginosa CMG607w and CMG1421 produce commercially important biopolymers. CMG607w isolated from the sediments of Lyari outfall to Arabian Sea synthesize the mclpolyhydroxyalkanoates from various carbon sources. The production of PHAs was directly proportional to the incubation periods. Other strain CMG1421, a dry soil isolate, produced high viscous water abso...
