Marine Natural Products from the Russian Pacific as Sources of Drugs for Neurodegenerative Diseases.

Neurodegenerative diseases are growing to become one of humanity's biggest health problems, given the number of individuals affected by them. They cause enough mortalities and severe economic impact to rival cancers and infections. With the current diversity of pathophysiological mechanisms involved in neurodegenerative diseases, on the one hand, and scarcity of efficient prevention and treatment strategies, on the other, all possible sources for novel drug discovery must be employed.

Bioactive Compounds with Antiglioma Activity from Marine Species.

The search for new chemical compounds with antitumor pharmacological activity is a necessary process for creating more effective drugs for each specific malignancy type. This review presents the outcomes of screening studies of natural compounds with high anti-glioma activity. Despite significant advances in cancer therapy, there are still some tumors currently considered completely incurable including brain gliomas.

Antitumor potential of carrageenans from marine red algae.

Marine algae are abundant and inexhaustive sources of the bioactive compounds with the various benefits for human health. Among these substances an attention is given to the sulfated polysaccharides presented as the complexes of polymer macromolecules with excellent biological features including antioxidant, anti-inflammatory anticoagulant, antiviral, and immunomodulatory activities. In addition to the aforementioned properties there is a growing number of research results suggesting the bioactive sulfated polysaccharides such as carrageenan, fucoidan, laminarin, and others exert anticancer and antimetastatic properties.
