Novel alpha- and beta-amino acid inhibitors of influenza virus neuraminidase.

abstract：:A new reverse transcriptase (RT) inhibitor was extracted and purified from the red alga Schizymenia pacifica. The chromatographic behavior and chemical properties of this sea algal extract (SAE) suggest that it is a sulfated polysaccharide having a molecular weight of approximately 2,000,000. SAE is composed of galact...
