Brown alga Fucus evanescens, widespread in the Far Eastern seas of Russia, is valuable source sulfated polysaccharides – fucoidans with beneficial biological activities. The most homogenous fraction fucoidan from F. evanescens was shown to be molecule containing linear main chain alternating 2-sulfated 1,3- and 1,4-linked α-L-fucose residues. Few sulfate groups were found position 4 some 1,3-linked fucose Acetyl occupied free C-3 residues and/or C-4 Enzymatic hydrolysis, mild acid hydrolysis...

Abstract Structural characteristics and the antitumor activity of fucoidans isolated from vegetative reproductive tissue brown algae Alaria sp. Saccharina japonica were studied. The status affected yield their structural characteristics. fucoidan was 5.7% ( w / on basis dried weight) for fertile 3.8% sterile 1.42 0.71% S. , respectively. had a slightly higher degree sulfation somewhat more homogeneous monosaccharide composition, with predominate amounts fucose galactose, than those tissue....

Objective. To study the effect of fucoidan from brown algae S. feldmannii (SfF2) on metabolism MDA-MB-231 breast cancer cells. Materials and methods. The bioenergetic potential cells was assessed under influence various factors (insulin, epidermal growth factor, phorbol ester, X-rays) stimulating tumor progression. metabolically oriented SfF2 (200 µg/ml) colony formation process human determined using soft agar method normal conditions carcinogenic factors. Results. Fucoidan found to reduce...

Two new polyhydroxysteroidal glycosides, anthenosides A1 (1) and A2 (2), one previously known steroidal glycoside anthenoside A (3) were isolated from extract of the tropical starfish Anthenea aspera. Structures 1–3 determined by analysis spectroscopic data as well chemical transformations. As a result, structure has been revised structures 1 2 established. Glycosides contain 2-acetamido-2-deoxy-4-O-methyl-β-d-glucopyranosyl residue, found in glycosides for first time. All compounds slightly...
