| Abstract | A sulfated galactan LP-G2 was isolated and purified from red alga, Pyropia hailanensis. It was a branched polysaccharide with average molecular weight about 8381 Da, composed of Gal, Glc, GalA and Ara. The structure of LP-G2 was determined using IR and NMR spectroscopy. It was composed of -> 4)-beta-D-galactose -> 4)-alpha-L-galactose-6-sulfate segments, with beta-D-Gk and alpha-D-galactose unit substituted at the &position of alpha-L-galactose. Functional analysis showed that LP-G2 inhibited complement activation on both the classic and alternative pathways with CH50 value of 3.08 = 025 mg/mL and AP(50) value of 223 +/- 020 mg/ml, respectively. Preliminary mechanism studies by using complement component depleted-sera indicated that LP-G2 selectively interacts with C1q, C2, C4 and C9. The results suggested that LP-G2 could be of potential benefits in treatment of the complement associated diseases. (C) 2020 Elsevier B.V. All rights reserved. |
