| The antiviral potency of Caulerpa cupressoides (Chlorophyta) sulfated polysaccharidic fractions (Cc-SP1→3) associated with thrombin generation (TG) assay is unknown. This study analyzed the structure of Cc-SP1 and its effects against herpes viruses (HSV-1 and HSV-2), dengue-virus (DENV-1), human-metapneumovirus (HMPV) and adenovirus (AdV) in Vero and mosquito C6/36 cell-lines and as inhibitor of TG in 60-fold diluted human plasma using continuous system. Infrared analysis indicated ulvan containing 11% sulfate, 40.16% total sugars and 6% uronic acid. Procedures of agarose/polyacrylamide gels electrophoresis revealed two major components presenting sulfate and non SPs, with molecular dispersion ranging from 8 to > 100 kDa, respectively, as confirmed by... |
