GAG can also be tailored to elicit specific bioactivities. Reported specific examples include the modification of heparin-like structures against for example dengue and flaviviruses [59], herpes simplex 1 and 2 viruses [60]. GAG-derived drugs can act as a decoy target for viral recognition [61] and therefore prevent cell membrane interaction that will allow virus entry into the host cell [62]. They also facilitate cell adhesion, cell growth, and differentiation, as well as cell signaling and anticoagulation [55].
