Figure 13.

The chemical structures of the monosulfated zosteric acid 46 and trisulfated gallic acid 47, both of which are NSGMs which demonstrate significant antifouling activities. Zosteric acid also inhibits the viral entry of dengue virus into host cells. The figure also depicts the chemical structure of 3-carboxy-4-hydroxybenzenesulfonate 48 which potentially inhibits CCL5-mediated leukocyte recruitment to the peritoneal cavity in the thiogallate-induce peritonitis mice model. Chemical structures of acamprosate 49, tramiprosate 50, eprodisate 51, and suramin 52 are also depicted.
