Salicornolide B displayed five hydrogen-bonds with the amino acid residues of LYS254, ASP290, ARG438 and ARG520, with molecular distances of 2.702, 2.914, 3.435, 3.049, and 2.393 Å. Salicornolide C showed two hydrogen-bonds with amino acid residues of ASP285 and LEU244, with molecular distances of 3.172 and 2.846 Å.
