In an in silico study, Cura et al. [57] evaluated the interaction of thymol with HSV-1 and showed that hydrogen bonds were formed between thymol and the viral glycoproteins gB (i.e., amino acids GLN416, LEU228, and GLU42) and gD (i.e., amino acids PRO172 and ARG174); these interactions could interfere with viral adhesion and penetration into hosts cells, thereby preventing the early steps of the infection process. Here, PAEP is linked to infection.
