The study is still in its early stages and is currently only being tested in mice. The results showed that after 25 minutes of contact time, the amount of active virus was dramatically reduced by the GSE and had been neutralized by xylitol. The team found a small group of molecules, including the N-0385, that might be able to prevent the spike protein from attaching to the cells in their studies on mice.
