DAVEI Molecule (IMAGE) Drexel University Caption The Dual Action Virolytic Entry Inihibitor (DAVEI) molecule is comprised of two pieces: one called Membrane Proximal External Region (MPER) attaches to the viral membrane; the other, called cyanovarin (CVN) bonds with the virus's protein spike. The molecule is able to make the virus react as if it is attached to a healthy cell -- firing its protein spike and injecting its RNA into oblivion, thereby rendering it inert.
