Embodiments and methods for a new class of potent non-peptidic covalent inhibitors of nsP2 cysteine protease that inhibit Venezuelan equine encephalitis virus's (VEEV) replication in neuroblasts are disclosed. More particularly, an acrylate and vinyl sulfone-based chemical series were investigated as promising starting scaffolds against VEEV and as inhibitors of the cysteine protease domain of VEEV's non-structural protein 2 (nsP2). The invention discloses compounds of Formula I and analogues for treatment of VEEV.
