al. identified 18 small molecules that targeted the S-ACE-2-mediated entry of virus into human cell.[53] In 293T cells expressing ACE-2, one of these agents (VE607) showed a significant inhibition of SARS-pseudovirus entry.[53] In Vero E6 cells, two other molecules tetra-O-galloyl beta-D-glucose and luteolin also inhibited SARS-pseudovirus and SARS-CoV infection.[53] In virus-infected Vero E6 cells, a siRNA against the S sequence
