SSAA09E1 is an inhibitor of severe acute respiratory syndrome coronavirus (SARS-CoV) viral entry.1 It reduces infection of HEK293T cells transiently transfected with angiotensin-converting enzyme 2 (ACE2) by an HIV-based virus system pseudotyped with SARS-CoV surface glycoprotein (EC50 = 6.7 μM). SSAA09E1 also inhibits the proteolytic activity of cathepsin L (IC50 = 5.33 µM) but not cathepsin B when used at a concentration of 20 µM.

Novel inhibitors of severe acute respiratory syndrome coronavirus entry that act by three distinct mechanisms
J Virol 2013 Jul;87(14):8017-28.PMID:23678171DOI:PMC3700180
Severe acute respiratory syndrome (SARS) is an infectious and highly contagious disease that is caused by SARS coronavirus (SARS-CoV) and for which there are currently no approved treatments. We report the discovery and characterization of small-molecule inhibitors of SARS-CoV replication that block viral entry by three different mechanisms. The compounds were discovered by screening a chemical library of compounds for blocking of entry of HIV-1 pseudotyped with SARS-CoV surface glycoprotein S (SARS-S) but not that of HIV-1 pseudotyped with vesicular stomatitis virus surface glycoprotein G (VSV-G). Studies on their mechanisms of action revealed that the compounds act by three distinct mechanisms: (i) SSAA09E2 {N-[[4-(4-methylpiperazin-1-yl)phenyl]methyl]-1,2-oxazole-5-carboxamide} acts through a novel mechanism of action, by blocking early interactions of SARS-S with the receptor for SARS-CoV, angiotensin converting enzyme 2 (ACE2); (ii) SSAA09E1 {[(Z)-1-thiophen-2-ylethylideneamino]thiourea} acts later, by blocking cathepsin L, a host protease required for processing of SARS-S during viral entry; and (iii) SSAA09E3 [N-(9,10-dioxo-9,10-dihydroanthracen-2-yl)benzamide] also acts later and does not affect interactions of SARS-S with ACE2 or the enzymatic functions of cathepsin L but prevents fusion of the viral membrane with the host cellular membrane. Our work demonstrates that there are at least three independent strategies for blocking SARS-CoV entry, validates these mechanisms of inhibition, and introduces promising leads for the development of SARS therapeutics.
