2S-alkyne is an irreversible and clickable inhibitor of Streptococcal pyrogenic exotoxin B (SpeB) with IC50 of 1.4 uM; 2S-alkyne showed irreversible enzyme inhibition in biochemical assays and labeled endogenous SpeB in cultured S. pyogenes supernatants. 2S-alkyne decreased S. pyogenes survival in the presence of human neutrophils and supports the role of SpeB-mediated proteolysis as a mechanism to limit complement-mediated host defense.
