Tozorakimab (MEDI-3506) is a human immunoglobulin G1 monoclonal antibody targeting IL-33. It inhibits IL-33 signaling through ST2 and RAGE/EGFR, reduces inflammation and epithelial dysfunction, and can be used to study chronic obstructive pulmonary disease.

GK921 is a transglutaminase 2 (TGase) inhibitor.

The Staphylococcus aureus transpeptidase Sortase A (SrtA) anchors virulence and colonization-associated surface proteins to the cell wall. SrtA selectively recognizes a C-terminal LPXTG motif. SrtA readily reacts with its native substrate Abz-LPETG-Dap(DNP)-NH2, cleaving it and catalyzing the formation of an amide bond between the carboxyl group of threonine and the amino group of cell-wall crossbridges.
