BB-Cl-Yne

BB-Cl-Yne is a cell-permeable derivative of the protein arginine deiminase (PAD) inhibitor BB-Cl-amidine (Cay-17079) that contains an alkyne moiety for use in click chemistry reactions. BB-Cl-Yne inhibits PAD1-4 with kinact/KI values of 6,400, 3,600, 10,800, and 4,900 M-1min-1, respectively. It has been used for labeling PADs in cell-free and cell-based assays, followed by click reactions with azide-modified TAMRA reporters or biotin capture reagents.Formal Name: N-[(1S)-1-(1H-benzimidazol-2-yl)-4-[(2-chloro-1-iminoethyl)amino]butyl]-4'-ethynyl-[1,1'-biphenyl]-4-carboxamide.
