Ac-WEHD-AFC is a fluorogenic substrate for group I caspases including caspase-1, -4, and -5. Caspase activity can be quantified by fluorescent detection of free AFC (7-amino-4-trifluoromethylcoumarin), which is excited at 400 nm and emits at 505 nm.

N-Acetyl-L-tryptophyl-L-α-glutamyl-L-histidyl-N-[2-oxo-4-(trifluoromethyl)-2H-1-benzopyran-7-yl]-L-α-asparagine is a fluorogenic substrate that can be cleaved by group I caspases.
