Affinity scores determined by molecular coupling (AutoDock), as well as the inhibition constants (Ki), and interaction distance between the boron residue and Serine 624 of the fibroblast activation protein (FAP) for each boroPro ligand.

Ligand: boroPro	Affinity (kcal/mol)	Ki (nM)	Distance Ser624-Boro (Å)
N-acyl-Gly-boroPro	−4.80	296.46	3.398
N-(pyridine-4-carbonyl)-D-Ala-boroPro)	−6.60	14.07	3.657
iFAP	−8.53	0.536	3.274
