8645710-1	1996	A number of dipeptide diphenyl phosphonate esters were studied as inhibitors of dipeptidyl peptidase IV, focusing on the role of the P2 residue in the inactivation process.	dipeptide diphenyl phosphonate esters	12-49	dipeptidyl peptidase 4	Homo sapiens	80-103
8645710-5	1996	This indicates that, as in the case of trypsin-like proteinases, dipeptide diphenyl phosphonate esters form a covalent adduct with the catalytic site of DPP IV, even though this enzyme belongs to a completely distinct class of serine peptidases.	dipeptide diphenyl phosphonate esters	65-102	dipeptidyl peptidase 4	Homo sapiens	153-159
