In those early days, several DPP-4 inhibitors had been described ( in vivo DPP-4 inhibition was associated with enhanced intact GLP-1 responses to glucose challenges ( Metabolic Effects of DPP-4 Related to Its Enzymatic Activity Despite DPP-4 having a relatively restricted substrate preference (Figure 1), a large number of peptides, proteins, and chemokines still fulfill the criteria and could be predicted to be suitable substrates, and indeed, many have been shown to be cleaved by DPP-4 in pharmacological kinetic, in vitro or animal studies, often using high substrate concentrations ( can cleave a substrate in vitro does not necessarily mean that DPP-4 plays an important physiological role in regulating concentrations and/or modulating biological activity of the endogenous molecules, particularly in humans and, for many of these putative substrates, there is little, if any experimental evidence to show that DPP-4 does actually cleave them in vivo and/or whether this has any physiological consequence
