We previously tested two angiotensin-converting enzyme (ACE) inhibitors and two dipeptidyl peptidase-4 (DPP-4) inhibitors for dual enzyme inhibitory effect. Only two DPP-4 inhibitors, linagliptin and sitagliptin, were able to inhibit ACE. In the present study, we investigated if other inhibitors of ACE or DPP-4 could simultaneously inhibit the activities of both DPP-4 and ACE. Forty Sprague Dawley rats were used. The control group received saline only. The other three groups were treated with anagliptin, ramipril, or lisinopril. T
