| PEP-YL001 | Endogenous dipeptide, classic substrate for PEPT transporters, with antioxidant and mild ACE inhibitory activities | Tyrosylleucine is a natural dipeptide produced by hydrolysis of dietary and endogenous proteins. It is a classic model substrate for intestinal and renal dipeptide transporters PEPT1/PEPT2, widely used to study transmembrane absorption mechanisms, transporter kinetics and drug-drug interactions of dipeptides. Meanwhile, this dipeptide exhibits free radical scavenging ability and mild angiotensin-converting enzyme (ACE) inhibitory activity, exerting slight antioxidant and antihypertensive effects. It can also serve as a peptidase substrate for protease activity assays and protein degradation pathway research, serving as a basic tool molecule for nutritional physiology, peptide drug development and digestive metabolism research. | Peptide transporter research,Nutritional digestion and absorption study,Antioxidant research,Hypertension mechanism study,Protease activity assay,Protein degradation pathway study | Dipeptide transporters PEPT1/PEPT2; Angiotensin-converting enzyme (ACE); Dipeptidase hydrolysis pathway |
