| CAS:66852‑01‑5:Tyrosylleucine TFA | |
| Tyrosylleucine (Tyr‑Leu) is a simple natural dipeptide. It exerts free radical scavenging and antioxidant effects through the phenolic hydroxyl group of tyrosine, and can alleviate oxidative stress damage to cells; meanwhile, it has mild skin repair activity and can improve skin barrier status. The trifluoroacetate salt is an intermediate salt form during HPLC purification, with good water solubility. It can be used as skincare active ingredient, peptide synthesis building block and biological research control reagent. | |

| PEP-TYL001 | The antioxidant activity of tyrosylleucine mainly comes from the phenolic hydroxyl group of tyrosine residue. It can directly scavenge reactive oxygen species such as hydroxyl radicals and superoxide anions through hydrogen donation, reduce cell lipid peroxidation and protein damage caused by oxidative stress, and exert mild antioxidant protective effect. Its dipeptide structure has small molecular weight and can easily penetrate the skin stratum corneum, exerting local skin repair and barrier improvement effects. The dipeptide has mild activity, no strong pharmacological toxicity, and high safety, suitable for use as skincare raw material, synthesis intermediate and control reagent. |
