基本信息
| Empirical Formula【经验(实验)分子式】 | C20H38N6O4 · xC2HF3O2 |
| Molecular weight | 426.55 (free base basis) |
| MDL number | MFCD00133458 |
| PubChem Substance ID【PubChem化学物质编号】 | 329817397 |

| Biochem/physiol Actions【生化/生理作用】 | Inhibitor of serine and cysteine proteases. Inhibits plasmin, trypsin, papain, calpain, and cathepsin B. Does not inhibit pepsin, cathepsins A and D, thrombin, or α-chymotrypsin. Effective concentration 10-100 μM. There have been numerous studies using leupeptin to protect against hearing loss caused by acoustic overstimulation or the ototoxic antibiotic gentamicin. (Loss of cochlear hair cells is believed to be mediated by calpain.) |
| Analysis Note【分析说明】 | 由于三种形式在溶液中达到平衡，亮抑酶肽可在 HPLC 上形成多个峰。通过三个主峰测定纯度。主要的杂质肽为外消旋亮抑酶肽。 |
