| 应用 | Chymostatin has been used in a study that determined that molecular calculations are useful for evaluating the interactions between ligands, including inhibitors and homologous enzymes, in docking models. Chymostatin has also been used in a study to investigate the norovirus protease as an attractive target for antiviral drug development. |
| 产品介绍 | Chymostatin is a bioactive peptide protease inhibitor that contains chymostatin A as a major form. The compound specifically inhibits chymotrypsin (CTR) (ID50 = 150 ηg/ml), papain (ID50 = 7.5 μg/ml), and cathepsin G along with most cysteine proteases such as cathepsin A, B, H, and L. The compound has been noted as a strong inhibitor of cathepsins A, B, and C. Chymostatin at an effective concentration of 10 to 100 μM weakly inhibits human leukocyte Elastase-1. In rat muscle homogenates chymostatin inhibited the protease cathepsin B and other soluble Ca2+ activated proteases. In the same study, chymostatin decreased protein break down by 20-40% without inhibiting protein production. |
| 生化机理 | 抑制溶酶体组织蛋白酶 B 和可溶性钙激活蛋白酶。许多幼嫩的植物组织都表达一种胰凝乳蛋白酶抑制剂敏感性丝氨酸蛋白酶。 糜蛋白酶抑制蛋白是许多蛋白酶的强抑制剂，包括糜蛋白酶、木瓜蛋白酶、糜蛋白酶样丝氨酸蛋白酶、糜蛋白酶和溶酶体半胱氨酸蛋白酶如组织蛋白酶 A、B、C、B、H 和 L。它对人白细胞弹性蛋白酶的抑制作用较弱。在终浓度为 100～200 μg/ml (10～100 μM) 时有效。胰凝乳蛋白酶抑制剂通常包含在与植物提取物一起使用的蛋白酶抑制剂混合物中。 |
