この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。

2.000mg/ml (6.36mM) Taking the 1 mL working solution as an example, add 2 mg of this product to 1 ml of physiological saline (0.9% NaCL solution), mix evenly to make it clear, The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Loxistatin Acid (E-64C, NSC 694279, EP 475), a derivative of E-64, is an irreversible and membrane-permeant cysteine protease inhibitor. The cysteine protease cathepsin L is required for SARS-CoV-2 viral entry.
in vitro Loxistatin Acid (E-64C), as a thiol protease inhibitor, inhibits calpain activity in intact platelets. [1]It also inhibits β-secretase activity in regulated secretory vesicles of neuronal chromaffin cells, and decreases Aβ production, indicating a therapeutic strategy for Alzheimer's disease. [4]
in vivo In pectoral muscle of dystrophic chickens, Loxistatin Acid (E-64C) normalizes the increased activities of cathepsin B and cathepsin H. [2] This compound also inhibits ischemic degradation of cerebral proteins following occlusion of the middle cerebral artery in rats. [3]
