Ki: 2 to 5 nM (Cathepsin B)[1] |
| In Vitro | CA-074 is a synthetic analogue of E-64, a natural peptidyl epoxide that irreversibly inhibits most known lysosomal cysteine proteinases, and is developed by means of rational drug design, exploiting the dipeptidylcarboxypeptidase activity of cathepsin B. CA-074 can be used to selectively inhibit cathepsin B within living cells, as long as the experimental conditions permit significant fluid-phase endocytosis of the drug[2]. CA-074 inhibits cathepsin B with a Ki of 2 to 5 nM, whereas the initial Kis for cathepsin H and L are about 40-200 μM. CA-074 exhibits 10000-30000 times greater inhibitory effects on purified rat cathepsin B than on cathepsin H and L[1]. |
| In Vivo | Intraperitoneally injection of compound CA-074 into rats potently and selectively inhibits cathepsin B activity[1]. Intravenously administration of CA-074 immediately after the ischaemic insult saves 67% of CA1 neurons from delayed neuronal death on day 5 in eight monkeys undergoing 20 min brain ischaemia: the extent of inhibition is excellent in three of eight and good in five of eight monkeys[3]. |
| Animal Admin | Rats: Compound CA-074 or CA-030 or E-64 is injected intraperitoneally as a solution in saline containing DMSO. A dose of 8 mg/100 g body weight is injected. The rats are killed by a blow to the head 6 h after the injection, and their liver is perfused with saline, removed, weighed and chilled on ice. Samples of 4 g of liver are minced and homogenized. The homogenate is centrifuged at 800 xg for 15 min and the supernatant is centrifuged at 12000 xg for 30 min. The precipitate is suspended in 2 mL of 0.05 M acetate buffer, pH 5,0, and freeze-thawed for measurements of cathepsin B, H and L activities[1]. |
