| 产品描述 | Z-IETD-FMK (Z-IE(OMe)TD(OMe)-FMK) is a cell-permeable, irreversible inhibitor specific for caspase-8. Z-IETD-FMK also an inhibitor of granzyme B. Z-IETD-FMK exhibits cell permeability. Z-IETD-FMK can be used in studies of the extrinsic apoptosis pathway, pyroptosis, and programmed necrosis. |
| 体外活性 | 方法:人 PBMCs、纯化的 CD4⁺和 CD8⁺ T 细胞加入丝裂原 (PHA 5 μg/mL)和 Z-IETD-FMK (25, 50, 100 μM),处理 72 小时, [³H]-胸腺嘧啶掺入法检测 DNA 合成;CFSE 稀释法流式细胞术检测细胞分裂。 |
| 体内活性 | 方法: C57BL/6 小鼠,经鼻感染肺炎链球菌 D39 或耐碳青霉烯肺炎克雷伯菌,感染后 24 小时开始静脉注射 Z-IETD-FMK (6 mg/kg),每日一次,持续 5 天。 |
| 激酶实验 | Proteasome assay: Exponentially growing cells on a 96-well clustered plate are treated with different concentrations of drugs or left untreated (control) for 6 hours. Proteasomes extracted with 0.5% NP40 buffer are mixed with equal amounts of samples in 100 μL total volume, and then incubated with 25 μmol/L of fluorogenic substrates (LRR- specific for trypsin-like activity, LLE-specific for caspase-like activity, and SUVY-specific for chymotrypsin-like activity) in black-bottom 96-well plates at 37°C. Fluorescence is monitored every 5 minutes at the wavelength of 360 nm (excitation) and 480 nm (emission). |
