Protocol

Cell experiment [1]:

Cell lines

C57BL/6 mice renal endothelial cells

Preparation method

The solubility of this compound in DMSO is >11.65 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

100 μM for 3 h

Applications

Renal EC apoptosis after 4 h of TNF exposure was strongly inhibited by pretreatment with the broad-spectrum caspase inhibitor Boc-D-fmk, as well as caspase-3 inhibitor z-DQMD-fmk. Pretreatment with broad-spectrum caspase inhibitor Boc-D-fmk significantly inhibited TNF-induced ICAM-1 and VCAM-1 mRNA expression.

Animal experiment [2]:

Animal models

Male Sprague–Dawley rats

Dosage form

1.5 mg/kg, i.p.

Application

When compared with sham operation, common bile duct ligation with ZFA-fmk (placebo) significantly increased hepatocyte apoptosis. When compared with the OBZFA group, Boc-D-FMK significantly diminished the increased hepatocyte apoptosis in the OBBOC-D group. There is no difference in hepatocyte apoptosis between OBBOC-D and SHAM groups. After endotoxin challenge, the 48 h survival rates were 100%, 87.5% and 62.5% for the SHAM, OBBOC-D and OBZFA groups, respectively。

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Boc-D-FMK is a cell-permeable broad-spectrum caspase inhibitor that fully inhibits the pro-apoptotic effect of tumor necrosis factor-α (TNFα) with the half maximal inhibition concentration IC50 value of 39 μM [1].

Boc-D-FMK has been found to reduce the activation of nuclear factor kappa light chain enhancer of activated B cells (NF-kB), suppress the phosphorylation of subunit nuclear factor kappa light polypeptide gene enhancer in B cells inhibitor α (IkBα) and inhibits TNF-induced expression of intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) [2].

Moreover, Boc-D-FMK has also effectively attenuated the hepatocyte apoptosis in bile duct-ligated rats potentially improving the survival rates [3].
