Inhibition of caspase-3 processing by Z-DQMD-FMK (Z-Asp(OMe)-Gln-Met-Asp(OMe)-fluoromethylketone) did not restore cell number in the zinc-deficient group, but resulted in processing of full-length PKC-δ to a 56-kDa fragment1.

The inhibitory effect of specific caspase inhibitors (Z-DQMD-FMK, Z-IETD-FMK and Z-LEHD-FMK) suggests that the MG132-induced apoptotic cell death and depletion of GSH in SCLC cells are mediated by both activation of caspase-8 and mitochondrial damage, leading to the activation of caspase-9 and -32.

To investigate whether εPKC cleavage after stroke is caused by caspase-3 activation, we examined the effect of a cell-permeable caspase-3–specific inhibitor, Z-DQMD-FMK, on generation of cleaved εPKC fragments. Caspase-3 inhibition did not suppress the decrease in fulllength εPKC and the 43-kDa fragment in the ischemic core and penumbra after stroke3.

Protocol

Cell experiment [1]:

Cell lines

3T3-Swiss Albino cells

Preparation method

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

Reacting condition

25 μM; 24 hrs

Applications

In zinc-deficient 3T3-Swiss Albino cells, Z-DQMD-FMK (25 μM) prevented activation of caspase-3. Z-DQMD-FMK treatment did not restore cell number, but resulted in processing of full-length PKC-δ to a 56-kDa fragment.
