产品介绍
Caspase-6 inhibitor

Cell lines

Luteal cells

Preparation method

Soluble in DMSO. 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.

Reaction Conditions

50 μM; 6 h

Applications

Incubation of luteal cells in the presence of inhibitors of caspase-3 (Z-DEVD-FMK), caspase-6 (Z-VEID-FMK), caspase-8 (Z-IETD-FMK) and a general caspase inhibitor (Boc-DFMK) resulted in a reduction in the level of TNFα-induced DNA fragmentation.

产品描述

When compared to other caspase inhibitors, Z-DRHD-FMK inhibited caspase 6 activity more effectively than the general caspase inhibitor Z-Val-Ala-Asp (OMe)-fluoromethy ketone (Z-VAD-FMK) or the caspase 6 inhibitor Z-Val-Glu(Ome)-Ile-Asp(OMe)-fluoromethyl ketone (Z-VEID-FMK). However, it was less effective in inhibiting TNFα-induced apoptosis than Z-VAD-FMK or Z-VEID-FMK, presumably because caspase 6 is only one of at least three effector caspases, the others being caspase 3 and 7, that are active during caspase dependent apoptosis. Loss of DNA-binding activity and TNFα-induced apoptosis can be prevented by caspase-6-preferred inhibitor (Z-VEID-FMK)1.

The caspase-6-specific inhibitor Z-VEID- FMK and general caspase inhibitors significantly prevent apoptosis of caspase-6-microinjected neurons2.

Z-VEID-FMK, which inhibits caspase-6, was also able to abolish the cleavage of procaspase-8, although caspase-6 is activated downstream of caspase-8 in Fas-mediated apoptosis3.
