Caspase-3/7 Inhibitor I
Caspase-3/7 inbibitor I is a potent, reversible, isatin sulfonamide-based inhibitor of caspase-3 (KI(app) = 60 nM) and caspase-7 (KI(app) = 170 nM). Is a weaker inhibitor of caspase-9 (Ki(app) = 3.1 mM). It Has only a trivial effect (Ki(app) >25 mM) on the activities of caspase-1, caspase-2, caspase-4, caspase-6, and caspase-8. It has been shown to inhibit apoptosis in camptothecin treated Jurkat cells (IC50 ~50 µM). Also it has been reported to inhibit apoptosis in chondrocytes (44% inhibition at 10 µM and 98% inhibition at 50 µM). Selectivity for caspases-3 and 7 involves unique hydrophobic residues in the S2 pocket surrounding the catalytic cysteine residue. [1] [2] In some systems inhibition of caspases-3 and -7 can prevent apoptosis and may therefore have important therapeutic implications. [3]
A potent, cell-permeable, and specific, reversible inhibitor of caspase-3 (Ki = 60 nM) and caspase-7 (Ki = 170 nM).

Cell lines |
Human Jurkat T 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. |

Reaction Conditions |
50 μM |
|
Applications |
Cells were treated with camptothecin to induce cell death, and the ability of the compound to inhibit cell death was assessed by FACS analysis. A good correlation exists between relative cell-based activities of the compound with its in vitro isolated caspase 3 or 7 inhibition activites. The compound exhibited 54% inhibition of apoptosis at 50 μM and 22% at 10 μM. |
