Description

General description

A cell-permeable inhibitor of apoptosis induction (IC₅₀ = 67 µg/ml in FasL-stimulated WC8 cells, 130 µg/ml in etoposide-stimulated U937 cells). Effects attributable to the inhibition of caspase-3 activation but does not directly inhibit caspase-3 even at 1 mg/ml.

A cell-permeable, bis(cyclohexane-1,3-diketone) that is shown to inhibit apoptosis induction in FasL-stimulated WC8 cells (IC₅₀ = 67 µg/ml) and etoposide-stimulated U937 cells (IC₅₀ = 130 µg/ml). The anti-apoptotic effects have been shown to be attributable to inhibition of caspase-3 activation (IC₅₀ = 334 nM), however it does not exhibit any direct inhibition of caspase-3 enzymatic activity. Shown to inhibit the elevation of the liver enzymes, alanine aminotransferase and aspartate aminotransferase, in a murine model of anti-Fas-induced hepatitis. Topical application has been shown to reduce chemotherapy-induced alopecia (hair loss) in newborn rats.
