General description
A cell-permeable inhibitor of caspase-1 (ICE; Interleukin-1β Converting Enzyme), caspase-4, and caspase-5. The C-terminal YVAD-CHO sequence of this peptide is a highly specific, potent, and reversible inhibitor of caspase-1 (Ki = 1 nM). The N-terminal sequence (amino acid residues 1-16) corresponds to the hydrophobic region (h-region) of the signal peptide of the Kaposi fibroblast growth factor (K-FGF) and confers cell-permeability to the peptide.

An elevation in inorganic phosphate (P(i)) concentration activates epiphyseal chondrocyte apoptosis. To determine the mechanism of apoptosis, tibial chondrocytes were treated with P(i), and nitrate/nitrite (NO/NO) levels were determined. P(i) induced a threefold increase in the NO/NO concentration; inhibitors of
