Description	Serine protease inhibitors N-alpha-tosyl-L-lysinyl-chloromethylketone (TLCK) and N-tosyl-L-phenylalaninyl-chloromethylketone (TPCK) exhibit multiple effects on cell death pathways in mammalian cells. Thus, they are able to induce apoptosis by itself or promote cell death induced by other cytotoxic stimuli [King et al., 2004; Murn et al., 2004]. On the other hand, TLCK and TPCK were reported to prevent apoptosis by inhibiting the processing of caspases in response to some cell death inducing stimuli [Stefanis et al., 1997; Jones et al., 1998]. We observed that the pretreatment of HL-60 cells with TLCK or TPCK diminished caspases 3 and -7 (DEVDase) and caspase-6 (VEIDase) activity in response to various cell death inducing stimuli such as staurosporine (STS), etoposide (ETP), or N6-(2-isopentenyl)adenosine. In addition, TLCK but not TPCK inhibited collapse of mitochondrial transmembrane potential Delta Psi m (delta psi) in dying HL-60 cells. Such effects used to be considered as protective, however, the Serine protease inhibitors N-alpha-tosyl-L-lysinyl-chloromethylketone (TLCK) and N-tosyl-L-phenylalaninyl-chloromethylketone (TPCK) exhibit multiple effects on cell death pathways in mammalian cells.
