Descrição

Descrição geral

stable for several months at 4°C. Stock solutions (10 mM in methanol or ethanol) are stable for several months at 4°C.

Aplicação

Irreversible inhibitor of certain serine proteases; used to inhibit chymotrypsin in preparations of trypsin.

N-p-Tosyl-L-phenylalanine chloromethyl ketone has been used:

• to investigate whether transcription factor NFκB is involved in renalase expression
• to test the role of NF-κB activation
• to study its inhibitory effect on chymotrypsin

Ações bioquímicas/fisiológicas

Blocks the LPS- or cytokine-induced activation of nuclear factor κB (NFκB), which, in turn, blocks the induction of iNOS and COX-2 transcription. Blocks activation of pp70^s6k by all mitogens. Blocks apoptosis cell lines by inhibiting the processing of caspases in some cell lines and to some stimuli. Also blocks apoptosis initiated by Taxol (in MCF-7 human breast carcinoma cells).

N-p-Tosyl-L-phenylalanine chloromethyl ketone (TPCK) blocks the lipopolysaccharide (LPS)- or cytokine-induced activation of nuclear factor κB (NFκB), which, in turn, blocks the induction of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) transcription. Blocks activation of pp70s6k by all mitogens. Blocks apoptosis cell lines by inhibiting the processing of caspases in some cell lines and to some stimuli. Also blocks apoptosis initiated by Taxol (in MCF-7 human breast carcinoma cells). TPCK recognises the phenylalanine residue in chymotrypsin′s and prevents its function.

Embalagem
