说明

General description

A cell-permeable, irreversible inhibitor of cysteine proteases. Similar to E-64 (Cat. No. 324890) but devoid of charged groups. Reported to inhibit calpain-1 activation. The inhibitory activity of EST has been attributed to E-64c, the free acid formed by hydrolysis of the ester in vivo. Used in animal models of muscular dystrophy.

Biochem/physiol Actions

Cell permeable: yes

Primary Target
calpain-1

Product does not compete with ATP.

Reversible: no

Target IC₅₀: 10-100 µM for calpain-1

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for 6 months at -20°C.
