Application

E-64d has been used as a lysosomal inhibitor in human acute promyelocytic leukemia NB4 cells[1] and Huh-7 cells.[2] It has also been used as a protease inhibitor in free calcium physiological tyrode solution for perfusion into the isolated heart samples.[3]

Actions biochimiques/physiologiques

E-64d is an epoxysuccinyl peptide and an inhibitor of cysteine protease cathepsin B,[4] calpains 1 and 2.[5] E-64d by its cathepsin B protease inhibition functionality, may serve as a potential drug for treating traumatic brain injury (TBI)[5] and Alzheimer′s disease (AD).[6] It inhibits gametocyte surface antigen resulting in a decreased oocyst production in Plasmodium falciparum.[7]

  3. What is the difference between E-64, E-64c and E-64d?

    1 answer
    1. E-64c is a synthetic analog of E-64.  E-64d is the ethyl ester of E-64c.  E-64c is not cell permeable, but E-64d is cell permeable.  E-64d is hydrolyzed in cell culture to E-64c.

  5. How does the storage temperature relate to shipping conditions?

    1 answer
    1. The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
