CA-074 ME Structural

What is CA-074 ME?

The Uses of CA-074 ME

CA-074 methyl ester is a cell-permeable cathepsin B inhibitor.

The Uses of CA-074 ME

CA-074 methyl ester has been used as cathepsin B inhibitor in cardiomyocytes, HeLa cells and human pancreatic cancer PANC-1 cells.

What are the applications of Application

CA-074 methyl ester is a cell-permeable cathepsin B inhibitor

Biological Activity

ca-074 me is a membrane-permeable and selective inhibitor of cathepsin b with ic50 value of 36.3 nm [1, 2].ca-074 me is a methyl ester derivative of ca-074. in cultured human gingival fibroblasts, ca-074 me exerted a 95% inhibition of cathepsin b and partial inhibition (54%) of the combined activities of cathepsins b and l. ca-074 me was also found to inhibit cathespin l under reducing conditions. it inhibited the activity of purified human cathepsin l by more than 90% when the enzyme had been pre-incubated with 1.4 mm dtt or 4.2 mm gsh for 2 hours. besides that, ca-074 me completely inhibited cathepsin b in the presence of 1.4 mm dtt [2, 3].

Biochem/physiol Actions

CA-074 methyl ester is a cell-permeable analog of CA-074. It is an inhibitor of cathepsin B especially the intracellular type. and undergoes intracellular transition into active CA-074 by the action of esterases. CA-074 methyl ester also inhibits cathepsin L.
