Application

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

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.

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.
