Application

Ac-YVAD-cmk has been used:
  • as an inflammasome inhibitor to add to THP-1 cells or PBMC (peripheral blood mononuclear cell) before stimulation
  • as a caspase-1 inhibitor injected to C57BL/6 mice
  • as a caspase-1 inhibitor, administered into mice before and during hematopoietic stem cell transplantation (HSCT) to evaluate its effect on bone marrow inflammatory injury
  • to abolish the histidine-rich protein II (HRPII) effect on transendothelial electrical resistance (TEER)
  • as caspase 1 inhibitor, to treat MCF-7 tumor xenograft mice, to validate the role of inflammasomes activation in tumor growth in vivo condition

Biochem/physiol Actions

Ac-YVAD-cmk is a selective ireversible inhibitor of caspase-1 (interleukin-1β converting enzyme, ICE) with some activity also against caspase-4. Ac-YVAD-cmk is anti-apoptotic and has anti-inflammatory and neuroprotective effects, thought to result from its preventing caspase-1 activation of the proinflammatory cytokine, Interleukin-1β.

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
