Application

MDL 28170 has been used as a calpain inhibitor:
  • to study its effects on neuroinflammation and necroptosis in rat model of cardiac arrest
  • to analyze its effects on the degradation of neuronal nitric oxide synthase (nNOS) in beef semimembranosus muscle
  • to study its protective effects against traumatic brain injury and survival of bone marrow-derived mesenchymal stem cells (BMSCs) in rat brain

Biochem/physiol Actions

MDL 28170 exhibits neuroprotective effects against spinal cord injury, focal cerebral ischemia, and neonatal hypoxia-ischemia in rats. It also shows anti-inflammatory and anti-neurodegenerative properties. MDL 28170 crosses the blood-brain barrier and penetrates readily through the cell membranes.
MDL 28170 is a potent cell permeable calpain I and II inhibitor; reduces capsaicin-mediated cell death in cultured dorsal root ganglion neurons. Reduced occurrence of apoptosis in H2O2 and A23187 treated PC12 cells. γ-secretase-inhibitor.

Memory consolidation has been suggested to be protein synthesis dependent. Previous data indicate that BDNF-induced dendritic protein synthesis is a key event in memory formation through activation of the mammalian target of rapamycin (mTOR) pathway. BDNF also activates calpain, a

Studies have shown that transplantation of bone marrow-derived mesenchymal stem cells (BMSCs) protects against brain damage. However, the low survival number of transplanted BMSCs remains a pertinent challenge and can be attributed to the unfavorable microenvironment of the injured brain.

Cerebral ischemia-reperfusion injury (CIRI) is the leading cause of poor neurological prognosis after cardiopulmonary resuscitation (CPR).

Matrix metalloproteinase (MMP)-2 is a zinc-dependent endopeptidase which, alongside its known extracellular actions, plays fundamental roles in oxidative stress-induced injury to the heart. Intracellular cleavage targets of MMP-2 selectively mediating this injury include the sarcomeric proteins troponin I, myosin light

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.
