CALPAIN INHIBITOR III Chemical Properties,Usage,Production

Description

MDL-28170 (88191-84-8) is a potent and selective cell permeable calpain inhibitor. Inhibits oxidative damage-induced apoptosis in PC12 cells and capsaicin-induced apoptosis in dorsal root ganglion neurons.1?It penetrates the blood-brain barrier and inhibits brain cysteine protease activity after systemic administration, ameliorating brain damage in a gerbil model of global ischemia.2?Displays neuroprotective effects in neurotrauma rodent models.3?Calpain I Ki?= 8 nM; Cathepsin B Ki?= 24 nM in isolated enzyme assays. IC50?= 0.3 μM in intact cell assay.4

Uses

MDL 28170 acts as a caplain inhibitor reducing hypoxia in ischemic-retinopathy, and various other neuroprotective effects.

Uses

Inhibits calpain proteolysis

Definition

ChEBI: A dipeptide resulting from the formal condensation of the carboxy group of N-benzyloxycarbonyl-L-valine with the amino group of L-phenylalanine aldehyde. It is a potent cell-permeable inhibitor of calpai I and II, and is also a gamma-secretase inhibitor.

General Description

A potent, cell-permeable inhibitor of calpain I and II (K_i = 8 nM) that also reduces capsaicin-mediated cell death in cultured dorsal root ganglion. Reported to block A23187-induced suppression of neurite outgrowth in isolated hippocampal pyramidal neurons. Exhibits neuroprotective effects against glutamate-induced toxicity.

Biological Activity

Potent, selective inhibitor of calpain and cathepsin B (K i values are 10 and 25 nM respectively) that does not inhibit trypsin-like serine proteases. Rapidly penetrates the blood-brain barrier following systemic administration and displays neuroprotective effects in vivo .

Biochem/physiol Actions

Cell permeable: yes
