Description

E4CPG ((RS)-ECPG) is a Group I/Group II metabotropic glutamate receptor (mGluR) antagonist. E4CPG can inhibit the paired-pulse ratio of monosynaptic inhibitory postsynaptic currents (IPSC) potentiation[1][2].

IC50 & Target[1]

mGluR

 

In Vitro

E4CPG acts at rat cortical mGluR with the KB value of 0.367 mM[3].

In Vivo

E4CPG (3-30 nmol/site (i.t.), 1-10 μmol/paw (i.pl.), and 1-10 nmol/site (i.c.v.)) significantly inhibits the nociception induced by the Glutamate-injection (i.pl.; 30 μmol/paw), and the maximal inhibition values for the antinociceptive action of E4CPG in Glutamate-induced nociception are 48% (i.pl.), 49% (i.t.) and 40% (i.c.v.) [4].
E4CPG (35 nM/3.5 μL, i.c.v.) completely blocks long-term depression (LTD) induced by the group I mGluR agonist Dihydroxyphenylglycine (DHPG, 100 nM/5 μL, i.c.v.) in male Sprague-Dawley rats[5].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
