Biochem/physiol Actions

CX614 (BDP-37) is a brain-penetrant class I ampakine (benzoxazine subgroup of benzamide-type) with AMPA receptor (AMPAR; iGluR) positive allosteric modulator (PAM) activity via targeting a binding site shared by cyclothiazide (CTZ), but distinct from that of GYKI 52466. CX614 enhances field excitatory postsynaptic potentials (amplitude & duration) in rat hippocampal slices and autaptically evoked excitatory postsynaptic currents in neuronal cultures (EC50 of 20-40 μM) by blocking desensitization and slowing deactivation of responses to glutamate. CX614 is also widely employed for studying AMPAR-mediated physiological responses in vivo (1-10 mg/kg n rats and mice via i.p.).

The 5-year survival rate of glioblastoma (GBM) is ~10%, demonstrating that a new therapeutic modality for this cancer is desperately needed. Complicating the search for such a modality is that most large molecules cannot pass through the blood brain barrier

Transmembrane AMPA receptor regulatory proteins (TARPs) govern AMPA receptor cell surface expression and distinct physiological properties including agonist affinity, desensitization and deactivation kinetics. The prototypical TARP, STG or γ2 and TARPs γ3, γ4, γ7 and γ8 are all expressed to

Four positive modulators of AMPA-type glutamate receptors (cyclothiazide, CX614, LY404187 and S18986-1) given in acute or chronic manner exerted a neuroprotective effect in lesions induced in postnatal day 5 (P5) mice by intracerebral injection of ibotenate, an NMDA agonist. The

The neural mechanisms that support the late postnatal development of spatial navigation are currently unknown. We investigated this in rats and found that an increase in the duration of AMPAR-mediated synaptic responses in the hippocampus was related to the emergence

Mounting evidence suggests that trophic cell signaling can be mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) activation. It has been demonstrated that exogenous application of brain-derived neurotrophic factor (BDNF) is highly neuroprotective in vitro against neurotoxic insults such as standard chemotherapies.
