Brain-penetrant class I ampakine with AMPA receptor (AMPAR; iGluR) positive allosteric modulator (PAM) activity both in vitro and in vivo.
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.).

Homomeric AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid)-type glutamate receptors (GluRs) were stably expressed in kidney cells from cDNAs encoding GluR1 flop, GluR2 flip, GluR2 flop, and GluR3 flop subunits. The recombinant receptors were of the expected size and showed functional properties in whole-cell

This study investigated whether positive modulators of AMPA-type glutamate receptors influence neurotrophin expression by forebrain neurons. Treatments with the ampakine CX614 markedly and reversibly increased brain-derived neurotrophic factor (BDNF) mRNA and protein levels in cultured rat entorhinal/hippocampal slices. Acute effects

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

Among neurobiological mechanisms underlying antidepressant properties of ketamine, structural remodeling of prefrontal and hippocampal neurons has been proposed as critical. The suggested mechanism involves downstream activation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, which trigger mammalian target of rapamycin (mTOR)-dependent structural plasticity

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.
