Cocaine 59-66 glutamate ionotropic receptor AMPA type subunit 1 Rattus norvegicus 184-189 30104957-9 2018 These findings suggest that activated PKG, after repeated exposure to cocaine, binds to AMPA receptor GluA1 and is required for the phosphorylation of S831, contributing to behavioral changes. Cocaine 70-77 glutamate ionotropic receptor AMPA type subunit 1 Rattus norvegicus 102-107 30128074-3 2018 Herein, we describe the discovery, lead optimization, and preclinical characterization of 5-arylbenzimidazolone and oxindole-based negative modulators of AMPARs associated with TARP gamma-8, the primary TARP found in hippocampus. 2-oxindole 116-124 glutamate ionotropic receptor AMPA type subunit 1 Rattus norvegicus 154-160 30128074-4 2018 High-throughput screen lead 4 was optimized for potency and brain penetration to provide benzimidazolone 3, JNJ-55511118.1 Replacement of the benzimidazolone core in 3 with an oxindole mitigated reactive metabolite formation and led to the identification of 18 (GluA1/gamma-8 pIC50 = 9.7). benzimidazolone 89-104 glutamate ionotropic receptor AMPA type subunit 1 Rattus norvegicus 262-267 30128074-4 2018 High-throughput screen lead 4 was optimized for potency and brain penetration to provide benzimidazolone 3, JNJ-55511118.1 Replacement of the benzimidazolone core in 3 with an oxindole mitigated reactive metabolite formation and led to the identification of 18 (GluA1/gamma-8 pIC50 = 9.7). 2-oxindole 176-184 glutamate ionotropic receptor AMPA type subunit 1 Rattus norvegicus 262-267 28948570-6 2018 Since GluN2B, via inhibition of ERK, regulates the membrane expression of GluA1, we measured ERK2 phosphorylation in the crude synaptosomal fraction of these brain regions, which was significantly reduced suggesting that ketamine-induced phosphorylation of alphaCaMKII promotes GluN2B (S1303) phosphorylation that, in turn, inhibits ERK 2 signaling, an effect that results in reduced membrane expression and phosphorylation of GluA1.

Remifentanil 181-193 glutamate ionotropic receptor AMPA type subunit 1 Rattus norvegicus 55-60 28948570-6 2018 Since GluN2B, via inhibition of ERK, regulates the membrane expression of GluA1, we measured ERK2 phosphorylation in the crude synaptosomal fraction of these brain regions, which was significantly reduced suggesting that ketamine-induced phosphorylation of alphaCaMKII promotes GluN2B (S1303) phosphorylation that, in turn, inhibits ERK 2 signaling, an effect that results in reduced membrane expression and phosphorylation of GluA1. Ketamine 221-229 glutamate ionotropic receptor AMPA type subunit 1 Rattus norvegicus 427-432 28948570-7 2018 Taken together, our findings point to alphaCaMKII autophosphorylation as a critical signature of ketamine self-administration providing an intracellular mechanism to explain the different effects caused by alphaCaMKII autophosphorylation on the post-synaptic GluN2B- and GluA1-mediated functions.
