Journal Article
Donthamsetti, P., Gallo, E. F., Buck, D. C., Stahl, E. L., Zhu, Y., Lane, J. R., …Javitch, J. A. (2018). Arrestin recruitment to dopamine D2 receptor mediates locomotion but not incentive motivation. Molecular Psychiatry, 25, 2086–2100. https://doi.org/10.1038/s41380-018-0212-4

The dopamine (DA) D2 receptor (D2R) is an important target for the treatment of neuropsychiatric disorders such as schizophrenia and Parkinson's disease. However, the development of improved therapeutic strategies has been hampered by our incomplete...

SB269652 (1) is a negative allosteric modulator of the dopamine D2 receptor. Herein, we present the design, synthesis, and pharmacological evaluation of "second generation" analogues of 1 whereby subtle modifications to the indole-2-carboxamide motif...

© 2018 The Author(s). Sodiumions (Na+) allosterically modulate the binding of orthosteric agonists and antagonists to many class A G protein-coupled receptors, including the dopamine D 2 receptor (D 2 R). Experimental and computational evidences have... Read More about The action of a negative allosteric modulator at the dopamine D2 receptor is dependent upon sodium ions.

Journal Article
Verma, R. K., Abramyan, A. M., Michino, M., Free, R. B., Sibley, D. R., Javitch, J. A., …Shi, L. (2018). The E2.65A mutation disrupts dynamic binding poses of SB269652 at the dopamine D2 and D3 receptors. PLoS Computational Biology, 14(1), Article e1005948. https://doi.org/10.1371/journal.pcbi.1005948

The dopamine D2 and D3 receptors (D2R and D3R) are important targets for antipsychotics and for the treatment of drug abuse. SB269652, a bitopic ligand that simultaneously binds both the orthosteric binding site (OBS) and a secondary binding pocket (...
