Uses
SB269652 is the first drug-like allosteric modulator of the dopamine D2 receptor (D2R); a new chemical probe that can differentiate D2R monomers from dimers or oligomers depending on the observed pharmacology. IC50 value: 0.2/0.5 nM [1] Target: D3 receptor antagonist SB269,652 potently (low nanomolar range) abolished specific binding of [(3)H]nemanopride and [(3)H]spiperone to Chinese hamster ovary-transfected D(3) receptors when radioligands were used at 0.2 and 0.5 nM, respectively. However, even at high concentrations (5 μM), SB269,652 only submaximally inhibited the specific binding of these radioligands when they were employed at 10-fold higher concentrations. By analogy, although SB269,652 potently blocked D(3) receptor-mediated activation of Gα(i3) and phosphorylation of extracellular-signal-regulated kinase (ERK)1/2, when concentrations of dopamine were increased by 10-fold, from 1 μM to 10 μM, SB269,652 only submaximally inhibited dopamine-induced stimulation of Gα(i3) [1].
Biological Activity
SB269652 is an allosteric modulator of D2 dopamine receptors. SB269652 binds to an allosteric site th at is distinct from the orthosteric bound by typical D2 antagonists and is only revealed in D2 receptor dimers. SB269652 is bitopic, binding to an orthosteric site one one partner in the dimer and the allosteric site in the other. Engagement of this secondary pocket at the extracellular end of TM2 and TM7 is a new mechanism of modulating binding of a ligand to the orthosteric site of a second protomer by a G-protein coupled receptor.
