Description: SB269652 is the first drug-like allosteric modulator of the dopamine D2 receptor (D2R). SB269652  binds in a bitopic manner at one protomer of a D2R dimer and modulates the binding of dopamine at a second protomer. Dr. Roberto Maggio's group at University of L'Aquila first domonstrated the allosteric nature of SB269652. This drug 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.
