Abstract:
Future therapies for diseases associated with altered dopaminergic signaling, including Parkinson’s disease, schizophrenia and drug addiction or drug dependence, may be substantially built on the existence of intramembrane receptor-receptor interactions within receptor mosaics where it is believed that the D2
receptor may operate as the “hub receptor” [1]. In particular, it has been proposed that striatal dopaminergic neurotransmission could be under the control of receptor heteromers containing D2 autoreceptors and non-alpha7 nicotinic acetylcholine
heteroreceptors [2]. In an attempt to investigate the biochemical and functional interactions
between dopaminergic autoreceptors and nAChRs containing the beta2 subunit, we
designed and prepared a group of potential bifunctional derivatives incorporating a D2/D3 agonist moiety and a nicotinic alpha4beta2 antagonist fragment, linked by polymethylene spacers of different length. The new compounds have been biologically characterized for their affinity/specificity/functional profile at the target nACh and D2 receptor subtypes. The synthesis of the designed derivatives and the results of their pharmacological investigation will be presented and discussed.
