Design, synthesis, and evaluation of N-(4-(4-phenyl piperazin-1-yl)butyl)-4-(thiophen-3-yl)benzamides as selective dopamine D3 receptor ligands
As part of our on-going effort to explore the role of dopamine receptors in drug addiction and identify potential novel therapies for this condition, we have a identified a series of N-(4-(4-phenyl piperazin-1-yl)butyl)-4-(thiophen-3-yl)benzamide D3 ligands. Members of this class are highly selective for D3 versus D2, and we have identified two compounds (13g and 13r) whose rat in vivo IV pharmacokinetic properties that indicate that they are suitable for assessment in in vivo efficacy models of substance use disorders.

Design, synthesis, and binding affinities of potential positron emission tomography (PET) ligands with optimal lipophilicity for brain imaging of the dopamine D3 receptor. Part II
In the search for compounds with potential for development as positron emission tomography radioligands for brain D3 receptor imaging, a series of N-[4-(4-arylpiperazin-1-yl)butyl]arylcarboxamides with appropriate lipophilicity (2 3 receptor affinities but lacked selectivity over D2 receptors.
