Dopamine D3 receptor antagonists and partial agonists are known to modulate the reinforcing and drug-seeking effects induced by cocaine and other abused substances. By introducing functionality into the butylamide linking chain of the 4-phenylpiperazine class of ligands, improved D3 receptor affinity and selectivity, as well as water solubility, is achieved. A series of linking-chain derivatives are disclosed wherein functionality such as OH or OAc groups have been introduced into the linking chain. In general, these modifications are well tolerated at D3 receptors and achieve high selectivity over D2 and D4 receptors.
