Positive allosteric modulation of metabotropic glutamate receptor 5 (mGluR5) is regarded as a potential novel treatment for schizophrenic patients. Herein we report the synthesis and SAR of 4-aryl piperazine and piperidine amides as potent mGluR5 positive allosteric modulators (PAMs). Several analogs have excellent activity and desired drug-like properties. Compound 2b was further characterized as a PAM using several in vitro experiments, and produced robust activity in several preclinical animal models.

The synthesis, pharmacological evaluation, and structure - activity relationships (SARs) of a series of novel arylalkylpiperazines structurally related to BP897 (3) are described. In binding studies, the new derivatives were tested against a panel of dopamine, serotonin, and noradrenaline receptor subtypes. Focusing mainly on dopamine D3 receptors, SAR studies brought to light a number of structural features required for high receptor affinity and selectivity. Several heteroaromatic systems were explored for their dopamine receptor affinities, and combinations of synthesis, biology, and molecular modeling, were used to identify novel structural leads for the development of potent and selective D3 receptor ligands. Introduction of an indole ring linked to a dichlorophenylpiperazine system provided two of the most potent and selective ligands known to date (D 3 receptor affinity in the picomolar range). The intrinsic pharmacological properties of a subset of potent D3 receptor ligands were also assessed in [35S]-GTPγS binding assays. Evidence from animal studies, in particular, has highlighted the dopaminergic system's role in how environmental stimuli induce drug-seeking behavior. We therefore tested two novel D3 receptor partial agonists and a potent D 3-selective antagonist in vivo for their effect in the cocaine-seeking behavior induced by reintroduction of cocaine-associated stimuli after a long period of abstinence, and without any further cocaine. Compound 5g, a nonselective partial D3 receptor agonist with a pharmacological profile similar to 3, and 5p, a potent and selective D 3 antagonist, reduced the number of active lever presses induced by reintroduction of cocaine-associated stimuli. However, 5q, a highly potent and selective D3 partial agonist, did not have any effect on cocaine-seeking behavior. Although brain uptake studies are needed to establish whether the compounds achieve brain concentrations comparable to those active in vitro on the D3 receptor, our experiments suggest that antagonism at D2 receptors might significantly contribute to the reduction of cocaine craving by partial D3 agonists.
