  Development of CNS multi-receptor ligands: Modification of known D2 pharmacophores

  摘要：

  Several known D-2 pharmacophores have been explored as templates for identifying ligands with multiple binding affinities at dopamine and serotonin receptors considered as clinically relevant receptors in the treatment of neuropsychiatric diseases. This approach has resulted in the identification of ligands that target multiple CNS receptors while avoiding others associated with deleterious effects. In particular, compounds 11, 15 and 22 may have potential for further development as antipsychotic agents as they favorably interact with the clinically relevant receptors including D2R, 5-HT1AR, and 5-HT7R. We have also identified the pair of compounds 11 and 10 as high affinity D2R ligands with and without SERT binding affinities, respectively. These differential binding profiles endow the pair with the potential for evaluating SERT contributions to antipsychotic drug activity in animal behavioral models. In addition, compound 11 has no significant affinity for 5-HT2CR and binds only moderately to the H1R, suggesting it may not induce weight gain or sedation when used clinically. Taken together, compound 11 displays an interesting pharmacological profile that necessitates the evaluation of its functional and in vivo effects in animal models which are currently ongoing.

  Identification of a new selective dopamine D4 receptor ligand

  摘要：

  The dopamine D-4 receptor has been shown to play key roles in certain CNS pathologies including addiction to cigarette smoking. Thus, selective D-4 ligands may be useful in treating some of these conditions. Previous studies in our laboratory have indicated that the piperazine analog of haloperidol exhibits selective and increased affinity to the DAD(4) receptor subtype, in comparison to its piperidine analog. This led to further exploration of the piperazine moiety to identify new agents that are selective at the D-4 receptor. Compound 27 (KiD4 = 0.84 nM) was the most potent of the compounds tested. However, it only had moderate selectivity for the D-4 receptor. Compound 28 (KiD4 = 3.9 nM) while not as potent, was more discriminatory for the D-4 receptor subtype. In fact, compound 28 has little or no binding affinity to any of the other four DA receptor subtypes. In addition, of the 23 CNS receptors evaluated, only two, 5HT(1A)R and 5HT(2B)R, have binding affinity constants better than 100 nM (K-i < 100 nM). Compound 28 is a potentially useful D-4-selective ligand for probing disease treatments involving the D-4 receptor, such as assisting smoking cessation, reversing cognitive deficits in schizophrenia and treating erectile dysfunction. Thus, further optimization, functional characterization and evaluation in animal models may be warranted. Published by Elsevier Ltd.
