  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.

  A highly efficient synthetic protocol for the synthesis of thia‐ and selenaheterocycles has been developed. By employing a MoCl5‐mediated intramolecular dehydrogenative coupling reaction, a broad variety of structural motifs was isolated in yields up to 94 %. The electrophilic key transformation is tolerated by several labile moieties like halides and tertiary alkyl groups. Due to the use of disulfide

  A catalyst composed of [Pd(η(3)-C3H5)Cl]2 and N,N,N',N'-tetra(diphenylphosphinomethyl)pyridine-2,6-diamine (L) was found to be effective for one-pot synthesis of 2-substituted benzo[b]furans from 2-halophenols and alkynes. For 2-bromo-3-hydroxypyridine, the catalyst loading could be as low as 1 ppm and the turnover number (TON) was up to 870,000.

  and (CH2)3 linkers have been synthesized with the view to develop potential antinociceptive drugs. The compounds 14 and 21 showed binding at the μ-opioid receptor (MOR), while the compound 11a exhibited dual affinities at both MOR and κ-opioid receptor (KOR). MAP kinase activation indicated all three compounds have opioid agonistic properties. The presence of a double bond and endo-methylcarboxylate
