  通过改变芳香族供体基团的碱度来调节过渡金属联吡啶的配合物的性质

  摘要：

  联吡啶（3,7-二氮杂双环[3.3.1]壬烷）是非常刚性和高度组织化的配体，在配位化学领域得到广泛应用，它们的过渡金属配合物的氧化还原电势在高氧氧化反应中很重要。价铁络合物，铜络合物催化的叠氮化和64 Cu铜正电子发射断层显像剂成像。在这里，我们显示了15个四齿联吡啶的铜（II）配合物的氧化还原电势和稳定性常数可以通过取代吡啶环来改变（氧化还原电势在约450 mV以上的变化和复合物稳定性在约10 mV以上的变化）日志单位）。还表明，这些变化可以通过p K a预测。吡啶基团的值以及取代基的哈米特参数，以及基于密度泛函理论的能量分解分析，还可以使人们准确地预测氧化还原电势和随之而来的配合物稳定性。结果表明，主要贡献来自于静电相互作用能，因此吡啶供体基团的部分电荷也与氧化还原电势相关。

  Synthesis and Opioid Receptor Affinity of a Series of 2,4-Diaryl-Substituted 3,7-Diazabicylononanones

  摘要：

  3,7-Diazabicyclo[3.3.1]nonan-9-ones having aryl rings in positions 2 and 4 with systematically varied substituents were synthesized using a double Mannich procedure. Radioligand binding assays were performed to measure the affinity of the compounds to the mu-, delta-, and kappa-opioid receptors. The affinity of all 2,4-diphenyl-substituted 3,7-diazabicyclo[3.3.1]nonan-9-ones to the mu- and delta-receptors was found to be low. In contrast, with exception of the nitro- and cyanophenyl-substituted compounds, most of the diazabicycles showed considerable affinity for the kappa-receptor. In particular, the m-fluoro-, p-methoxy-, and m-hydroxy-substituted compounds have an affinity in the submicromolar range. Due to solubility problems in aqueous media, salts of HZ2 were synthesized. The methiodide shows high kappa-affinity and may, thus, be a promising candidate for development of a peripheral kappa-agonist, e.g. for use in the case of rheumatoid arthritis.

  The 2,4-dipyridine substituted 3,7-dimethyl-3,7-diazabicyclo[3.3.1]nonan-9-one 1,5-diester, HZ2, is characterized by a high analgesic potency. The attempt to form ammonium salts of HZ2 or to N-demethylate position 7 resulted in an unexpected hemiaminal cyclization product 1. The structure was elucidated by an X-ray analysis, the 1H- and 13C-NMR spectra could be fully assigned by means of H,H-COSY, Grad-HSQC-EA and ACCORD-HMBC experiments. The MS spectra of 1 exhibit a ring opening. Interestingly, ESI-MS/MS experiments of HZ2 in aqueous solution showed the formation of a hydrated product. The fragmentation pathways of HZ2 and the hydrated product are rather different indicating the formation of a carboxylate.
