    二烷基氨基取代的卤代噻吩基查尔酮类似物的溶剂变色和分子内电荷转移
    摘要:
    本文中,我们介绍了在两组二烷基氨基取代的卤代噻吩基查耳酮中两个互补的分子内电荷转移(ICT)跃迁的研究。我们证明,虽然第一个(也是更强的)ICT从4-(二烷基氨基)苯基部分到烯酮发生,但第二个ICT包含噻吩基取代基。前者通过吸收光谱和发射光谱中强烈的溶剂化变色证明,这表明当激发到最低激发态时偶极矩会大大增加。后者是一种短距离的ICT工艺,在对高能带进行光激发后得到了证实,并且碘取代基的极化率更高,从而增强了它。借助(TD)-DFT计算和溶剂变色方法,我们量化了这些影响的程度,并为进一步开发基于查尔酮基染料的设计奠定了基础。我们证明了理论计算可以微调这些互补的ICT流程之间的敏感平衡。

    There is provided a composition comprising a compound represented by general formula (I), wherein R l represents a 5-iodothiophen-2-yl group or the like, and R 2 represents a 4-dimethylaminophenyl group or the like. This composition is useful for diagnosis of an amyloid-related disease such as Alzheimer's disease because the compound has high binding specificity to amyloid β protein, high permeability through the blood-brain barrier, and a property of being rapidly eliminated from sites other than senile plaques in the brain.

    01 μm and 13.18, respectively. PAMPA assays for all compounds were carried out in order to evaluate the capacity of the compounds to cross the blood-brain barrier. Moreover, the most potent MAO-B inhibitor, TB5, was found to be nontoxic at 5 and 25 μm, with 95.75 and 84.59 % viability among cells, respectively. Molecular docking simulations were carried out to understand the crucial interactions responsible

  • Structure–activity relationship of chalcones and related derivatives as ligands for detecting of β-amyloid plaques in the brain
    作者:Masahiro Ono、Miyuki Hori、Mamoru Haratake、Takami Tomiyama、Hiroshi Mori、Morio Nakayama

    A series of novel chalcones and their related derivatives were synthesized and evaluated as beta-amyloid imaging probes. In the structure-activity relationship of binding affinities to synthetic A beta(1-42) aggregates, compound 14 displayed the highest binding affinity in vitro. Amyloid plaques in the Alzheimer's model mouse brain were visualized with 14. In biodistribution studies using normal mice, [I-125]14 showed good brain uptake (2.56% ID/g, 2 min postinjection) and rapid washout from the brain (0.21% ID/g, 60 min postinjection). These results suggest that [I-125]14 should be further investigated as a potentially useful P-amyloid imaging probe.
