    Synthesis and Evaluation of the Acetylcholinesterase Inhibitory Activities of Some Flavonoids Derived from Naringenin
    摘要:
    阿尔茨海默病(AD)是一种不可逆的神经退行性疾病,严重影响许多老年人。随着人口老龄化,AD已经给许多发达国家的医疗保健系统带来了巨大的社会经济负担。现在非常需要新的治疗方法来阻止或逆转疾病的进展。一种在寻找AD新治疗方法上引起科学家长期关注的研究方法是通过抑制乙酰胆碱酯酶(AChE)来重新建立胆碱能传递。柚皮素是一种具有潜在抑制AChE活性的类黄酮。从柚皮素中可以合成许多其他类黄酮衍生物,如类黄酮和香豆素。本研究采用Williamson方法合成了九种类黄酮衍生物,包括四种类黄酮和五种香豆素。通过Ellman方法评估AChE抑制活性,发现有四种物质(2、4、5和7)具有相对较好的生物活性(IC50 <100μM),这些生物活性比柚皮素更好。分子对接揭示了与催化三联体氨基酸残基Ser200和酶的周围区域的强相互作用对于强烈的AChE抑制效果至关重要。化合物7具有最强的AChE抑制活性(IC50 13.0 ± 1.9μM)。这种物质可以用于进一步的研究。

    Alkyldiazonium ion pairs and deamination. 46. N-nitrososulfamates: sources of carbonium ions in aqueous media and substrates in solid-state decompositions
    摘要:
    Potassium N-nitrososulfamates of benzylamine, 2-phenylethylamine, and cyclohexylamine 2a-c were synthesized and examined as sources of carbonium ions in aqueous media. The nitrososulfamates are crystalline compounds which decompose readily at low pHs (approximately 2) under conditions where the parent amines are relatively stable to nitrous acid. In water solutions they produce the corresponding alcohols, principally, along with small percentages of the corresponding esters of potassium bisulfate. The decomposition of the benzyl analogue 2b in the presence of sodium thiocyanate produced, principally, benzyl alcohol, but also benzyl thiocyanate and benzyl isothiocyanate in a ratio of 4.4/1, indicating a muted role for nucleophilicity in this carbonium ion reaction. In sulfate buffers they decompose by psuedo-first-order kinetics (rate constants are reported). In acetic acid they produce principally the corresponding acetate esters. A reaction mechanism is proposed in which the slow step involves the production of diazohydroxide rather than a direct formation of a carbonium ion. The benzyl analogue 2b is an inhibitor of the enzyme pepsin; it also undergoes a photoelimination reaction on irradiation. The nitrososulfamates are perfectly stable when dry, but they undergo a relatively rapid solid-state decomposition (T1/2 almost-equal-to 2-5 days) when exposed to normal atmospheric humidity; surprisingly, the external appearance of the crystals does not change during the decompositions. The products are, principally, the esters of sulfuric acid and potassium bisulfate.
