    Functionalized quinazolinone derivatives 1–30 were synthesized by two-step reaction. First, anthranilic acid was treated with substituted phenyl isothiocyanate to synthesize 3-aryl-2-thioxo-2,3-dihydroquinazolinone derivatives 1–8 which in turn reacted with different bromoacetophenone derivatives to obtain fully functionalized quinazolinone derivatives 9–30. Both reactions were catalyzed by triethylamine. All the products were characterized by EI-, HREI-MS, 1H-, and 13CNMR spectroscopic techniques. All compounds were subjected to their in vitro α-glucosidase inhibitory activity. Results showed that except compound 1–3, 5, 7, and 22, all compounds were found potent and showed many folds increased α-glucosidase enzyme inhibition as compared to standard acarbose (IC50 = 750.0 ± 10.0 µM). Compound 13 (IC50 = 85.0 ± 0.5 µM) was recognized as the most potent analog of the whole series, with ninefold enhanced inhibitory potential than the standard acarbose. Compounds 1–9, 11, 12, 22, and 26 were structurally known compounds, while remaining all are new. Kinetic study on compound 13 showed that the compound is following a competitive-type inhibition mechanism. Furthermore, in silico studies have also been performed to better rationalize the interactions between synthetic compound and active site of the enzyme.
    通过两步反应合成了功能化的喹唑啉酮衍生物1-30。首先,用取代的苯基异硫氰酸酯处理邻氨基苯甲酸,合成3-芳基-2-硫代-2,3-二氢喹唑啉酮衍生物1-8,然后这些衍生物与不同的溴乙酰苯衍生物反应,得到完全功能化的喹唑啉酮衍生物9-30。两种反应都由三乙胺催化。所有产物都通过EI-、HREI-MS、1H-和13CNMR光谱技术进行表征。所有化合物都进行了体外α-葡萄糖苷酶抑制活性测试。结果显示,除了化合物1-3、5、7和22外,所有化合物都表现出较强的活性,并且相比于标准药物阿卡波糖(IC50 = 750.0 ± 10.0 µM),它们的α-葡萄糖苷酶酶抑制作用提高了许多倍。化合物13(IC50 = 85.0 ± 0.5 µM)被认为是整个系列中最强的类似物,其抑制潜力比标准阿卡波糖提高了九倍。化合物1-9、11、12、22和26是已知结构的化合物,其余所有都是新化合物。对化合物13的动力学研究表明,该化合物遵循竞争性抑制机制。此外,还进行了计算机模拟研究,以更好地合理化合成化合物与酶活性位点之间的相互作用。

    A novel methodology is presented for the synthesis of 3‐substituted 2‐thioxo‐2,3‐dihydroquinazolin‐4(1H)‐one derivatives based on an efficient tandem multicomponent reaction using copper bromide as catalyst. This methodology is based on the multicomponent one‐pot reaction of methyl 2‐bromobenzoate, phenylisothiocyanate derivatives and sodium azide in the presence of copper bromide and l‐proline under
    提出了一种新的方法,该方法基于使用溴化铜作为催化剂的高效串联多组分反应,可以合成3-取代的2-thioxo-2,3-二氢喹唑啉-4(1 H)-one衍生物。该方法基于在碱性条件下,在溴化铜和l-脯氨酸存在下,2-溴苯甲酸甲酯,苯基异硫氰酸酯衍生物和叠氮化钠的多组分一锅反应。为了显示该方法的通用性,使用了各种带有给电子或吸电子功能的苯基异硫氰酸酯,并以高分离产率获得了所需的产物。

    日期:——
    A small library of new azomethine derivatives of 3-aryl-2-thioxo-2,3-dihydroquinazolin-4(1H)-ones was synthesized. The key intermediates 2-thioxo-quinazolinones (3a--e), obtained in 2 steps from the corresponding anilines, were treated with methyl chloroacetate to afford S-substituted esters (4a,d), which were then converted into corresponding acetohydrazides (5a,d). Further, acetohydrazide (5d) was converted to the azomethines derivatives (6a--k) by reacting with a number of suitably substituted benzaldehydes. FTIR, ^1H NMR, ^13}C NMR, GC-MS, and elemental analyses were used to confirm the assigned structures of the synthesized compounds. Further, compounds 3a, 5, and 6j were also confirmed by X-ray diffraction data.
