    摘要:
    抽象的 本文重点研究了最近被我们鉴定为逆转录酶(RT)相关的核糖核酸酶H(RNase H)抑制剂的环庚噻吩-3-甲酰胺衍生物的逐步结构修饰。特别地,其向2-芳基-环庚硫基杂氮杂酮衍生物的转化以及对2-芳族和环庚二硫基部分的连续深入探索导致将基于恶嗪酮的化合物鉴定为新的抗RNA酶H化学型。支架C-2位置上邻苯二酚部分的出现对于实现有效的抗RNA酶H活性至关重要,该活性还包括三环衍生物的抗RNA依赖性DNA聚合酶(RDDP)活性。苯并噻吩并恶嗪酮衍生物22产生的最强双重抑制剂表现出IC 50相对于RNase H和RDDP功能的s分别为0.53和2.90μM。诱变和对接研究表明,化合物22结合了RT中的两个变构口袋,一个位于RNase H活性位点和引物结合区之间,另一个位于DNA聚合酶催化中心附近。

    Quinazolinones represent an important scaffold in medicinal chemistry with diverse biological activities. Here, two series of 2-substituted quinazolin-4(3H)-ones were synthesized and evaluated for their antioxidant properties using three different methods, namely DPPH, ABTS and TEACCUPRAC, to obtain key information about the structure–antioxidant activity relationships of a diverse set of substituents
    喹唑啉酮是药物化学中的重要支架,具有多种生物活性。在这里,合成了两个系列的2-取代喹唑啉-4(3 H )-酮,并使用三种不同的方法(即DPPH、ABTS和TEAC CUPRAC )评估了它们的抗氧化性能,以获得有关结构与抗氧化活性关系的关键信息。主要喹唑啉酮支架的位置 2 上有一组不同的取代基。关于抗氧化活性,ABTS 和 TEAC CUPRAC测定比 DPPH 测定更灵敏,结果更可靠。为了获得2-苯基喹唑啉-4( 3H )-酮的抗氧化活性,除了甲氧基取代基或苯环上邻位或对位的第二个羟基之外,还需要存在至少一个羟基。第二系列(化合物25a和25b )中存在喹唑啉酮环和酚取代基之间的额外乙烯连接基,导致抗氧化活性增加。此外,除了抗氧化活性外,苯环邻位上有两个羟基的衍生物还表现出金属螯合性能。我们的研究成功地使用了三种不同的抗氧化活性评估方法,将 2-(2,3-二羟基苯基)喹唑啉-4(3 H

    2-Arylquinazolin-4(3H)-ones 1–25 were synthesized by reacting anthranilamide with various benzaldehydes using CuCl2·2H2O as a catalyst in ethanol under reflux. Synthetic 2-arylquinazolin-4(3H)-ones 1–25 were evaluated for their β-glucuronidase inhibitory potential.

  • Scaffold hopping and optimisation of 3’,4’-dihydroxyphenyl- containing thienopyrimidinones: synthesis of quinazolinone derivatives as novel allosteric inhibitors of HIV-1 reverse transcriptase-associated ribonuclease H
    作者:Graziella Tocco、Francesca Esposito、Pierluigi Caboni、Antonio Laus、John A. Beutler、Jennifer A. Wilson、Angela Corona、Stuart F. J. Le Grice、Enzo Tramontano

    Bioisosteric replacement and scaffold hopping are powerful strategies in drug design useful for rationally modifying a hit compound towards novel lead therapeutic agents. Recently, we reported a series of thienopyrimidinones that compromise dynamics at the p66/p51 HIV-1 reverse transcriptase (RT)-associated Ribonuclease H (RNase H) dimer interface, thereby allosterically interrupting catalysis by altering the active site geometry. Although they exhibited good submicromolar activity, the isosteric replacement of the thiophene ring, a potential toxicophore, is warranted. Thus, in this article, the most active 2-(3,4-dihydroxyphenyl)-5,6-dimethylthieno[2,3-d]pyrimidin-4(3H)-one 1 was selected as the hit scaffold and several isosteric substitutions of the thiophene ring were performed. A novel series of highly active RNase H allosteric quinazolinone inhibitors was thus obtained. To determine their target selectivity, they were tested against RT-associated RNA-dependent DNA polymerase (RDDP) and integrase (IN). Interestingly, none of the compounds were particularly active on (RDDP) but many displayed micromolar to submicromolar activity against IN.
