    Conversion of 2-Thioxo-2,3-dihydroquinazolin-4(1H)-ones to N(3)-Unsubstituted 2-(Het)Arylquinazolin-4(3H)-ones by Copper-Mediated Pd-Catalysed Cross-Coupling Reactions
    摘要:
    With the purpose of searching for new heterocyclic building blocks, a new method to access N(3)-unsubstituted 2-(het)arylquinazolin-4(3H)-ones from 2-thioxo-2,3-dihydroquinazolin-4(1H)-one derivatives was developed. The synthetic protocol was based on the copper-mediated palladium-catalysed cross-coupling reactions of 2-thioxo-2,3-dihydroquinazolin-4(1H)-ones with (het)arylstannanes or their S-benzylated derivatives with (het)arylboronic acids, using CuBr center dot Me2S and CuMeSal as promoters, respectively. A similar transformation was applied for the preparation of 2-aryl[ 1]benzothieno[3,2-d]pyrimidin-4(3H)-ones.

  • 2-((3,5-Dinitrobenzyl)thio)quinazolinones: Potent Antimycobacterial Agents Activated by Deazaflavin (F<sub>420</sub>)-Dependent Nitroreductase (Ddn)

    substituents in positions 2 and 4 of the previously synthesized but yet undisclosed 5-cyano-4-(methylthio)-2-arylpyrimidin-6-ones 4, ring closure, and further optimization led to the identification of the potent antitubercular 2-thio-substituted quinazolinone 26. Structure–activity relationship (SAR) studies indicated a crucial role for both meta-nitro substituents for antitubercular activity, while the introduction
    交换先前合成但尚未公开的 5-cyano-4-(methylthio)-2-arylpyrimidin-6-ones 4 的 2 和4位取代基、闭环和进一步优化导致鉴定出有效的抗结核药物 2-硫代喹唑啉酮26。结构-活性关系(SAR)研究表明,两个间硝基取代基在抗结核活性中发挥着至关重要的作用,而在喹唑啉酮核心上引入极性取代基可以减少牛血清白蛋白(BSA)的结合( 63c,63d)。虽然大多数测试的喹唑啉酮类化合物没有表现出针对 MRC-5 的细胞毒性,但通过 Ames 测试发现最有效的化合物26具有诱变性。该类似物对结核分枝杆菌胸苷酸激酶(3-氰基吡啶酮的靶标,位于当前类似物的基础上)表现出中等的抑制效力,表明本发明的S-取代的硫代喹唑啉酮的全细胞抗分枝杆菌活性可能是由于调节替代或额外目标。观察到受辅因子 F 420生物合成 ( fbiC )、辅因子还原 ( fgd ) 或去氮黄素依赖性硝基还原酶活性

    A new, environmentally benign two-step synthesis of 5H[1,3]-thiazolo[2,3-b]quinazoline-3,5-(2H)-dione and 5H-thiazolo[2,3-b]quinazolin-5-one derivatives has been accomplished stepwise. The substituted 2-aminobenzoic acid upon condensation with thiourea in 1-butyl-3-methylimidazolium bromide at moderate temperature under nitrogen atmosphere yielded 2-thioxo-1H-4-quinazolinones. The resulting intermediate

    Pleuromutilin, a naturally occurring product with moderate antibacterial activity, has a unique structure that has attracted great efforts to modify its scaffold to obtain lead compounds. Herein, we report the synthesis of a series of novel pleuromutilin derivatives with a scaffold of 4(3H)-quinazolinone or its analogues at the C-14 side chain and investigated their in vitro activity against Staphylococcus aureus
    日益增长的抗生素耐药性正在引发医疗保健危机,导致迫切需要新的抗生素来应对严重的医院和社区感染。截短侧耳素是一种具有中等抗菌活性的天然产物,其独特的结构引起了人们对对其支架进行修饰以获得先导化合物的巨大努力。在此,我们报道了一系列在C-14侧链上具有4( 3H )-喹唑啉酮或其类似物支架的新型截短侧耳素衍生物的合成,并研究了它们对金黄色葡萄球菌、表皮葡萄球菌以及革兰氏阴性菌的体外活性。 -阴性细菌(大肠杆菌和沙门氏菌肠亚种。肠白痢)。构效关系(SAR)研究表明,4( 3H )-喹唑啉酮苯环上的取代基对于提高抗菌活性的作用不如取代位置重要,而4(3H)-喹唑啉酮N-3位上的取代基对提高抗菌活性的作用并不重要。 H )-喹唑啉酮对疗效有很大影响。用其他环(吡啶、吡咯、噻吩或环戊基)取代4(3 H )-喹唑啉酮的苯部分也显示出很高的抗菌功效,这意味着苯环对于发挥强大的抗菌性能来说是可有可无的。体外
