    Regioselective Quinazolinone-Directed Ortho Lithiation of Quinazolinoylquinoline:  Practical Synthesis of Naturally Occurring Human DNA Topoisomerase I Poison Luotonin A and Luotonins B and E
    摘要:
    A regioselective quinazolinone-directed ortho lithiation on an adjacent quinoline moiety has been used as a key step for a short, efficient, and practical synthesis of the human DNA topoisomerase I poison luotonin A and luotonins B and E. The quinazolinoylquinoline 5 on treatment with in situ-generated nonnucleophilic mesityllithium furnished the desired dilithiated intermediate 6, which on treatment with formaldehyde followed by Mitsunobu ring closure reaction gave luotonin A (1a) in very good yield. The reaction of dilithiated intermediate 6 with DMF directly furnished luotonin B (1b) in 81% yield. Luotonin B (1b) on methylation with p-TSA/methanol gave luotonin E (1c) in 82% yield.

    摘要:
    P-糖蛋白(P-gp)介导的多药耐药性(MDR)是成功进行癌症化疗的主要障碍。具有喹唑啉骨架的新型P-gp抑制剂12k被认为是最有希望进行深入研究的。12k具有高效力(EC 50 = 57.9±3.5 nM),低细胞毒性,并且在逆转K562 / A02细胞对阿霉素(DOX)的耐药性方面具有很长的活性。12k还增强了具有不同结构的其他MDR相关细胞毒性剂的效力,增加了DOX的积累,阻断了K562 / A02 MDR细胞中P-gp介导的Rh123外排,并抑制了P-gp ATPase活性。但是,12k对CYP3A4活性或P-gp表达没有任何影响。尤其是,12k具有良好的半衰期和口服生物利用度,并且对DOX代谢无影响,从而消除了与体内细胞毒剂血浆浓度升高密切相关的副作用。

    An efficient synthesis of 2-hetarylquinazolin-4(3H)-ones via copper-catalyzed direct aerobic oxidative amination of sp3C–H bonds has been developed. This tandem oxidation–amination–cyclization transformation represents a straightforward protocol to prepare 2-hetaryl-substituted quinazolinones from easily available 2-aminobenzamides and (2-azaaryl)methanes.

    MurA是肽聚糖生物合成必不可少的细胞内细菌酶,因此是抗菌药物发现的重要靶标。我们报告了一系列来自大肠杆菌的MurA的基于喹唑啉酮的抑制剂的合成,计算机模拟研究和广泛的结构-活性关系。3-苯甲氧基苯基喹唑啉酮类化合物在低微摩尔范围内显示出对MurA的抑制作用,最有效的衍生物的IC 50为8 µM(58)。此外,呋喃基取代的喹唑啉酮(38,46)的抗菌活性令人振奋,MIC浓度从1 µg / mL到8 µg / mL,并具有其MurA抑制能力。这些数据代表了开发新型抗菌剂以对抗不断增加的细菌耐药性的重要一步。
