    名称:
    Design and synthesis of 4-amino-2-phenylquinazolines as novel topoisomerase I inhibitors with molecular modeling
    摘要:
    4-Amino-2-phenylquinazolines 7 were designed as bioisosteres of 3-arylisoquinolinamines 6 that were energy minimized to provide stable conformers. Interestingly, the 2-phenyl ring of 4-amino-2-phenylquinazolines was parallel to the quinazoline ring and improved their DNA intercalation ability in the DNA-topo I complex. Among the synthesized 4-amino group-substituted analogs, 4-cyclohexylamino-2-phenylquinazoline 7h exhibited potent topo I inhibitory activity and strong cytotoxicity. Interestingly, consistency was observed between the cytotoxicities and topo I activities in these quinazoline analogs, suggesting that the target of 4-amino-2-phenylquinazolines is limited to topo I. Molecular docking studies were performed with the Surflex-Dock program to afford the ideal interaction mode of the compound into the binding site of the DNA-topo I complex in order to clarify the topo I activity of 7h.

    喹唑啉衍生物作为有效抗克鲁氏锥虫药物的合成,2D-QSAR研究和生物学评价
    摘要:
    背景:恰加斯病感染了全世界约700万人。目前只有两种药物可用于治疗这种寄生虫病,即苯并尼达唑(Bzn)和硝呋替莫(Nfx)。两种药物在该疾病的慢性期均具有有限的疗效。因此,持续的研究是迫切需要以发现新颖的治疗选择。 目的:开发更安全,更有效的治疗性抗-T。Cruzi药物仍然是锥虫杀伤性化疗的主要目标。 方法:研究了一组喹唑啉酮和喹唑啉衍生物作为锥虫杀螨剂的合成,2D-QSAR和类药物理化性质。体外针对克氏锥虫(图拉胡恩(Tulahuen)菌株,Tul 2原种)的表鞭毛纲动物和血流类锥鞭毛纲动物筛选了所有化合物。 结果:在合成和测试的34种化合物中,有6种化合物(5a,5b,9b,9h,13f和13p)对前鞭毛体和三鞭毛体均显示出显着活性,而对Vero细胞无毒性。 结论:这些喹唑啉酮和喹唑啉衍生物的抗原生动物活性代表了针对旨在开发查加斯病的新型化学疗法的药物化学程序的有趣起点。

    to the efficient and completely regioselective generation of aromatic CC and CN bonds. The method is simple, rapid, general and inexpensive, and can be performed without the use of dried solvents. Most of the synthetized compounds are new and in many cases the work‐up required only filtration. Furthermore, this is the first example of the use of a Lewis acid as a catalyst for heteroarylation, vinylation
    在催化量的三氯化铟的存在下,对一系列卤化的氮杂环和不同种类的亲核试剂进行聚焦微波辐照可有效且完全区域选择性地生成芳族CC和CN键。该方法简单,快速,通用且廉价,并且可以在不使用干燥溶剂的情况下进行。大多数合成的化合物都是新化合物,在许多情况下,仅需过滤即可进行后处理。此外,这是使用路易斯酸作为催化剂在π缺陷杂环底物上进行杂芳基化,乙烯基化和胺化反应的第一个例子。
