  loss of a CS moiety. The yields were close to 90% when the reaction was carried out in the presence of diethyl malonate. This compound was unambiguously identified by X-ray crystallography. Under the same conditions, 2-(methoxycarbonyl)phenyl isothiocyanate gave a quinazolinimine derivative instead which is likely to arise from cyclisation of an intermediate N,N′-diarylthiourea. The mechanism of formation

  2-氰基苯基异硫氰酸酯与乙酸锰（III）在乙酸或乙腈中反应，可得到新的缩聚杂环化合物，得益于两个起始异硫氰酸酯分子的结合而失去了CS部分，从而得到了新的缩合杂环。当反应在丙二酸二乙酯存在下进行时，收率接近90％。通过X射线晶体学清楚地鉴定出该化合物。在相同条件下，2-（甲氧基羰基）苯基异硫氰酸酯代替了喹唑啉亚胺衍生物，该衍生物可能是由中间体N，N'-二芳基硫脲的环化产生的。前一种化合物的形成机理可能涉及N，N的形成′-双（2-氰基苯基）硫脲，然后进行相应的环状亚胺衍生物的重排和自由基串联闭环。半假设计算也支持该假设。

Objective: The development of safer and more efficient therapeutic anti-T. cruzi drugs continues to be a major goal in trypanocidal chemotherapy. Method: Synthesis, 2D-QSAR and drug-like physicochemical properties of a set of quinazolinone and quinazoline derivatives were studied as trypanocidal

  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。
