  Spectral Characterization of Novel 3-Phenyl-2-Substituted Quinazoline and Fused Quinazoline Derivatives

  摘要：

  3-phenyl-2-thioxo-quinazolin-4(3H)one 1 was utilized for the construction of some novel 2-substituted quinazolin-4(3H)one derivatives through the formation of 2-hydrazinyl quinazolinone, which was used as the key starting material for the synthesis of 2-heteryl quinazolines via the reaction with one carbon donors, -diketones and -ketoester. Infrared, H-1 NMR, and mass spectra of the synthesized compounds were discussed. Some of them showed promising anti-inflammatory activity. Supplemental materials are available for this article.

  A series of 4‐(substituted‐phenyl)‐[1,2,4]triazolo[4,3‐a]quinazolin‐5(4H)‐ones (6a–x) with triazole and other heterocyclic substituents (7–14) were synthesized and the compounds were evaluated for their anticonvulsant activity and neurotoxicity by maximal electroshock (MES) and rotarod neurotoxicity tests. Among the compounds studied, 6o and 6q showed wide margins of safety with protective indices

  一系列具有三唑和其他杂环取代基 (7-14) 的 4-(取代-苯基)-[1,2,4] 三唑并 [4,3-a] 喹唑啉-5(4H)-酮 (6a-x)合成了化合物，并通过最大电休克 (MES) 和旋转棒神经毒性试验评估了化合物的抗惊厥活性和神经毒性。在研究的化合物中，6o 和 6q 显示出广泛的安全范围，其保护指数 (PI) 远高于目前使用的药物（PI6o > 25.5，PI6q > 26.0）。化合物 6o 和 6q 对 MES 诱导的小鼠癫痫发作显示出显着的口服活性，ED50 值分别为 88.02 和 94.6 mg/kg。还发现这两种化合物对由戊四唑和荷包牡丹碱诱发的癫痫发作具有强效活性。
