A series of new 2-phenyl-2H-benzo[e][1,3]oxazin-4(3H)-one derivatives (1a-1t) were designed based on the known anticonvulsant activity of quinolinone derivatives. All target compounds 1a-1t, characterized by IR, 1H NMR and MS, have been evaluated for their anticonvulsant activity against MES-induced seizures. The pharmacological results showed that all the compounds displayed some degree of anticonvulsant activity. Among them, 2-phenyl-2,3-dihydrobenzo[e][1,3]oxazin-4-one (1a) and 2-(2-fluorophenyl)-2,3-dihydrobenzo[e][1,3]oxazin-4-one (1b) were considerd more promising because of their lower ED50 (34.1 and 28.4 mg/kg) and higher protective index (11.1 and 8.0).
基于喹啉酮衍生物已知的抗惊厥活性,设计了一系列新型2-苯基-2H-苯并[e][1,3]恶嗪-4(3H)-酮衍生物(1a-1t)。所有目标化合物 1a-1t 均通过 IR、1H NMR 和 MS 进行表征,并评估了其针对 MES 诱导的癫痫发作的抗惊厥活性。药理学结果表明所有化合物均表现出一定程度的抗惊厥活性。其中,2-苯基-2,3-二氢苯并[e][1,3]恶嗪-4-酮(1a)和2-(2-氟苯基)-2,3-二氢苯并[e][1,3] oxazin-4-one (1b) 被认为更有前景,因为其 ED50 较低(34.1 和 28.4 mg/kg),保护指数较高(11.1 和 8.0)。
