(Z)‐2‐(substituted aryl)‐N‐(3‐oxo‐4‐(substituted carbamothioyl)‐3,4‐dihydro‐2H‐benzo[b][1,4]oxazin‐7‐yl) hydrazine carboxamides (6a–r) was synthesized using 2‐amino‐5‐nitrophenol as a starting material. All the synthesized compounds possessed two hydrogen‐bonding domains and their effect on the activity was studied thereof. The anticonvulsant activity was assessed by the maximal electroshock test (MES), subcutaneous
一系列(Z)-2-(取代芳基)-N-(3-氧代-4-(取代氨基甲硫酰基)-3,4-二氢-2H-苯并[b][1,4]恶嗪-7-基) 肼甲酰胺 (6a – r) 是使用 2-氨基-5-硝基苯酚作为起始原料合成的。所有合成的化合物均具有两个氢键结构域,并对其活性的影响进行了研究。通过最大电休克试验(MES)、皮下戊四唑试验(scPTZ)和腹膜内缩氨基硫脲试验(ipTSC)评估抗惊厥活性。发现化合物(6b、6h、6i 和 6p)是该系列中最有效的,因为它们在 MES 测试中显示出 83-100% 的保护。它们在化学诱导的癫痫试验中也显示出相当大的活性。大多数测试化合物没有神经毒性和肝毒性作用。
