Design and synthesis of some new 1-phenyl-3/4-[4-(aryl/heteroaryl/alkyl-piperazine1-yl)-phenyl-ureas as potent anticonvulsant and antidepressant agents
A series of 1-phenyl-3/4-[4-(aryl/heteroaryl/alkyl-piperazine1-yl)-phenyl-urea derivatives (29–42) were designed, synthesized and evaluated for their anticonvulsant activity by using maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) seizure tests. The acute neurotoxicity was checked by rotarod assay. Most of the test compounds were found effective in both seizure tests. Compound 30
设计、合成了一系列 1-苯基-3/4-[4-(芳基/杂芳基/烷基-哌嗪1-基)-苯基-脲衍生物(29-42),并通过使用最大电休克来评估其抗惊厥活性( MES)、皮下戊四唑 (scPTZ) 癫痫试验。通过旋转棒试验检查急性神经毒性。发现大多数测试化合物在两种癫痫发作测试中都是有效的。化合物 30(1-4-[4-(4-氯-苯基)-哌嗪-1-基]-苯基}-3-苯基-脲)在 MES 和 scPTZ 测试中表现出显着的抗惊厥活性。化合物 30 的 II 期抗惊厥定量研究表明,对 MES 诱发的癫痫发作的 ED50 值为 28.5 mg/kg。此外,该化合物还对毛果芸香碱诱导的大鼠癫痫持续状态显示出相当大的保护作用。由 3-巯基丙酸模型和氨基硫脲诱导的癫痫发作被化合物 30 显着减弱,这表明其具有广谱的抗惊厥活性。有趣的是,化合物 30 显示出比标准药物氟西汀更好的抗抑郁活性。此外,化合物 30 在亚急性毒性研究中表现为无毒化学实体。

against different fungal species. The biological results show that the most active compounds possess an antifungal activity comparable or higher than Fluconazole against Candida albicans, non-albicans Candida species, Cryptococcus neoformans and dermathophytes. Because of their racemic nature, the most active compounds 5f and 6c were tested as pure enantiomers. For 6c the (R)-enantiomer resulted more

IC50 in range 2.3–20 µM and selectivity towards acetylcholinesterase, while being inactive towards butyrylcholinesterase. Structure-activity relationship analysis revealed the influence of N,N-diarylpiperazine moiety and the linker connecting two pharmacophores on the inhibitory activity. Kineticstudies on the two most active compounds 7g and 8g (IC50 = 2.3 and 4 µM, respectively) revealed mixed type

seizure tests. Further, neurotoxicity evaluation was carried out using rotarod method. Structure activity relationship studies showed that compounds possessing aromatic group at the piperazine ring displayed potent anticonvulsant activity. Majority of the compounds showed anti-MES activity whereas compounds 39, 41, 42, 43, 44, 50, 52, and 53 exhibited anticonvulsant activity in both seizure tests. All the
