3‐benzothiazol‐2‐yl)amino]‐N‐[5‐substituted‐phenyl‐1,3,4‐thiadiazol‐2‐yl]acetamides were synthesized with a prospective exploration of “lead hopping”, using pharmacophoric elements for in vivo anticonvulsant activity. This yielded three potent candidates (5i, 5t, and 5u) in the preliminary screening employing the maximal electroshock seizure (MES) and the subcutaneous pentylenetetrazole (scPTZ) test
各种2-[(6-取代-1,3-苯并噻唑-2-基)氨基]-N-[5-取代-苯基-1,3,4-噻二唑-2-基]乙酰胺的合成与前瞻性探索“铅跳跃”,使用药效元素进行体内抗惊厥活性。这在使用最大电击癫痫 (MES) 和皮下戊四唑 (scPTZ) 测试的初步筛选中产生了三个有效的候选者(5i、5t 和 5u),显示出最小的神经毒性。他们的定量研究表明,在保护指数方面,MES 测试增加了近 2-10 倍,scPTZ 测试增加了 7-67 倍,这是抗惊厥活性药物发现的关键。
