In the present study, a focused combinatorial chemistry approach was applied to merge structural fragments of well-known TRPV1 antagonists with a potent anticonvulsant lead compound, KA-104, that was previously discovered by our group. Consequently, a series of 22 original compounds has been designed, synthesized, and characterized in the in vivo and in vitro assays. The obtained compounds showed robust
在本研究中,应用集中的组合化学方法将众所周知的 TRPV1 拮抗剂的结构片段与我们小组先前发现的强效抗惊厥先导化合物KA-104合并。因此,在体内和体外试验中设计、合成和表征了一系列 22 种原始化合物。获得的化合物在最大电击 (MES) 测试和 6 Hz 癫痫模型(使用 32 和 44 mA 电流强度)中显示出强大的体内抗癫痫活性。最有效的化合物53和60显示出以下药理学特征:ED 50 = 89.7 mg/kg (MES)、ED 50 = 29.9 mg/kg (6 Hz, 32 mA)、ED 50= 68.0 mg/kg (6 Hz, 44 mA), ED 50 = 73.6 mg/kg (MES), ED 50 = 24.6 mg/kg (6 Hz, 32 mA), ED 50 = 56.3 mg/kg (6赫兹,44毫安),分别。此外,53和60对iv PTZ 癫痫发作阈值有效,
