Several compounds with a 4-aminopiperidine scaffold decorated on both nitrogen atoms by alkyl or acyl moieties containing the structural motifs of verapamil and of flunarizine, as well as those that are more frequent in known N-type calcium channel antagonists, have been synthesized. Antinociceptive activity on the mouse hot-plate test was used to select molecules to be submitted to further studies
已经合成了几种具有4-氨基哌啶骨架的化合物,它们在两个氮原子上都被包含维拉帕米和氟那利嗪的结构基序的烷基或酰基部分修饰,以及在已知的N型钙通道拮抗剂中更常见的那些。使用小鼠热板试验的抗伤害感受活性来选择要进一步研究的分子。在PC12大鼠嗜铬细胞瘤克隆细胞系上对活性化合物进行了体外测试,以评估其对N型钙通道和神经性疼痛大鼠模型的作用。已选择了两种具有N型钙通道拮抗作用且对疼痛和神经性疼痛具有有效作用的化合物(3和18)进行进一步研究。
