  Synthesis and Anticonvulsant Activity of a New Class of 2-[(Arylalkyl)amino]alkanamide Derivatives

  摘要：

  Although most epilepsies are adequately treated by conventional antiepileptic therapy, there remains an unfulfilled need for safer and more effective anticonvulsant agents. Starting from milacemide, a weak anticonvulsant, and trying to elucidate its mechanism of action, we discovered a structurally novel class of potent and preclinically safe anticonvulsants. Here we report the structure-activity relationship (SAR) study within this series of compounds. Different parts of the structural lead 2-[[4-(3-chlorobenzoxy)benzyl]amino] acetamide (6) were thus varied (Figure 1), and many potent anticonvulsants were found. As an outcome of this study, 57 ((S)-2-[[4-(3-fluorobenzoxy)benzyl]amino]propanamide methanesulfonate, PNU-151774E) emerged as a promising candidate for further development for its potent anticonvulsant activity and outstanding therapeutic indexes (TIs) in different animal tests.

  preferable for expression of potent analgesic activity, and that the free carboxyl group is superior in its analgesic activity to that of the esterified or amidated carboxy group at the C-terminal. In addition, N-methylation of the amide bond at the 4th position contributed to improved analgesic activity. These results indicated that the strong and long-lasting analgesic effect of ADAMB is expressed by

  在研究口服给药后具有有效止痛作用的化合物的开发过程中，基于Nα-ami基-甲酰胺的结构，有74个C端类似物（Nα-d基-Tyr-D-Arg-Phe-X）。合成了Tyr-D-Arg-Phe-MeβAla-OH（ADAMB）。在皮下和口服给药后，通过鼠尾压力测试评估它们的镇痛活性，并详细检查其结构活性关系（SAR）。结果清楚地表明，对于有效的镇痛活性，优选在X位上​​含有侧链β-氨基酸的化合物，并且，游离羧基的镇痛活性优于酯化或酰胺化的羧基。 C端。此外，在第4位的酰胺键的N-甲基化有助于改善止痛活性。这些结果表明，ADAMB的强而持久的镇痛作用由Nα-酰胺化，酰胺键在第4位的N-甲基化和碳链长度（β-Ala）的协同作用来表达。残基在第4位，这是最合适的结构。
