  role in its antiepileptic properties. Using this novel molecular target, we initiated a drug-discovery program searching for ligands with significant affinity to LBS with the aim to characterize their therapeutic potential in epilepsy and other central nervous system diseases. We systematically investigated the various positions of the pyrrolidone acetamide scaffold. We found that (i) the carboxamide moiety

  （S）-α-乙基-2-氧代吡咯烷乙酰胺2（左乙拉西坦，Keppra，UCB SA）是吡乙酰胺的结构类似物，最近已被批准作为成人难治性部分发作的附加治疗药物。由于独特的作用机理，该药物似乎具有显着的功效和高耐受性。后者涉及2的脑特异性结合位点（左乙拉西坦结合位点为LBS），可能在其抗癫痫特性中起主要作用。使用这种新型分子靶标，我们启动了一项药物发现计划，以寻找对LBS具有显着亲和力的配体，以表征其在癫痫和其他中枢神经系统疾病中的治疗潜力。我们系统地研究了吡咯烷酮乙酰胺支架的各个位置。我们发现（i）2上的羧酰胺部分对于亲和力是必不可少的；（ii）在100个不同的侧链中，优选的羧酰胺取代α是具有（S）-构型的乙基；（iii）2-氧吡咯烷环优于哌啶类似物或无环化合物；（iv）内酰胺环的3或5位取代降低了LBS亲和力；（v）内酰胺环被小的疏水基团4-取代改善了体外和体内的效力。已显示在4位上取代的6种有趣的候选物在体内比2种更有效。

  N-Acetic acid derivatives (I) of 2-substituted 1, 4-benzoxazines and benzothiazines were designed and synthesized for evaluation as new aldose reductase inhibitors. In general, 3-thioxo derivatives were more potent inhibitors of aldose reductase from human placenta in vitro than the corresponding 3-oxo derivatives. While many compounds (I) were not very effective in inhibiting sorbitol accumulation in the rat sciatic nerve in vivo, the 3-thioxo compounds bearing an isopropyl group at the 2-position showed highly potent activity in the in vivo assay. Compound 46 (AD-5467) was selected from this series as a candidate for further development.

  N-乙酸衍生物（I）的2-取代基1,4-苯并恶嗪和苯并噻嗪被设计合成，以评估其作为新型醛糖还原酶抑制剂的潜力。一般而言，3-硫代羰基衍生物在体外对人胎盘醛糖还原酶的抑制活性比相应的3-氧代衍生物更强。虽然许多化合物（I）在体内对大鼠坐骨神经山梨醇积累的抑制作用并不十分有效，但在体内试验中，2-位带有异丙基的3-硫代羰基化合物显示出极强的活性。从这一系列中选出化合物46（AD-5467）作为进一步开发的候选药物。
