  摘要：

  5-HT（3）受体是开发用于脑，心脏病和癌症疾病的治疗剂以及用于生物医学成像技术PET的成像剂的有吸引力的靶标。苯并恶唑衍生物是一类新型的具有高结合亲和力的5-HT（3）受体部分激动剂。碳11标记的苯并恶唑衍生物已被合成为用于成像5-HT（3）受体的新的潜在PET放射性配体。目标示踪剂是通过使用[（11）C] CH（3）OTf通过其相应前体的N-[（11）C]甲基化制备的，并通过HPLC纯化程序以40-50％的放射化学收率分离，将其衰减校正为基于[（11）C] CO（2）的轰炸（EOB）结束。从EOB开始，总的合成时间为20-25分钟。放射化学纯度> 99％，

  Orally Active Benzoxazole Derivative as 5-HT₃ Receptor Partial Agonist for Treatment of Diarrhea-Predominant Irritable Bowel Syndrome

  摘要：

  During our search for therapeutic agents to treat diarrhea-predominant IBS, we found that 2-substituted benzoxazole derivatives have a characteristic 5-HT3 receptor partial agonist activity with high affinity. Some of these compounds showed high in vitro metabolical. stability, and 6g showed marked antidiarrhetic activity with little side effect of constipation in in vivo tests. Our results indicate that 5-HT3 receptor partial agonists might be superior as therapeutic agents to the drugs currently used for IBS treatment.

  This invention provides a serotonin 5-HT 3 receptor partial activator which has a serotonin 5-HT 3 receptor activating action, in addition to its serotonin 5-HT 3 receptor antagonism, and does not cause constipation as a side effect. Particularly, based on the finding that newly synthesized benzoxazole derivatives typified by the compounds of the following formula (2) have strong serotonin 5-HT 3 receptor antagonism and serotonin 5-HT 3 receptor activating action, this invention provides these benzoxazole derivatives as serotonin 5-HT 3 receptor partial activators. 1 In the above formula, R 1 to R 4 may be the same or different from one another and each represents a hydrogen atom, a halogen atom, a substituted or unsubstituted lower alkyl group, a substituted or unsubstituted lower alkenyl group or a substituted or unsubstituted amino group, or two groups of R 1 and R 2 may be linked together to form a ring structure, namely benzene ring; R 5 represents a hydrogen atom, a substituted or unsubstituted lower alkyl group or a substituted or unsubstituted lower alkenyl group; and m is an integer of 1 to 4.

  本发明提供了一种5-HT3受体部分激动剂，该激动剂具有5-HT3受体激活作用，除了其5-HT3受体拮抗作用外，不会引起便秘等副作用。特别是，基于新合成的苯并咪唑衍生物发现，该衍生物以以下式子（2）的化合物为代表具有强烈的5-HT3受体拮抗作用和5-HT3受体激活作用，本发明提供这些苯并咪唑衍生物作为5-HT3受体部分激动剂。在上述公式中，R1到R4可以相同也可以不同，每个表示氢原子、卤素原子、取代或未取代的低级烷基、取代或未取代的低级烯基或取代或未取代的氨基；或R1和R2的两个基团可以连接在一起形成环结构，即苯环；R5表示氢原子、取代或未取代的低级烷基或取代或未取代的低级烯基；m是1到4的整数。
