  白三烯拮抗剂abukastast的合成

  摘要：

  从2，4-二羟基苯乙酮开始，有效地合成了白三烯拮抗剂abukastast（5）。后者在与草酸乙酯的Claisen缩合反应中进行氢化，然后氢化，得到苯二甲酸酯7，使其进行弗里斯重排（AcOH / BF 3 ·OEt 2），然后在与甲醇进行酯交换反应后，将其与5烷基化。 -溴-1-戊基乙酸酯得到乙酸酯9。在氢氧化四正丁基铵存在下用甲醇进行的新型甲醇9甲醇分解反应，然后将衍生的醇进行甲磺酰化，得到甲磺酸酯10。苯乙酮衍生物的烷基化16在三（3,6-二氧杂庚基）胺存在下，使用K 2 CO 3与10进行反应，并进行皂化，得到5。

  23-3544 (7), an antagonist possessing greater potency and duration of action vs LTD4 than the standard (aerosol route of administration, guinea pig bronchoconstriction model). Interestingly, this compound also potently inhibited bronchoconstriction induced by LTB4 whereas 1 did not. Attempts to establish structure--activity relationships in this series involved modifications in the 2-hydroxyacetophenone

  对与标准肽基白三烯拮抗剂FPL 55712（1）中存在的2-羟基苯乙酮药效团相连的一系列3,4-二氢-2H-1-苯并吡喃-2-羧酸的评估导致发现Ro 23-3544（ 7），与LTD4相比，具有比标准品更大的效力和作用持续时间的拮抗剂（气雾剂给药途径，豚鼠支气管收缩模型）。有趣的是，该化合物还有效抑制了LTB4诱导的支气管收缩，而1则没有。试图建立结构-活性关系的尝试涉及对2-羟基苯乙酮部分，连接链和色氨酸系统的修饰。所有变体产生的类似物相对于酸7都是无活性的或具有降低的效能，通过两种方法可实现7的光学拆分。对映体的绝对构型是通过对S对映体的中间体及其盐的X射线晶体学分析确定的。尽管对映异构体在静脉内给药时在体外试验和体内均显示出相似的效力，但通过气雾剂途径给药时，豚鼠支气管收缩模型与LTC4和LTD4相比有显着差异（S肽的效力高15倍）。已经将7的特性与最近报道的几种白三烯拮抗剂进行了比
