  Oxadiazoles as Ester Bioisosteric Replacements in Compounds Related to Disoxaril. Antirhinovirus Activity

  摘要：

  A series of 1,2,4-oxadiazoles has been prepared as ester bioisosteres and tested against 15 human rhinovirus serotypes, and the MIC(80), the concentration which inhibits 80% or 12 of the serotypes tested, was determined. Homologation of the alkyl group attached to the oxadiazole ring resulted in a reduction in activity with increased chain length. Introduction of hydrophilic groups in this position rendered the compounds inactive. Increasing the length of the side chain attached to the isoxazole ring resulted in an increase in activity. Replacement of the methyl with alkoxyalkyl substituents retained activity; however, introduction of a hydroxyl group on to the side chain reduced activity. Compound 8a, where both the isoxazole and oxadiazole rings were substituted with methyl groups, was one of the most active compounds in the series. A comparison was made between 8a and the two isomeric oxadiazoles 41 and 46, and an attempt was made to explain the difference in activity by examining electrostatic potential maps and by an energy profiling study. No conclusive results were obtained from these studies.

  新型S1P 1受体激动剂–第1部分：从吡唑到噻吩

  摘要：

  通过旨在鉴定新型S1P 1受体激动剂的高通量筛选活动，吡唑衍生物2成为一种命中结构。药物化学工作不仅着重于提高化合物的效力，而且特别着重于解决其固有的不稳定性问题。这导致了新的双环[3.1.0]己烷稠合噻吩衍生物的发现。鉴定出对S1P 1具有高亲和力和选择性的化合物，可有效减少大鼠的淋巴细胞计数。例如，化合物85在S1P 1和S1P 3上的EC 50值为7和2880 nM。分别在大鼠和狗中具有良好的药代动力学特性，很好地分布在脑组织中，并且有效且剂量依赖性地降低了大鼠的淋巴细胞计数。自发性高血压大鼠口服给药后，S1P 1选择性化合物85仅对动物的苏醒阶段没有表现出对平均动脉压的影响，并且仅影响心率。
