  Discovery of 3-arylpropionic acids as potent agonists of sphingosine-1-phosphate receptor-1 (S1P1) with high selectivity against all other known S1P receptor subtypes

  摘要：

  A series of 3-arylpropionic acids were synthesized as S1P(1) receptor agonists. Structure-activity relationship studies on the pendant phenyl ring revealed several structural features offering selectivity of S1P(1) binding against S1P(2-5). These highly selective SIP, agonists induced peripheral blood lymphocyte lowering in mice and one of them was found to be efficacious in a rat skin transplantation model, supporting that S1P(1) agonism is primarily responsible for the immunosuppressive efficacy observed in preclinical animal models.

  酰氧基am巨细胞病毒DNA聚合酶抑制剂的构效关系。

  摘要：

  本文描述了新型的巨细胞病毒DNA聚合酶抑制剂的结构活性关系，该抑制剂具有两个通过酰氧基oxy连接子连接的芳基。对其中末端基团不同的一系列类似物的研究表明，在先导化合物的2,4-二氯苯基周围有非常窄的SAR，但苯并噻唑环的各种替代物均具有活性。其中最引人注目的是化合物78的异恶唑环，与先导化合物相比，其效价提高了30倍。我们还描述了10个类似物的设计，合成和评估，其中酰氧基am连接基被等位基团修饰或替代。结构-活性关系研究确定了接头-NH2基团是关键的药效学元素。从头算分子轨道计算与对空间相互作用能的定性估计相结合，表明酰氧基am连接子的最低能构象具有扩展的平面CAr-C = NOC排列以及同平面或反平面NOCC（Ar'）安排。在三个酰氧基am的晶体结构中仅观察到反平面构象。在这些研究的基础上设计的最有效的连接基修饰化合物是氨基甲酸20 20，在巨细胞病毒DNA聚合酶抑制试验中，氨基甲酸am的含量约为对照酰氧基am
