Previously reported propellane derivative KNT-42 preferred the κ receptor and functioned as a message part in the message-address concept, but its affinity for the κ receptor was not high. To improve affinity, we synthesized five pentacyclic propellane derivatives designed for the purpose of fixing the conformation of KNT-42. The etheno- and ethano-bridged derivatives SYK-347 and SYK-393 exhibited high
先前报道的螺ella衍生物KNT-42首选κ受体,并在消息地址概念中起消息部分的作用,但对κ受体的亲和力不高。为了提高亲和力,我们合成了五种五环丙烷衍生物,旨在固定KNT-42的构象。乙炔和乙桥接的衍生物SYK-347和SYK-393对κ受体表现出高亲和力和选择性,而其他衍生物则没有。这些结果将归因于碱性氮的移动范围不同以及由于引入的羟基或酮基的电子吸收作用而使氮的碱性降低。期望κ受体的SYK-347和SYK-393可用于设计针对阿片样受体类型,特别是κ受体的选择性配体。
