Structural Features Important for .sigma.1 Receptor Binding
摘要:
Two problems that have hampered a receptor research are (i) a lack of high-affinity agents and iii) the recent identification Of multiple populations of a receptors (i.e., sigma(1) and sigma(2) sites). Recently, several high-affinity sigma ligands have been identified, and the term superpotent sigma ligands has been coined to describe agents with K-i values of <1 nM. We have previously shown that appropriately N-substituted phenylalkylamines bind at a receptors with high affinity. In the present investigation, we examine the structure-affinity relationships of these phenylalkylamine derivatives for sigma binding and describe some of the first superpotent sigma(1) ligands. A binding model was developed to account for the structural features of the phenylalkylamines that appear to be important for the interaction of these agents with sigma(1) sites.

Diastereomere Aminoacylephedrine lassen sich durch Craig‐Verteilung auftrennen. Das unterschiedliche Verteilungsverhalten dieser Verbindungen beruht auf einer Wechselbeziehung zwischen der Carbonamid‐ und der Hydroxylgruppe, die durch die Konfiguration an den 3 Asymmetriezentren in unterschiedlichem Maße beeinflußt wird.
