摘要:
Synthesis and biological evaluation of potent histamine H-3 receptor antagonists incorporating a hydroxyl function are described. Compounds in this series exhibited nanomolar binding affinities for human receptor, illustrating a new possible component for the H-3 pharmacophore. As demonstrated with compound BP1.4160 (cyclohexanol 19), the introduction of an alcohol function counter-intuitively allowed to reach high in vivo efficiency and favorable pharmacokinetic profile with reduced half-life.
