6-position incorporated into a furan, 1,3-dioxane, oxazole, pyran, morpholine, or 1,4-dioxane ring system. Among these compounds, indeno[5,4-b]furan analogues were found to be the most potent and selective MT(1) receptor ligands and to have superior metabolic stability. The optimization of substituents led to (S)-(-)-22b, which showed very strong affinity for human MT(1) (K(i) = 0.014 nM), but no significant
为了开发一种新的睡眠障碍治疗剂,我们合成了一系列新的三环茚满衍生物,并评估了它们与褪黑激素受体的结合亲和力。在我们以前的论文中,我们提出了甲氧基的构型,有利于MT(1)受体的结合。为了将甲氧基固定在一个活性构象中,我们决定合成构象受限的三环茚满类似物,将其在呋喃,1,3-二恶烷,恶唑,吡喃,吗啉或1,4-中的6-位氧原子合成二恶烷环系统。在这些化合物中,茚并[5,4-b]呋喃类似物被发现是最有效和最具选择性的MT(1)受体配体,并具有出色的代谢稳定性。取代基的优化导致(S)-(-)-22b,它对人MT(1)的亲和力非常强(K(i)= 0.014 nM),但对仓鼠MT(3)()(K(i)= 2600 nM)或其他神经递质受体无明显亲和力。在实验动物中研究了(S)-(-)-22b的药理作用,发现以0.1 mg / kg的剂量po可以促进自由活动的猫的睡眠,如清醒性的降低和增加所表明的在慢波睡眠
