Cannabinoid CB1 and orexin OX1 receptors have been suggested to form heterodimers and oligomers. Aimed at studying these complexes, a series of bivalent CB1 and OX1 ligands combining SR141716 and ACT-078573 pharmacophores were designed, synthesized, and tested for activity against CB1 and OX1 individually and in cell lines that coexpress both receptors. Compound 20 showed a robust enhancement in potency
大麻素 CB1 和食欲素 OX1 受体已被建议形成异二聚体和寡聚体。为了研究这些复合物,设计、合成了一系列结合 SR141716 和 ACT-078573 药效团的二价 CB1 和 OX1 配体,并测试了它们单独和在共表达这两种受体的细胞系中针对 CB1 和 OX1 的活性。与单独表达相比,化合物20在共表达时对两种受体的效力均显着增强,表明可能与 CB1-OX1 二聚体相互作用。靶向 CB1-OX1 受体二聚体的二价配体可作为进一步探索此类异源二聚体在体外和体内作用的工具。
