have been synthesized. Several selective AT2 receptor ligands were identified, among those a tert-butylimidazole derivative (20) with a Ki of 9.3 nM, that demonstrates a high stability in human liver microsomes (t½ = 62 min) and in human hepatocytes (t½= 194 min). This methyloxycarbonylthiophene sulfonamide is a 20-fold more potent binder to the AT2 receptor and is considerably more stable in human liver
已经合成了一系列间位取代的苯乙酮衍生物,包括N -(烷氧基羰基)噻吩磺酰胺片段。鉴定了几种选择性 AT2 受体配体,其中K i为 9.3 nM的叔丁基咪唑衍生物 ( 20 )在人肝微粒体 (t ½ = 62 分钟) 和人肝细胞 (t ½ = 194 分钟)。这种甲氧羰基噻吩磺酰胺是 AT2 受体结合剂的 20 倍,并且在人肝微粒体中的稳定性比先前报道和广泛研究的结构相关的 AT 2 R 原型拮抗剂3强得多(C38)。配体20作为 AT2R 激动剂并引起 AT2R 介导的预收缩小鼠主动脉的浓度依赖性血管舒张。此外,与咪唑衍生物 C38 相比,叔丁基咪唑衍生物20是 CYP3A4、CYP2D6 和 CYP2C9 的弱抑制剂。本文证明,较小的烷氧基羰基使这一系列AT2选择性化合物中的配体更不易降解,并且在烷氧基羰基截断后可以保持高AT2受体亲和力。通过对接计算结合分子动力学模拟探索了最有效的 AT
