element for tuning P‐gp inhibitory activity. In this study, we designed new structurally simplified trimethoxy benzamides (5–17, Table 1) with the aim to uncover the minimal molecular requirements needed for P‐gp inhibition. The new prepared smaller‐sized compounds exhibited IC50 in the low micromolar range. The combined use of NMR and DFT studies suggested that molecular flatness is causatively related
在最近对三甲氧基苯甲酰肼的研究中,我们发现分子内氢键的形成是调节P-gp抑制活性的关键因素。在这项研究中,我们设计了新的结构简化的三甲氧基苯甲酰胺(5 – 17,表1),旨在揭示抑制P-gp所需的最低分子要求。新制备的小尺寸化合物显示出IC 50在低摩尔浓度范围内。NMR和DFT研究的结合使用表明,分子平面度与P-gp抑制有因果关系。我们的结果清楚地指出,本文提出的协调的理论和实验方法可能对解决偏向P-gp蛋白的结构简化且高效的化合物的设计很有帮助。
