which the phenyl rings have been widely changed both on the acidic portion and the basic one of the amide spacer, were synthesised. Their vasorelaxing effects, induced through the activation of BK channels, were also evaluated. Although many compounds exhibited effects which could not be attributed to the activation of BK channels, two derivatives showed a clear profile of BK-activators with vasodilator
大电导钙激活钾(BK)通道参与许多基本细胞功能。一致地,被外源性化合物激活BK通道的能力被认为是潜在治疗多种病理的药效学模式。从这个角度来看,开发新的和选择性的BK开瓶器可以视为一个实际的研究领域。本文报道了新的苯甲酰苯胺类化合物的合成和药理学评价,可用于加深对此类BK活化剂的研究,从而加深了对结构-活性关系的理解。从结构的角度来看,这些苯甲酰苯胺属于BK活化剂的一般类别,显示出常见的药效团模型,该模型由两个通过适当的“间隔基”连接的芳基组成 和几乎强制性的酚羟基的存在 特别地,合成了新的苯甲酰苯胺系列,其中苯环在酸性部分和酰胺间隔基的碱性部分均已广泛改变。还评估了通过激活BK通道诱导的血管舒张作用。尽管许多化合物显示出不能归因于BK通道激活的作用,但两种衍生物显示出具有明显的BK激活剂特征,其血管舒张活性与参考苯并咪唑酮NS1619记录的相当或稍低。进一步的分子建模方法使我们能够获得分子
