  Discovery of a novel chemotype of potent human ENaC blockers using a bioisostere approach. Part 2: α-Branched quaternary amines

  摘要：

  We report the synthesis and biological evaluation of a series of novel alpha-branched pyrazinoyl quaternary amines for their ability to block ion transport via the epithelial sodium channel (ENaC) in human bronchial epithelial cells (HBECs). Compound 12g has an IC50 of 30 nM and is highly efficacious in the Guinea-pig tracheal potential difference (TPD) model of ENaC blockade with an ED50 of 1 mu g kg(-1) at 1 h. In addition the SAR results demonstrate for the first time the chiral nature of the binding site of human ENaC. As such, pyrazinoyl quaternary amines represent a promising new class of ENaC blockers for the treatment of cystic fibrosis that are structurally distinct from the pyrazinoyl guanidine chemotype found in prototypical ENaC blockers such as amiloride.

  具有手性烷基化咪唑烷环的吡虫啉衍生物的合成及其杀虫活性和对烟碱乙酰胆碱受体的亲和性评估

  摘要：

  不对称合成了一系列具有烷基化咪唑烷环的吡虫啉（IMI）衍生物，以评估其对成年雌性家蝇Musca domestica的杀虫活性以及对果蝇的烟碱乙酰胆碱受体的亲和力。烷基越大，受体亲和力越低，但是在咪唑烷环的R -5-位甲基化和乙基化的衍生物与未取代的化合物等价。受体亲和力的定量结构-活性关系（QSAR）分析表明，将取代基引入咪唑烷环基本上是不利的，但在R处引入取代基如果尺寸较小，则允许-5-位置。合成衍生物与受体的结合模型支持QSAR分析，表明在配体结合位点R -5-位置周围的短烷基存在空间。此外，在杀虫活性和受体亲和力之间观察到正相关，这表明即使修饰了咪唑烷环，受体亲和力也是影响杀虫活性的主要因素。

The bulkier the alkyl group, the lower was the receptor affinity, but the derivatives methylated and ethylated at the R-5-position of the imidazolidine ring were equipotent to the unsubstituted compound.
