  Substituted 4-phenyl-2-aminoimidazoles and 4-phenyl-4,5-dihydro-2-aminoimidazoles as voltage-gated sodium channel modulators

  摘要：

  Voltage-gated sodium channels play an integral part in neurotransmission and their dysfunction is frequently a cause of various neurological disorders. On the basis of the structure of marine alkaloid clathrodin, twenty eight new analogs were designed, synthesized and tested for their ability to block human Na(v)1.3, Na(v)1.4 and Na(v)1.7 channels, as well as for their selectivity against human cardiac isoform Na(v)1.5, using automated patch clamp electrophysiological assay. Several compounds exhibited promising activities on different Na-v channel isoforms in the medium micromolar range and some of the compounds showed also moderate isoform selectivities. The most promising results were obtained for the Na(v)1.3 channel, for which four compounds were found to possess IC50 values lower than 15 mu M. All of the active compounds bind to the open-inactivated states of the channels and therefore act as state-dependent modulators. The obtained results validate the approach of using natural products driven chemistry for drug discovery starting points and represent a good foundation for future design of selective Na-v modulators.

  Previously, we reported aryl 2-aminoimidazole (2-AI) adjuvants that potentiate macrolide antibiotics against A. baumannii. Macrolide antibiotics are typically used to treat infections caused by gram-positive bacteria, but are ineffective against most gram-negative bacteria. We describe a new class of dimeric 2-AIs that are highly active macrolide adjuvants, with lead compounds lowering minimum inhibitory

  美国疾病控制与预防中心 (CDC) 报告称，自 2019 年以来，医院获得性感染增加了 65%。主要致病菌之一是革兰氏阴性菌鲍曼不动杆菌。此前，我们报道了芳基 2-氨基咪唑 (2-AI) 佐剂可增强大环内酯类抗生素对抗鲍曼不动杆菌的作用。大环内酯类抗生素通常用于治疗革兰氏阳性菌引起的感染，但对大多数革兰氏阴性菌无效。我们描述了一类新型二聚体 2-AI，它们是高活性大环内酯佐剂，其先导化合物可将针对鲍曼不动杆菌的最低抑制浓度 (MIC) 降低至或低于革兰氏阳性断点水平。母体二聚体将克拉霉素 (CLR) 对鲍曼不动杆菌5075 的 MIC 从 32 μg/mL 降低至 7.5 μM (3.4 μg/mL) 的 1 μg/mL，随后的结构活性关系 (SAR) 研究发现了几种化合物活动。该先导化合物在 1.5 μM (0.72 μg/mL) 时将 CLR MIC 降低至 2 μg/mL，远远超过母体二聚体和之前的先导芳基
