  摘要：

  一组新的氮杂双环芳基酰胺已被鉴定为α7nAChR的有效和选择性激动剂。采取了两管齐下的方法来改善先前公开的alpha7 nAChR激动剂PNU-282,987的潜在hERG耐受性，同时保持该化合物的其他所需药理特性。第一种方法涉及对PNU-282,987的芳基羧酸片段的进一步研究，而第二种方法则侧重于对PNU-282,987的氮杂双环胺部分的修饰。每个系列中最好的化合物的特点是脑部快速渗透，在大鼠中具有良好的口服生物利用度，并在大鼠P50听觉感觉门控试验中显示出体内功效。每个系列（1h，1o，2a，9a和18a）中至少有一个类似物表现出比PNU-282,987更高的hERG安全性。

  Inhibitiion of the Na/H exchanger is promising approach for treating ischemia-reperfusion injury, but no clinical agent is yet available. Recently, we established the structural requirements for potent inhibitors of the Na/H exchanger. In the present work, we designed N-(3-oxo-3, 4-dihydro-2H-benzo[1, 4]oxazine-7-carbonyl)guanidine 3a as a new lead compound for potent inhibitors with good water-solubility, based on the previous information. During the structural optimization, care was taken to keep the hydrophobicity (clogP) in the range of about 1.5-2.0, which is considered optimum for good bioavailability. Various derivatives of 3a were synthesized and the quantitative structure-activity relationship (QSAR) was studied. The QSAR result indicated that the lengths of the substituents at the 2- and the 4-positions of the 2H-benzo[1, 4]oxazine ring are parabolically related to activity. The most potent compounds were (R) and/or (S)-N-(2-ethyl-4-isopropyl(or ethyl)-3-oxo-3, 4-dihydro-2H-benzo[1, 4]oxazine-7-carbonyl)guanidines 3q-t with IC50 values of 0.036-0.073 μM. The water-solubility of the hydrochlorides and methanesulfonates is 3-5 mg/ml, which is sufficient for therapeutic use.

  抑制 Na/H 交换机是治疗缺血再灌注损伤的一种很有前景的方法，但目前还没有临床药物。最近，我们确定了 Na/H 交换子强效抑制剂的结构要求。在本研究中，我们根据之前的信息设计出了 N-(3-氧代-3, 4-二氢-2H-苯并[1, 4]恶嗪-7-甲酰基)胍 3a 作为一种具有良好水溶性的强效抑制剂的新先导化合物。在结构优化过程中，我们注意将疏水性（clogP）保持在约 1.5-2.0 的范围内，这被认为是具有良好生物利用度的最佳值。合成了 3a 的各种衍生物，并对其进行了定量结构-活性关系（QSAR）研究。QSAR 结果表明，2H-苯并[1, 4]恶嗪环上 2 位和 4 位取代基的长度与活性呈抛物线关系。最有效的化合物是(R)和/或(S)-N-(2-乙基-4-异丙基（或乙基）-3-氧代-3, 4-二氢-2H-苯并[1, 4]恶嗪-7-甲酰基)胍类 3q-t，IC50 值为 0.036-0.073 μM。盐酸盐和甲磺酸盐的水溶性为 3-5 毫克/毫升，足以用于治疗。
