  调节具有吸电子基团的四氢吡啶-2-胺 BACE1 抑制剂的理化性质：一项系统研究

  摘要：

  药物化学家面临的一个共同挑战是将强碱性基团的共轭酸的 pK a降低到保持所需效果（通常是效力和/或溶解度）的范围内，但避免不希望的效果，例如高分布体积 (V d)、有限的膜渗透和脱靶结合，尤其是 hERG 通道和单胺受体。我们使用含有脒的 3,4,5,6-四氢吡啶-2-胺支架面临这一挑战，脒是 BACE1 潜在抑制剂的关键结构成分，BACE1 是构成淀粉样蛋白斑块的 Aβ 种类产生中的限速酶在阿尔茨海默病中。在我们努力平衡效力与实现大脑穿透的理想特性的过程中，我们在脒的 β 位置引入了一组不同的基团，它们调节 logD、PSA 和 pK a. 鉴于制备这些高度功能化弹头的合成挑战，我们首先开发了一个设计流程，包括预测的物理化学参数，这使我们能够只选择最有希望的合成候选者。为此，我们评估了一组商业软件包来预测物理化学性质，这可以指导药物化学家努力调节脒和胺碱的 pK a值。

  Rational Design of Novel 1,3-Oxazine Based β-Secretase (BACE1) Inhibitors: Incorporation of a Double Bond To Reduce P-gp Efflux Leading to Robust Aβ Reduction in the Brain

  摘要：

  Accumulation of A beta peptides is a hallmark of Alzheimer's disease (AD) and is considered a causal factor in the pathogenesis of AD. beta-Secretase (BACE1) is a key enzyme responsible for producing A beta peptides, and thus agents that inhibit BACE1 should be beneficial for disease-modifying treatment of AD. Here we describe the discovery and optimization of novel oxazine-based BACE1 inhibitors by lowering amidine basicity with the incorporation of a double bond to improve brain penetration. Starting from a 1,3-dihydrooxazine lead 6 identified by a hit-to-lead SAR following HTS, we adopted a pKa lowering strategy to reduce the P-gp efflux and the high hERG potential leading to the discovery of 15 that produced significant A beta reduction with long duration in pharmacodynamic models and exhibited wide safety margins in cardiovascular safety models. This compound improved the brain-to-plasma ratio relative to 6 by reducing P-gp recognition, which was demonstrated by a P-gp knockout mouse model.
