  发现一流的肠道限制型RET激酶抑制剂作为IBS治疗的临床候选药物

  摘要：

  腹痛和排便习惯异常是肠易激综合症（IBS）患者治疗不当的主要症状。尽管IBS的病因尚不完全清楚，但胃肠道（GI）的许多功能是由肠神经系统（ENS）调节的。炎症或应激诱导的生长因子或细胞因子的表达可能导致胃肠道内脏传入神经元过度神经支配，并有助于IBS的病理生理。转染（RET）期间重新排列的神经元生长因子受体酪氨酸激酶对ENS的发展至关重要，例如Hirschsprung患者携带RET功能丧失突变且缺乏正常的结肠神经支配导致结肠梗阻。相似地，成人ENS中的RET信号通过促进突触形成，信号传递和神经元可塑性来维持神经元功能。ENS中RET的抑制代表了一种新的神经元功能和IBS患者症状正常化的治疗策略。本文中，我们描述了我们的筛选工作以及随后的结构-活性关系（SAR），以优化该系列的效价，选择性和诱变性，从而发现了首屈一指的肠道限制性RET激酶抑制剂2- （4-（4-乙氧基-6-氧代-1,6-二氢

  2,4-二卤代芳族化合物在S N Ar取代中的邻位选择性。与阴离子亲核试剂的反应

  摘要：

  亲核加成的有机阴离子与卤素的芳族化合物既定位邻位和对位，以活化基团在各种溶剂中进行了研究。在大多数情况下，基材显示出对邻位取代的强烈偏好。提出了激活依赖于基团的配位的证据，这有助于在非极性溶剂中非常高的邻位选择性。这也驱动了这些溶剂中的总反应速率，并且与极性溶剂产生的速率增加幅度几乎相同。帕拉-通过在质子传递溶剂中使用冠醚可最大程度地提高产品的性能。总体而言，溶剂作用与与胺类亲核试剂的相应反应有很大不同，这主要是由于过渡态中存在的电荷不同以及亲核试剂的溶剂化所致。
