  Higher-Affinity Agonists of 5-HT_1AR Discovered through Tuning the Binding-Site Flexibility

  摘要：

  Discovery of high-affinity and high-selectivity agonists of 5-HT1AR. has become very attractive due to their potential therapeutic effects on multiple 5-HT1AR-related psychological and neurological problems. On the basis of our previously designed lead compound FW01 (K-i = 51.9 nM, denoted as 9a in the present study), we performed large-scale molecular dynamics simulations and molecular docking operations on 5-HT1AR-9a binding. We found the flip-packing events for the headgroup of 9a, and we also found that its tail group could bind flexibly at the agornst-binding site of 5-HT1AR. By finely tuning the flip-packing phenomenon of the 9a headgroup and tuning the binding flexibility of 9a tail group, we virtually designed a series of new 9a derivatives through molecular docking operations and first-principles calculations and predicted that these newly designed 9a derivatives should be higher-affinity agonists of 5-HT1AR. The computational predictions on the new 9a derivatives have been confirmed by our wet-experimental studies as chemical synthesis, binding affinity assays, and agonistic-function assays. The consistency between our computational design and wet-experimental measurements has led to our discovery of higher-affinity agonists of 5-HT1AR, with,similar to 50-fold increase in receptor-binding affinity and similar to 25-fold improvements in agonistic function. In addition, our newly designed 5-HT1AR agonists showed very high selectivity of 5-HT1AR over subtype 5-HT2AR and also over three subtypes of dopamine receptors (D-1, D-2, and D-3).

  新型吲哚烷基哌嗪衍生物作为选择性5-HT1A受体激动剂的设计，合成和结构-活性关系研究。

  摘要：

  5-HT1A受体（5-HT1AR）激动剂已涉及多种中枢神经系统（CNS）疾病的治疗，例如抑郁症和焦虑症等。基于我们先前发现的通过虚拟筛选获得的化合物FW01（Ki = 51±16 nM），通过修饰FW01的酰胺尾基和吲哚基团设计并合成了一系列FW01衍生物。SAR探索发现，酰胺尾基和吲哚基团在确定对多巴胺和5-羟色胺受体亚型的结合亲和力和选择性中起着关键作用。在所有测试的化合物中，9_24的Ki值为5±0.6 nM，对5-HT1AR的选择性很好。[35S]GTPγS分析显示9_24是对5-HT1AR的完全激动剂，EC50值为0.059 nM，显示为266.2和146。对5-HT2A和D3的选择性是4倍。用5-HT1AR-9_24进行了分子动力学模拟和分子对接研究，以揭示其高活性和选择性的机理。最后，提出了5-HT1AR的逐步9_24诱导信号转导机制。

  A series of indolebutylamine derivatives were designed, synthesized, and evaluated as a novel class of selective ligands for the dopamine 3 receptor. The most potent compound 11q binds to dopamine 3 receptor with a Ki value of 124 nm and displays excellent selectivity over the dopamine 1 receptor and dopamine 2 receptor. Investigation based on structural information indicates that site S182 located in extracellular loop 2 may account for high selectivity of compounds. Interaction models of the dopamine 3 receptor‐11q complex and structure‐activity relationships were discussed by integrating all available experimental and computational data with the eventual aim to discover potent and selective ligands to dopamine 3 receptor.

  5-HT1A receptor (5-HT1AR) agonists have been implicated in the treatment of a variety of central nervous system (CNS) diseases such as depression and anxiety, et al. Based on our previously found compound FW01 (Ki = 51 ± 16 nM) obtained by virtual screening, a series of FW01 derivatives were designed and synthesized by the modification of the amide tail group as well as indole headgroup of FW01.
