    结合谷氨酸受体 A2 配体结合域的新型正变构调节剂的热力学表征:结合实验和计算方法揭示驱动力的差异
    摘要:
    离子型谷氨酸受体 GluA2 的正变构调节为认知障碍(例如阿尔茨海默病)提供了潜在的治疗方法。在本研究中,我们描述了一系列单氟取代的 3,4-二氢-2 H -1,2,4-苯并噻二嗪 1,1-二氧化物的合成、药理学和热力学研究。通过等温滴定量热法 (ITC) 对配体结合的测量表明,GluA2 LBD 处的调节剂系列具有相似的结合亲和力,但热力学驱动力存在差异。结合图5c(7-F)和6(无-F)是焓驱动的,图5A(5-F)和图5b(6-F)的熵驱动。对于5D(8-F),两个数量的大小相等。热力学积分 (TI) 和一步扰动 (OSP) 用于计算调节剂的相对结合亲和力。OSP 计算具有比 TI 更高的预测能力,并且结合较短的总仿真时间,我们发现 OSP 方法对于此设置更有效。此外,从分子动力学模拟中,我们提取了焓和熵,以及 ITC 数据,这表明结合自由能的差异在很大程度上是由直接配体周围的焓解释的。此外,

  • Synthesis, Pharmacological and Structural Characterization, and Thermodynamic Aspects of GluA2-Positive Allosteric Modulators with a 3,4-Dihydro-2<i>H</i>-1,2,4-benzothiadiazine 1,1-Dioxide Scaffold

    Positive allosteric modulators of ionotropic glutamate receptors are potential compounds for treatment of cognitive disorders, e.g., Alzheimer's disease. The modulators bind within the dimer interface of the ligand-binding domain (LBD) and stabilize the agonist-bound conformation, thereby slowing receptor desensitization and/or deactivation. Here we describe the synthesis and pharmacological testing at GluA2 of a new generation of 3,4-dihydro-2H-1,2,4-benzothiadiazine 1,1-dioxides. The most potent modulator 3 in complex with GluA2-LBD-L483Y-N754S was subjected to structural analysis by X-ray crystallography, and the thermodynamics of binding was studied by isothermal titration calorimetry. Compound 3 binds to GluA2-LBD-L483Y-N754S with a K-d of 0.35 mu M (Delta H = -7.5 kcal/mol and -T Delta S = -1.3 kcal/mol). This is the first time that submicromolar binding affinity has been achieved for this type of positive allosteric modulator. The major structural factor increasing the binding affinity of 3 seems to be interactions between the cyclopropyl group of 3 and the backbone of Phe495 and Met496.

    Methods for modulating the levels of glucagon and blood glucose of a mammal are provided. In the subject methods, a positive allosteric modulator of AMPA/kainate receptors is administered to a host. The subject methods find use in applications where it is desired to increase one or both of the glucagon and blood glucose levels in a mammalian host. The subject methods find use in applications where it is desired to decrease the size, or breadth, of the circadian range of blood glucose levels in a mammalian host. The subject methods also find use in applications where it is desired to decrease the frequency, severity, or occurrence of hypoglycemia in a mammalian host. Finally, the subject method finds use in applications where it is desired to decrease the frequency, severity, or occurrence of nocturnal hypoglycemia in a mammalian host, particularly that which occurs in diabetics as a result of therapy with insulins or insulin analogs or other glucose lowering agents, or combinations of such agents.
