指导早期药物发现的流行策略严重依赖基于平衡的指标,例如亲和力,它忽略了药物分子与其靶标相互作用的动力学过程。在此,我们开发了许多加压素 V 2受体 (V 2 R) 拮抗剂,它们对常染色体显性多囊肾病 (ADPKD) 具有不同的结合亲和力和动力学。令人惊讶的是,V 2 R 拮抗剂的停留时间,但与它们的亲和力无关,与ADPKD 的离体和体内模型中的功效相关。我们设想以动力学为导向的候选药物选择和开发可能对 ADPKD 和其他治疗领域也具有普遍适用性。

Recently, a novel negative allosteric modulator (NAM) of the D2-like dopamine receptors 1 was identified through virtual ligand screening. This ligand comprises a thieno[2,3-d]pyrimidine scaffold that does not feature in known dopaminergic ligands. Herein, we provide pharmacological validation of an allosteric mode of action for 1, revealing that it is a NAM of dopamine efficacy and identify the structural
最近,通过虚拟配体筛选鉴定了D 2样多巴胺受体1的新型负变构调节剂(NAM)。该配体包含在已知的多巴胺能配体中不具有的噻吩并[2,3- d ]嘧啶骨架。在此,我们提供了针对1的变构作用模式的药理学验证,表明这是多巴胺功效的NAM,并确定了这种变构的结构决定因素。我们发现关键的结构部分对于功能亲和力和负的协同作用很重要,而硫代嘧啶在5和6位的功能化导致类似物具有不同的协同作用谱。连续的化合物迭代产生了在功能亲和力方面表现出10倍改善的类似物,以及与多巴胺亲和力和功效增强的负协同性。此外,我们的研究揭示了一个片段样的核心,该核心保持了较低的μM亲和力和强大的负协同作用,并显着提高了配体效率。

two neutral ligands (L3, L4) and of their H2L3(ClO4)2∙2H2O, H2L4(ClO4)2∙2H2O, H2L3(PF6)2, and H2L3(PF6)2∙2H2O anioncomplexes were determined by single crystal X-ray diffraction. The formation of anion–π interactions is the leitmotiv of these complexes, both in solution and in the solidstate, although hydrogen bonding and/or formation of salt-bridges can contribute to their stability.
