the range of modern drug discovery tools, such as receptor modeling and ligand docking. Although the receptor models described to date share a majority of common traits, they display discrete alternatives in amino-acid conformation, rendering ligand binding modes quite different. Such variations impede structure-based drug design in the H3R field. In the present study, we used a combination of medicinal
由于组胺H3受体(CN3)参与主要的CNS功能,因此它是深入的药物化学研究的主题,并得到一系列现代药物发现工具的支持,例如受体建模和配体对接。尽管迄今为止描述的受体模型具有大多数共同特征,但它们在氨基酸构象上显示出离散的替代方案,从而使配体结合模式完全不同。这种变化阻碍了H3R领域中基于结构的药物设计。在本研究中,我们结合了药物化学,受体指导和基于配体的方法来阐明拮抗剂的结合方式。这些方法朝着垂直于膜平面的配体方向汇聚,将跨膜螺旋5的Glu206与细胞外环的酸性氨基酸桥接。
