Fragment screening of a thermostabilized mGlu5 receptor using a high-concentration radioligand binding assay enabled the identification of moderate affinity, high ligand efficiency (LE) pyrimidine hit 5. Subsequent optimization using structure-based drug discovery methods led to the selection of 25, HTL14242, as an advanced lead compound for further development. Structures of the stabilized mGlu5 receptor
使用高浓度放射性配体结合测定的热稳定的mGlu 5受体的片段筛选能够鉴定中等亲和力,高配体效率(LE)嘧啶命中5。随后使用基于结构的药物发现方法进行的优化导致选择25 HTL14242作为进一步开发的高级先导化合物。分别在2.6和3.1Å的分辨率下确定了稳定化的mGlu 5受体的结构,该受体与25和该系列的另一个分子14形成复合。
