NMR作为一种化合物结构检测方法,在FBDD筛选中可以用于检测片段与生物大分子的结合情况,通常氢谱NMR使用较多。检测含氟片段与靶点蛋白是否存在结合作用时,可以使用氟谱检测(19F-NMR)。不过并非所有含氟片段均适合氟谱检测,需要构建合适的含氟片段库。
陶术生物提供的BIONET含氟片段库经过精心设计,是FBDD筛选的有力工具。整个库经过了几道工序精心挑选:1. 挑选重原子数量小于21个的含氟片段;2. 类药性过滤,使用Lilly MedChem Rules和FAF-Drugs规则过滤,确保片段分子具有较好的类药性;3. PAINS过滤,剔除掉容易发生非特异性结合反应的化合物结构;4. 剔除可能发生聚合反应的化合物,通过spin-spin relaxation Carr-Purcell-Meiboom-Gill NMR实验剔除可能自组装聚合的化合物,减少脱靶、假阴性等问题;5. 质量检测,使用19F NMR和1H NMR进行结构检测,经过重复检测,剔除NMR谱图不一致的结构;6. 溶解度测试,在PBS中可达到100μM,在DMSO中可达到200mM,满足实验溶解度需求。BIONET含氟片段库经过层层筛选,得到533种高品质的含氟片段分子,可用于各类FBDD的筛选方法中。
