rapid structure evaluation prior to off-bead resynthesis. Subsequently, a series of 19 compounds were prepared and tested using a competitive fluorescence polarization assay, which led to the discovery of peptide ligands with low micromolar binding affinity towards the DD. The methodology represents a rapid approach for identification of a novel structure scaffold, where the screening and initial structure
在计算设计的基础上,已针对由小三肽和三唑封端的N末端组成的微粒编码的PEGA1900珠制备了聚焦的单珠单化合物文库。针对人FKBP12蛋白的双点突变版本(称为去稳定结构域(DD))筛选了该文库。受解码的文库命中率的启发,在新颖的珠上检测方法中筛选了非天然肽结构,这对于在离珠重新合成之前进行快速结构评估很有用。随后,制备了19种化合物,并使用竞争荧光偏振分析法进行了测试,这导致发现了对DD具有低微摩尔结合亲和力的肽配体。该方法代表了一种鉴定新型结构支架的快速方法,
