用可扩增的DNA标签编码化合物有助于发现蛋白质的小分子配体。为了研究立体化学和区域化学对配体发现的影响,我们以2-叠氮-3-碘苯丙酸为基础,合成了一个包含670,752个衍生物的dna编码文库。该文库针对多种蛋白质进行筛选,得到了特定的配体。获得的一组具有药物相关性的蛋白质靶点的选择指纹清楚地显示了邻位、间位或副区域异构体的优先富集,这在没有DNA的情况下通过亲和测量得到了实验验证。发现的配体包括新的选择性酶抑制剂和肿瘤相关抗原的结合物,使条件嵌合抗原受体T (CAR-T)细胞活化和肿瘤靶向。
The encoding of chemical compounds with amplifiable DNA tags facilitates the discovery of small molecule ligands for proteins. In order to investigate the impact of stereo- and regio-chemistry on ligand discovery, we synthesized a DNA-encoded library of 670,752 derivatives based on 2-azido-3-iodophenylpropionic acids. The library was selected against multiple proteins and yielded specific ligands. The selection fingerprints obtained for a set of protein targets of pharmaceutical relevance clearly showed the preferential enrichment of ortho-, meta- or para-regioisomers, which was experimentally verified by affinity measurements in the absence of DNA. The discovered ligands included novel selective enzyme inhibitors and binders to tumor-associated antigens, enabling conditional chimeric antigen receptor T (CAR-T) cell activation and tumor targeting.
