The rapid growth of demands for drug discovery has necessitated the ongoing pursuit of new methods for specific ligands screening and identification. This work combined receptor-affinity chromatography (RAC) with high-throughput sequencing techniques to rapidly screen and identify the specific ligands. By this method, immobilized angiotensin II type I receptor(AT1R) and endothelin receptor A(ETAR)
对药物发现需求的快速增长使得对特定配体筛选和鉴定的新方法的不断追求成为必要。这项工作将受体亲和层析 (RAC) 与高通量测序技术相结合,以快速筛选和鉴定特定的配体。通过该方法,利用基于RAC的固定化血管紧张素II I型受体(AT 1 R)和内皮素受体A(ET A R)从DNA编码文库中筛选铅。AT 1 R(配体A 1 , A 2)和ET A R(配体B 1 , B 2)的特异性配体) 是通过高通量测序技术解码后合成的。配体A 1、A 2对AT 1 R 和B 1、B 2对ET A R的解离速率常数( k d )分别为9.65×10 -4、31.1×10 -4和0.66、1.22 s -1峰分析测定。四种配体与受体的结合常数(K A)分别为5.4×10 6、3.3×10 6和1.6×10 6、2.2×10 5通过注射量依赖的方法。四种特异性配体的动力学和热力学参数与阳性药物相似。这表明他们有希望成为候选药物。通过
