Spatially addressable combinatorial libraries were synthesized by solution phase chemistry and screened for binding to human serum albumin. Members of arylidene diamide libraries were among the best hits found, having submicromolar binding affinities. The results were analyzed by the frequency with which particular substituents appeared among the most potent compounds. After immobilization of the ligands either through the oxazolone or the amine substituent, characterization by surface plasmon resonance showed that ibuprofen affected the binding kinetics, but phenylbutazone did not. It is therefore likely that these compounds bind to Site 2 in sub domain IIIA of human serum albumin (HSA).
通过溶液相化学合成了空间可寻址的组合库,并对其与人体血清白蛋白的结合能力进行了筛选。在发现的优秀结合分子中,有一类是芳亚基二酰胺类化合物,它们具有亚微摩尔级别的结合亲和力。通过对这些最强效化合物中特定取代基出现的频率进行分析,得出了结果。通过醛酮或胺取代基将配体固定化后,利用表面等离子体共振技术进行表征,结果显示布洛芬影响了结合动力学,而保泰松则没有。因此,这些化合物很可能结合在人血清白蛋白(HSA)亚域IIIA的第2位点上。
