The fibrillary aggregation of the protein alpha synuclein (Asyn) is a hallmark of Parkinson's disease, and the identification of small molecule binding sites on fibrils is essential to the development of diagnostic imaging probes. A series of molecular modeling, photoaffinity labeling, mass spectrometry, and radioligand binding studies were conducted on Asyn fibrils. The results of these studies revealed
蛋白质α突触核蛋白(Asyn)的纤维状聚集是帕金森氏病的标志,并且原纤维上小分子结合位点的鉴定对于诊断成像探针的开发至关重要。对Asyn原纤维进行了一系列分子建模,光亲和标记,质谱和放射性配体结合研究。这些研究的结果表明,原纤维Asyn中存在三个不同的结合位点,它们能够以中等至高亲和力结合小分子。这些结合位点的氨基酸残基的知识对于设计能够对Asyn的原纤维种类成像的高亲和力探针非常重要。
