of pyrones and pyrimidones was synthesized, and their potential to act as photoaffinity probes for nondirected affinity-based protein profiling in several crude cell lysates was evaluated. Further “proof-of-principle” experiments demonstrate that a pyrimidone tag on an appropriate scaffold is equally capable of proteome labeling as a benzophenone.
α-吡喃酮和嘧啶酮是天然产物和生物活性化合物中常见的结构基序。它们还显示出产生高能中间体的光化学,该中间体可能具有蛋白质反应性。合成了吡喃酮和嘧啶酮的文库,并评估了它们在几种粗细胞裂解物中用作基于非定向亲和力的蛋白质谱分析的光亲和探针的潜力。进一步的“原理证明”实验表明,适当支架上的嘧啶酮标签具有与二苯甲酮同样的蛋白质组标记能力。
