Science重磅丨DNA编码化合物库(DELs)即将被取代 . . . DNA 编码化合物库 ( DNA encoded libraries, DELs ) 是一种与特定 DNA 序列共价连接的小分子化合物库,通过对结合化合物的 DNA 序列进行扩增和测序,可以有效地识别该化合物,从而进行快速而大规模的高通量筛选。 这种 DNA 修饰的优势在于通量高、合成成本低,且编码能力强,对于一段碱基长度为 10 的 DNA,能编码 410 种小分子。 但为了保证 DNA 标签的完整性,能采用的修饰方式有限。 而这些 有限的修饰方式 以及 DNA 本身 都会影响小分子与蛋白的结合能力。 鉴于 编码化合物技术 在药物发现中的巨大潜力,当前急需一种信息载体更稳定、更多样化的互补平台来克服 DNA 编码的限制。
