摘要:

目前, DNA编码分子库技术(DNA-encoded library, DEL)已经成为新药研发中不可或缺的重要技术平台. 过去30年DEL技术不断发展成熟, DEL兼容化学反应也发展迅速, 极大地改善了DEL的化学多样性, 并推动了其在药物发现中的应用. 通常, DEL的筛选主要是基于亲和力的固相筛选, 将纯化后的靶点蛋白固载在基质上, 然后通过物理洗脱的方式将结合分子与背景分子分离开来. 近年来, 一系列在液相中进行DEL筛选的新方法被研发出来, 使得适用于DEL筛选的靶点范围被进一步扩大, 揭示了DEL作为有效工具探索基础生物学的潜力. 本文综合评述了DEL技术的液相筛选方法及应用, 并对DEL技术应用于复杂生物靶点以及功能性筛选进行了展望.

Abstract:

DNA-encoded library(DEL) has become a nearly indispensable technology platform for the development of new drugs in the pharmaceutical industry. The DEL technology has become matured over the past three decades and the rapid development of DEL-compatible chemistries has tremendously improved the chemical diversity of DELs and promoted its application in drug discovery. DEL technology has been widely adopted by pharmaceutical companies, and numerous clinical candidates have been identified from DEL selection. Usually, the selection of DEL is mainly affinity-based selection on solid-phase. The purified target protein is immobilized on the matrix, and then the binders are separated from non-binders by physical washes. In recent years, a series of in-solution selection methods for DEL have been developed, which has further expanded the target scope suitable for DEL and revealing the potential of DEL as an effective tool to explore fundamental biology. This review mainly introduces the selection methods of DEL in-solution phase and their applications, and finally gives a brief outlook on the application of DEL technology to complex biological targets and functional selection.

Key words: DNA-encoded library, Drug discovery, Drug selection, In-solution selection
