In the quest to discover novel therapeutic agents and revolutionize drug development, scientists have continually sought innovative approaches to accelerate the identification of potential drug candidates. One ground-breaking solution that has emerged in recent years is the utilization of DNA-encoded libraries (DELs). DELs stand as a versatile and potent technology foundation for uncovering small molecule binders for biologically and pharmaceutically significant protein targets.
DELs encompass groups of compounds, each linked to unique DNA markers that function as amplifiable identification codes. With the progress made in DNA-compatible chemical reactions, selection techniques, next-generation sequencing, and data interpretation, DEL technology enables the creation and examination of libraries with unparalleled dimensions.

Traditional methods of drug discovery are often time-consuming, costly, and inefficient. They rely on screening vast collections of chemical compounds to identify molecules with the desired therapeutic properties. This approach not only demands enormous resources but also limits the scope of the search to a finite chemical space. Additionally, the identification and optimization of lead compounds frequently involve extensive hit-to-lead optimization, further elongating the drug development timeline. Another challenge is the high cost of synthesizing and screening chemical compounds with many promising molecules often being overlooked due to budget constraints.
DNA encoded libraries offer a paradigm shift in drug discovery by leveraging the power of molecular biology and high-throughput screening. This technology consists of four key elements or features:

DELs provide access to an unparalleled diversity of chemical compounds, increasing the chances of discovering unique drug candidates. In addition, high-throughput screening with DNA tags significantly accelerates the drug discovery process, reducing development timelines, while enabling efficient resource utilization, therefore, making drug discovery more cost-effective. In conclusion, DEL technology opens doors to innovative target-based and phenotypic drug discovery approaches.
