- 요약DNA-encoded chemical libraries (DELs) are powerful tools to rapidly survey chemical space for biological activity in a cost- and time-efficient manner by harnessing combinatorial chemistry and next-generation DNA sequencing to enable rapid drug discovery. However, as opposed to traditional high throughput screening, current DNA-encoded library selection methods primarily focus on binding-based assays against defined targets in vitro and cannot access the biological relevance and novelty of insight that phenotypic cell-based assays can yield. Combining the power of combinatorial chemistry through the application of DNA-encoded chemical libraries with the depth of complex insight furnished by phenotypic assays would greatly reduce the cost of academic and industrial hit discovery, as well as speed up design-make-test cycles to accelerate the medicinal chemistry lead optimization process.In this thesis I establish a methodology to transfect DNA-encoded small molecules into mammalian cells, and probe cellular function of these DNA-encoded small molecules by assaying for compound-induced gene expression, which identification of active small molecules by sequence analysis of their cognate DNA barcodes.I describe the concept and development of tools and methods and present a covalent labeling and immunoprecipitation strategy to enrich DNA barcodes encoding active compounds from cell-based transfection experiments. Compound-induced gene expression is linked to covalent labeling of DNA barcodes present in an activated cell. This DNA labeling functions as a type of activity recording that can summate both transient and sustained cellular signaling outputs and provides a compound-activity-dependent purification tag that allows recovery and sequencing of DNA barcodes. I also identify an additional tool compound that can be included in a future model DEL and report the establishment of a DNA sequencing protocol spanning library preparation and bioinformatic analysis. I discuss next experimental steps, important limitations of the current approach, and future directions of this methodology, as well as discusses potential application of this work towards the related fields of synthetic biology and biocomputing.
