    DNA-Encoded Library Technology (DELT)

    DNA-Encoded Library Technology (DELT) is a fast-growing, cutting-edge discovery technology used to identify small molecule hits or leads against a variety of drug targets. The main principle of DELT is to encode each compound in the library with a unique DNA barcode. Thereby library of billion compounds can be screened as a mix in a single test tube and the active compounds are identified by amplification and sequencing of the DNA barcodes. Our DELT platform is built upon our thousands of novel building blocks and many year accumulated chemistry expertise with differentiation in diversity and quality of the libraries.

    Strategies of DELT Library Design

    Diverse Library based on the combination of PB’s building blocks and known and/or newly developed DNA-compatible reactions.

    Target Focused Library based on novel building blocks and unique structural features specifically for interested targets such as kinases, bromodomains, and targets suitable for covalent inhibitor development etc.
