(i) Study shows the generation of a high-quality stereo- and regiodefined DNA-encoded chemical library - (ii) Identified ligands against tumor-associated antigens can serve as vehicles for pharmacodelivery applications
SIENA, ITALY / ACCESSWIRE / April 12, 2021 / Philogen S.p.A., a listed clinical-stage biotechnology company focused on the development of innovative medicines based on tumor-targeting antibodies and small molecule ligands, is pleased to announce a publication describing the construction of a DNA-encoded chemical library (DEL) that was successfully screened against multiple protein targets, yielding potent and selective small molecule binders against disease-relevant antigens. The paper entitled 'Stereo- and regiodefined DNA-encoded chemical libraries enable efficient ligand discovery for conditional CAR-T-cell activation and tumour targeting' was published in the prestigious, peer-reviewed journal Nature Chemistry and the underlying work was a result of the successful collaboration between scientists at Philochem AG, the Swiss subsidiary of Philogen, and ETH Zurich.
By constructing a high-quality stereo- and regiodefined DNA-encoded chemical library, ligands against tumor markers could be identified and validated using various orthogonal analytical methodologies.
This work underlines the potential of the DEL technology for ligand discovery with a special emphasis on the discovery of binding molecules that could potentially serve as vehicles for pharmacodelivery applications or as inhibitors of biologically relevant targets.
Dario Neri, Chief Executive Officer of Philogen commented: 'The DEL technology is getting closer and closer to the performance of another class of encoded libraries (i.e., antibody phage display technology), which has been practiced by the Philogen group for many years. Small molecule ligands isolated from DEL libraries exhibit antibody-like performance, they work in ELISA methodologies, and they can recognize their target with potency in the nanomolar concentration range.'
