Contribution & Novelties
The seminar provides an in-depth look at the development of D-peptide therapeutics, a relatively novel approach in drug discovery. The speaker details the use of mirror-image phage display to overcome the lack of natural D-peptide binders, and the subsequent structure-based optimization to achieve picomolar affinity. The clinical candidate CPT31 shows exceptional breadth and potency against HIV isolates, outperforming broadly neutralizing antibodies. The talk also highlights the potential of mirror-image biology for creating synthetic proteins and machines, contributing to the field of synthetic biology.
