JMU Würzburg Project Title: Generation and Screening of Chemically Diverse Cyclic Peptide Libraries Objectives: 1. Establish and evaluate cyclic peptide libraries in microarray format. 2. Screen and optimize cyclic β-catenin binders. 3. Produce prioritized cyclic peptide leads in preparative amounts for downstream studies.

Project Overview: A key challenge in peptide drug discovery is combining high affinity and specificity with compact size, stability, and cellular activity. Cyclization can improve these properties, but optimization requires efficient screening of chemically diverse peptide libraries. This project will develop and apply microarray-based cyclic peptide libraries to discover and optimize β-catenin binders. Sequence and cyclization-linker libraries will be combined directly during array production, enabling parallel evaluation of different cyclization chemistries. Additionally enzymatic cyclization approaches developed by EnzyTag will be applied on synthetic libraries. Using automated parallel synthesis and combinatorial array printing the number of cyclic peptide variants will be further increased and screened within a single campaign. Promising binders will be prioritized based on affinity, specificity, and cyclization-dependent improvements and synthesized in preparative amounts for downstream biophysical and cellular characterization. Contribution to the overall research program: Provides cyclic β-catenin binders with improved affinity, stability, and pharmacological properties and guides the selection of optimized leads for cellular studies. Skills and research profile: Experience with peptide or organic synthesis and peptide modification; protein handling in biochemical assays. Experience with macrocyclization, peptide libraries, or biophysical interaction analysis advantageous. Salary: The position is funded by the Horizon Europe MSCA-DN project FlexCAT (Grant Agreement No. 101311592) for three years. The selected candidate will be offered a competitive salary comprising a Living Allowance (adjusted by the country correction coefficient), a Mobility Allowance, and, if applicable, a Family Allowance. All allowances are subject to applicable social security contributions and taxation. Planned secondment: 1. Host: EnzyTag; Supervisor: Dr. Anna Koijen; Length: 3 months. Purpose: Training in advanced peptide macrocyclization strategies and transfer of these approaches into high-throughput screening formats.
