Within this call EU-OPENSCREEN-DRIVE offers transnational access to state-of-the-art chemical synthesis facilities for the production of conjugated probe molecules to support affinity-based studies:
Probe synthesis: Department of Molecular Probes and Prodrugs at IBCH PAS aims at the development of small molecule chemical tools to investigate biological models. In particular, we have an extensive experience in the development of fluorescent and bioluminescent probes to sense biochemical analytes in vitro and in live cells and more complex cellular models. In addition, through a thorough expertise in organic synthesis we develop advanced tools for labelling (reactive probes) and controlling (prodrugs) proteins.
Within this project, IBCH PAS offers support for the synthesis of 2-3 probes for studying target engagement and/or fluorescent labelling, on the basis of one validated bioactive compound with identified activity and benign point of attachment of a potential linker on its scaffold. Probes will be composed of variable length linkers connecting a ligand (derived by the user) with a specific tag (e.g. click chemistry handle for resin-based purification or fluorophore for imaging). Synthesis will be performed in a convergent manner with several linker-tag adducts being synthesized in parallel and then attached through a stable moiety to the identified hit scaffold.
Proteomics: Centre for High Throughput Screening Studies offers access to advanced infrastructure for assay development, miniaturisation and screening of large libraries of small molecules using various modes of detection (fluorescence, luminescence, imaging and variants thereof) as well as expertise in image analysis. In connection with biological mass spectrometry facility we have an experience and are also able to provide advanced follow-up studies in proteomics and metabolomics.
Within this project, IBCH PAS provides access to the infrastructure and expertise in target identification through proteomic analysis. Both targeted and non-targeted proteomic workflows are available involving purification and mass spectrometry analysis. Available equipment includes but is not limited to MALDI/TOF/TOF, nanoLC-ESI-qOrbitrap with Advison NanoMate add-on TripleQuad LC-ESI-MS.
The department of Chemical Biology at HZI aims at discovering new antibacterial and antiviral drugs, characterizing their functionality and optimizing their properties. HZI focuses on infection research and small molecules that can function as antimicrobial or antiviral agents, interfere with pathogenicity factors or stimulate the immune system.
Within this call, HZI offers expertise in the area of drug conjugates to synthesize functionalized chemical probes. HZI has ample experience in the synthesis of bacteria-targeted conjugates that combine a targeting and an effector moiety (an antibiotic, a fluorophore, etc) through various cleavable and non-cleavable linkers. HZI will support preparation of probes for affinity-based target identification using chemoproteomics.
Within this call, Medicinal Chemistry group at FMP offers chemical probe optimization (activity, selectivity, linker attachment exploration) and follow-up modification towards labeled chemical probes for target deconvolution, fluorescent labeling, and crosslinking.
