Chemical tools for (a) detection and (b) modification of interactions in live cells
The main aim is to develop low-molecular weight chemical tools to image, study and control biological systems through mapping and subsequently modifying interactions between biochemical targets in live cells (figure). In particular:
- Fluorescent and bioluminescent molecular probes for sensing pairs of analytes to associate biochemical changes inside cells with the development of disease (e.g. lung and prostate cancer).
- Non-genetic methods for in situ tagging of endogenous proteins to visualise endogenous proteins and study their interactions in live cells.
- Multiplexing assays (based on small molecules) for high-throughput screening to improve the identification of most promising small molecule drug candidates and deciphering their mechanism of action (also within the ERIC EU-Openscreen consortium and POL-Openscreen initiative)
These tasks encompass, among others:
- Organic synthesis of probes (low molecular weight fluorophores and bioluminophores)
- Comprehensive spectroscopic analysis (in cuvettes and on microplates)
- Assay development and microscopic imaging of live cells through confocal microscopy (including e.g. FRET and FLIM)
- Flavin-based fluorescent probes and singlet-oxygen generators (prof. Marek Sikorski at the Faculty of Chemistry, Adam Mickiewicz University in Poznan)
Ongoing research projects:
1. Masked bioluminogenic substrates for a selective imaging of the biochemical parameters of cancer.
NCN – SONATA 13
2. MultiGATE: dual-analyte responsive fluorescent probes for a real-time multi-parametric sensing in cellular models.
FNP - HOMING 4
