Short personal activity proposal for the COST Action CA15135 (max 1000 characters)

One of the tasks in this COST action is to design novel or identify existing bioactive compounds, which could interact selectively with two or more macromolecular targets. As every target protein has its own catalytic or other biological activity, different activity evaluation tests are used to identify interacting compounds. Versatility of biophysical interaction methods could be employed both for primary screening and ligand affinity ranking. Our laboratory can propose fluorescence based thermal shift assay (also known as differential scanning fluorimetry), which enables quick selection of interacting small molecules according to changes in protein stability (melting temperature). It can be used to detect binding in very wide affinity range.

Presently we are working with target proteins: carbonic anhydrases (we have all 12 catalytically active proteins), Hsp90 (alpha and beta isoforms), and several others (HDAC8, sirtuin2, etc.).
