Understanding drug-protein interactions and downstream effects of these interactions
underpins much of clinical pharmacology. By studying the protein targets of a small
molecule we can learn about the action of this compound in the body, and this
information can lead to greater understanding of mechanisms and clinical effects.
We probed the polypeptide interactions of five small molecules using a human
vascular phage display library, with the intention to elucidate previously unknown
protein targets for the small molecule in human vasculature. A method for studying
the chemical nature of this interaction was also developed.
The photochemical immobilisation system used - Magic Tag® - was developed as a
means of immobilising small molecules without concealing any facet of the
molecule from the interaction study. Five different photochemistries are displayed in
a multi-well format, to maximise diversity in the display of the small molecule. A
human vascular tissue T7Select® bacteriophage display library was prepared from
internal mammary artery tissues donated from patients undergoing coronary artery
bypass surgery. Biopanning of the immobilised small molecule against this library
allowed hypothesis generating analysis of small molecule-polypeptide interactions.
Because of the non-selective nature of the photochemical immobilisation of the
small molecule, several regioisomers might be expected to form on the Magic Tag®
surface. To be able to connect a protein interaction with a specific face of the small
molecule, analysis of this regio-non-specific interaction must be undertaken. For this
purpose a cleavable resin analogue of the Magic Tag® surface was prepared.
