Abstract:
Photoreactive groups have been used in photoaffinity labelling of chemical macromolecules via the generation of highly reactive species upon short wave light irradiation. One of the most efficient photoreactive functional groups is trifluoromethyl aryldiazirine (TFMAD). This compound was synthesised as part of the work discussed in this thesis, making use of microwave irradiation to shorten reaction times (Chapter I). An investigation of properties allowed the development of three different applications for conjugation to biomolecules. The first application consisted of the development of an approach for generation of small-molecule microarrays, where a 2,000 compound library was immobilised onto the glass surface through carbene insertion. The microarray was then used to screen for potential binders to beta-transducin repeat containing protein (b-TrCP1) allowing the reduction of possible candidates to less than 25 compounds (Chapter II). The second application was the synthesis of two probes to allow the selective delivery of active compounds inside specific organelles or cells. The diazirine moiety was used as a rapid way to covalently capture a number of cargos. The approach allowed a peptoid and an anticancer drug to be conjugated to the two probes and their cell penetrability properties and therapeutic effect were studied, respectively (Chapter III). Finally, the insertion properties of TFMAD were used to develop approaches to attach DNA onto microspheres and the efficiency of this delivery system was evaluated (Chapter IV).
