Structure-Based Design and Synthesis of tRNA-Guanine Transglycosylase (TGT) Inhibitors

Shigellosis is a highly infectious inflammatory disease causing 160 million episodes and 1.1 million fatalities, annually. The tRNA modifying enzyme tRNA-Guanine Transglycosylase (TGT) was shown to be necessary for efficient and selective translation of the transcription factor virF, which plays a significant role in the invasive mechanism of Shigella. Therefore, TGT is a promising and highly interesting target for the development of new drugs against Shigellosis. The aim of this project is the de novo design and synthesis of potential inhibitors against TGT using MOLOC, a molecular modeling program developed by Hoffmann-La Roche in Basel.
