Structure-Activity Relationship Studies of Retro-1 Analogues against Shiga Toxin
High-throughput screening has shown that Retro-1 inhibits ricin and Shiga toxins by diminishing their intracellular trafficking via the retrograde route, from early endosomes to the Golgi apparatus. To improve the activity of Retro-1, a structure-activity relationship (SAR) study was undertaken and yielded an analogue with a roughly 70-fold better half-maximal effective concentration (EC50) against Shiga toxin cytotoxicity measured in a cell protein synthesis assay.
Thermolysis and radiofluorination of diaryliodonium salts derived from anilines
Aniline-derived diaryliodonium salts were synthesized and functionalized in good to excellent yields by judicious utilization of electron-withdrawing protecting groups. This simple approach opens another route to radiolabeling amino arenes in relatively complex molecules, such as flutemetamol.
