Mechanistic studies in Acinetobacter baumannii demonstrated that this compound downregulated the PmrAB two-component system and abolished a lipid A modification that is required for colistin resistance. We now report the synthesis and evaluation of two separate libraries of substituted 2-aminoimidazole analogues based on this parent compound. From these libraries, a new small molecule was identified that lowers the minimum inhibitory concentration of colistin by up to 32-fold greater than the parent compound while also displaying less inherent bacterial effect, thereby minimizing the likelihood of resistance evolution.}, number={25}, journal={TETRAHEDRON}, author={Brackett, Christopher M. and Furlani, Robert E. and Anderson, Ryan G. and Krishnamurthy, Aparna and Melander, Roberta J. and Moskowitz, Samuel M. and Ernst, Robert K. and Melander, Christian}, year={2016}, month={Jun}, pages={3549–3553} } @article{richardson_furlani_podell_ackart_haugen_melander_melander_basaraba_2015, title={Inhibition and breaking of advanced glycation end-products (AGEs) with bis-2-aminoimidazole derivatives}, volume={56}, ISSN={["0040-4039"]}, DOI={10.1016/j.tetlet.2015.01.122}, abstractNote={Advanced glycation end-products (AGEs), unregulated modifications to host macromolecules that occur as a result of metabolic dysregulation, play a role in many diabetes related complications, inflammation and aging, and may lead to increased cardiovascular risk.
