FunctionPublication Abstract from PubMedFluorination is a well-known strategy for improving the bioavailability of drug molecules. However, its impact on efficacy is not easily predicted. On the basis of inhibitor-bound protein crystal structures, we found a beneficial fluorination spot for inhibitors targeting methionyl-tRNA synthetase of Trypanosoma brucei. In particular, incorporating 5-fluoroimidazo[4,5-b]pyridine into inhibitors leads to central nervous system bioavailability and maintained or even improved efficacy. 5-Fluoroimidazo[4,5-b]pyridine Is a Privileged Fragment That Conveys Bioavailability to Potent Trypanosomal Methionyl-tRNA Synthetase Inhibitors.,Zhang Z, Koh CY, Ranade RM, Shibata S, Gillespie JR, Hulverson MA, Huang W, Nguyen J, Pendem N, Gelb MH, Verlinde CL, Hol WG, Buckner FS, Fan E ACS Infect Dis. 2016 Jun 10;2(6):399-404. doi: 10.1021/acsinfecdis.6b00036.
