Zhang, Zhongsheng published the artcileStructure-guided discovery of selective methionyl-tRNA synthetase inhibitors with potent activity against Trypanosoma brucei, COA of Formula: C7H8BClO2, the publication is RSC Medicinal Chemistry (2020), 11(8), 885-895, database is CAplus and MEDLINE.
Based on crystal structures of Trypanosoma brucei methionyl-tRNA synthetase (TbMetRS) bound to inhibitors, we designed, synthesized, and evaluated two series of novel TbMetRS inhibitors targeting this parasite enzyme. One series has a 1,3-dihydro-imidazol-2-one containing linker, the other has a rigid fused aromatic ring in the linker. For both series of compounds, potent inhibition of parasite growth was achieved with EC50 < 10 nM and most compounds exhibited low general toxicity to mammalian cells with CC50s > 20 000 nM. Selectivity over human mitochondrial methionyl tRNA synthetase was also evaluated, using a cell-based mitochondrial protein synthesis assay, and selectivity in a range of 20-200-fold was achieved. The inhibitors exhibited poor permeability across the blood brain barrier, necessitating future efforts to optimize the compounds for use in late stage human African trypanosomiasis.
