Abstract: Antimicrobial resistance (AMR) poses a significant threat to human health around the world. Though bacterial pathogens can develop resistance through a variety of mechanisms, one of the most prevalent is the production of antibiotic-modifying enzymes like FosB, a Mn2+-dependent L-cysteine or bacillithiol (BSH) transferase that inactivates the antibiotic fosfomycin. FosB enzymes are found in pathogens such as Staphylococcus aureus, one of the leading pathogens in deaths associated with AMR. fosB gene knockout experiments establish FosB as an attractive drug target, showing that the min. inhibitory concentration (MIC) of fosfomycin is greatly reduced upon removal of the enzyme. Herein, we have identified eight potential inhibitors of the FosB enzyme from S. aureus by applying high-throughput in silico screening of the ZINC15 database with structural similarity to phosphonoformate, a known FosB inhibitor. In addition, we have obtained crystal structures of FosB complexes to each compound Furthermore, we have kinetically characterized the compounds with respect to inhibition of FosB. Finally, we have performed synergy assays to determine if any of the new compounds lower the MIC of fosfomycin in S. aureus. Our results will inform future studies on inhibitor design for the FosB enzymes.

YieldReaction ConditionsOperation in experiment
With acetic anhydride; at 100℃; for 3.0h;Product distribution / selectivity; Under a nitrogen atmosphere, to 3-cyclopropyl-l-(2-fluoro- 4-iodo-phenyl)-6-methylamino-1H-pyrimidine-2,4-dione 52 (34.4 g) and 2-methyl-malonic acid 54 (15.2 g) was added acetic anhydride (34.4 ml), and the mixture was stirred with heating at 100C for 3 hrs. After allowing to cool to 50C, acetone (68.8 ml) was added dropwise, and the mixture was stirred as it was for 30 min. Water (172 ml) was further added dropwise, and the mixture was stirred for 1 hr. After allowing to cool to room temperature with stirring, the precipitated crystals were collected by filtration and dried to give crude crystals (37.7 g, LC purity 91%) of 3- cyclopropyl-1-(2-fluoro-4-iodo-phenyl)-5-hydroxy-6,8-dimethyl- lH,8H-pyrido[2,3-d]pyrimidine-2,4,7-trione 55. Isopropanol (92.0 ml) was added to the obtained crude crystals (30.7 g), and the mixture was stirred at room temperature for 4 hrs. The crystals were collected by filtration and dried to give 3-cyclopropyl-l-(2-fluoro-4-iodo-phenyl)-5-hydroxy-6,8-dimethyl-1H,8H-pyrido[2,3- d]pyrimidine-2,4,7-trione 55 (25.9 g, yield from 76,58%) as pale-yellow crystals.

21% With acetic anhydride; at 100℃; for 2.0h;Product distribution / selectivity; To a 2: 1 mixture (34.6 g) of 3-cyclopropyl-l-(2-fluoro-4- iodophenyl)-6-methylamino-lH-pyrimidine-2,4-dione 52 and 1- cyclopropyl-3-(2-fluoro-4-iodo-phenyl)6-methylamino-1H- pyrimidine-2,4, -dione 53 obtained in Step 4, and 2-methylmalonic acid 54 (10.2 g) was added acetic anhydride (173 ml), and the mixture was stirred at 100C for 2 hrs. After allowing to cool to room temperature, the reaction mixture was concentrated under reduced pressure. Acetone (104 ml) was added to the residue, and the mixture was stirred with heating under reflux for 30 min. After allowing to cool to room temperature, the precipitated crystals were collected by filtration and dried to give 3- cyclopropyl-1-(2-fluoro-4-iodophenyl)-5-hydroxy-6,8-dimethyl- lH,8H-pyrido[2,3-d]pyrimidine-2,4,7-trione 55 (15.1 g, yield from 48,21%) as colorless crystals.
