additional information | a series of 4,5-dioxo-1,4,5,6-tetrahydropyrimido[4,5-c]pyridazines are designed to improve binding affinity as dihydropteroate synthase inhibitors, overview. The N-methyl ring substitution is removed to improve binding within the pterin pocket, and the length of the side chain carboxylic acid is optimized to fully engage the diphosphate binding site. Evaluation by evaluated an enzyme activity assay, X-ray crystallography, isothermal calorimetry, and surface plasmon resonance to obtain a comprehensive understanding of the binding interactions from structural, kinetic, and thermodynamic perspectives | Bacillus anthracis |
