Abstract
α-Phosphomannomutase/phosphoglucomutase (αPMM/PGM) from P. aeruginosa is involved in bacterial cell wall assembly and is implicated in P. aeruginosa virulence, yet few studies have addressed αPMM/PGM inhibition from this important Gram-negative bacterial human pathogen. Four structurally different α-d-glucopyranose 1-phosphate (αG1P) derivatives including 1-C-fluoromethylated analogues (1–3), 1,2-cyclic phosph(on)ate analogues (4–6), isosteric methylene phosphono analogues (7 and 8), and 6-fluoro-αG1P (9), were synthesized and assessed as potential time-dependent or reversible αPMM/PGM inhibitors. The resulting kinetic data were consistent with the crystallographic structures of the highly homologous Xanthomonas citri αPGM with inhibitors 3 and 7–9 binding to the enzyme active site (1.65–1.9 Å). These structural and kinetic insights will enhance the design of future αPMM/PGM inhibitors.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
