Abstract
Bisphosphonate drugs are well known to inhibit osteoclastic activity and have been proposed for the management of bone diseases, including periodontitis which is associated with alveolar bone destruction. In this study, we evaluated the effects of four arylsulfonamide bisphosphonates on growth of the periodontopathogenic bacterium Porphyromonas gingivalis as well as their capacity to reduce cytokine secretion by lipopolysaccharide (LPS)-stimulated oral epithelial cells. The growth of P. gingivalis was inhibited by (4'-Chloro-biphenyl-4-sulfonylamino)methyl-1,1- bisphosphonic acid while the three other arylsulfonamide bisphosphonates ((4-Methoxy-phenylsulfonylamino)methyl-1,1- bisphosphonic acid, (4-Nitro-phenylsulfonylamino)methyl-1,1-bisphosphonic acid, and (Biphenyl-4-sulfonylamino) methyl-1,1-bisphosphonic acid) had no effect. Growth inhibition was more pronounced under an iron-restricted condition. All four arylsulfonamide bisphosphonates decreased the production of the pro-inflammatory cytokines IL-6 and IL-8 by Aggregatibacter actinomycetemcomitans LPS-stimulated oral epithelial cells. In conclusion, we uncovered additional properties of bisphosphonates that may be beneficial for the treatment of periodontal diseases. In particular, (4'-Chlorobiphenyl- 4-sulfonylamino)methyl-1,1-bisphosphonic acid combines the already disclosed antiresoptive activity with antiinflammatory and antibacterial properties.

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
