New phosphonylation route of a series of 2-AlkylBenzimidazole derivatives: Synthesis, characterization, biological evaluation, ADMET prediction, molecular docking and DFT studies
Bibliographic record
Abstract
A series of new benzimidazole phosphonate derivatives was obtained via nucleophilic addition of triethyl phosphite to the imine of the imidazole subgroup under solvent-free conditions. Structures of the formed products were confirmed using spectroscopic data (ATR-FTIR, 1H-NMR, 13C-NMR, and MS). The antimicrobial profiles of the synthesized compounds were examined, and promising activities against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans were revealed, showing significant inhibition zone diameters ranging from 13 to 17 mm. Alongside these experimental findings, in silico investigations were conducted using ADMET characteristics, which showed a positive pharmacokinetic profile and provided valuable information on potential interactions with target molecules. Besides, docking studies against tested microorganisms revealed further insights on the compounds’ binding interactions with the active sites. Finally, DFT analysis was performed to shed light on the synthesis of novel molecules.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
