2,4‐Disubstituted Phenylhydrazonopyrazolone and Isoxazolone Derivatives as Antibacterial Agents: Synthesis, Preliminary Biological Evaluation and Docking Studies
Bibliographic record
Abstract
Abstract A series of new 2,4‐ disubstituted phenylhydrazonopyrazolone and isoxazolones have been synthesized and evaluated for antibacterial activity. These compounds incorporated the bioactive moieties 3‐methyl isoxazolone and 3‐methyl pyrazolone. Based on the preliminary results, evaluation of these new compounds as potential antimicrobial agents revelead that four of them which incorporate the isoxazolone moiety exhibited selective antimicrobial activity against Gram‐positive bacteria with MICs for S. aureus in the 50–100 μgmL −1 range. Additionally, docking studies were performed in order to explore the possible binding poses in the MurB protein of S. aureus and the results were correlated to the antimicrobial results reported herein.

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.
