Abstract
Due to overuse and/or misuse of antibiotics, antimicrobial resistance (AMR) has emerged to be a big threat to human and animal health. Developing new antimicrobial agents is becoming more urgent than ever along with increased appearance of antimicrobial resistant bacteria. We initiated a novel approach to reduce AMR development by chemically linking synergistic antibiotics and phytochemicals. Our first conjugate, sulfamethoxazole-gallic acid (Hybrid 1), was only effective towards Streptococci and Enterococci. To improve antimicrobial activity and bacterial susceptibility, we designed and synthesized four new conjugates, sulfamethoxazole-eugenol, sulfamethoxazole-protocatechuic acid, sulfamethoxazole-vanillic acid and sulfamethoxazole-caffeic acid. Compared to Hybrid 1, these four conjugates exhibited stronger antimicrobial activities towards all six tested Gram-positive and one tested Gram-negative bacteria. This implicates that synthesis of antibiotic-phytochemical conjugates is a promising strategy in developing novel antimicrobial agents.

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
