Abstract
A group of biodegradable alanine-derived gemini quaternary ammonium salts (bromides and chlorides) with various alkyl chains and spacer lengths was tested for anti-adhesive and anti-biofilm activity. The strongest antifungal activity was exhibited by bromides with 10 and 12 carbon atoms within hydrophobic chains (N,N'-bis(1-decyloxy-1-oxopronan-2-yl)-N,N,N',N'-tetramethylpropane-1,3-diammonium dibromide and N,N'-bis(1-dodecyloxy-1-oxopronan-2-yl)-N,N,N',N'-tetramethylethane-1,2-diammonium dibromide). It was also demonstrated that these gemini surfactants enhanced the sensitivity of Candida albicans to azoles (itraconazole and fluconazole) and polyenes (amphotericin B and nystatine). Gemini quaternary ammonium salts effectively inhibited fungal cell adhesion to polystyrene and silicone surface. These compounds reduced C. albicans filamentation and eradicated C. albicans and Rhodotorula mucilaginosa biofilms, as it was shown in crystal violet and fluorescent staining. None of the tested compounds were cytotoxic against yeast mitochondrial metabolism.

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
