Development and Evaluation of an Immunological Approach for the Identification of Novel Acetyl Coenzyme-A Carboxylase Inhibitors: Assay Optimization and Pilot Screen Results
Bibliographic record
Abstract
Cyclohexanediones, aryloxyphenoxypropionates, indolizidinediones, and triazinediones are four known structural classes of herbicides that inhibit acetyl coenzyme-A carboxylase (ACCase; EC 6.4.1.2). An immunological study to determine the potential of ACCase inhibitor-specific monoclonal antibodies as screening tools to identify novel lead chemistry was undertaken. Using two cyclohexanedione-specific monoclonal antibodies (mAb A and mAb B; Webb, S. R.; Hall, J. C. J. Agric. Food Chem. 2000, 48, 1210-1218) and three different cyclohexanedione hapten coating conjugates, competitive indirect enzyme-linked immunosorbent assays (ciELISA) were developed. Cross-reactivity of the monoclonal antibodies with four structural classes of ACCase inhibitors revealed that the ciELISA using mAb A and a modified cyclohexanedione hapten coating conjugate detected analogues from all four known classes of ACCase inhibitors. A pilot screen using this ciELISA format identified two novel ACCase inhibitors, demonstrating the potential for antibodies as rapid and cost-effective screening tools for identifying novel lead chemistry in pesticide discovery programs.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
