Abstract
Bruceantin (1), a classical quassinoid with the highest reported antimalarial activity among the quassinoids examined thus far, was selected as a natural product lead for the design of a series of A/B-ring analogs. A viable strategy for the synthesis of the series was developed. The functionalized A-ring and the C-15 ester moiety in bruceantin are incorporated in all designed compounds. The preliminary bioassay results will be discussed in detail. Keywords: bruceantin, partial analogs, bioassay, structure activity relationships, antileukemic and antimalarial activities

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
