Abstract
A scalable process for manufacturing of the anticoronavirus clinical candidate AB-343 has been developed. The lactam-containing subunit of the molecule was prepared using a novel synthetic route involving a nitro-Michael reaction and a rhodium-catalyzed nitro group hydrogenation followed by in situ translactamization sequence as a key transformation. The drug substance was assembled via sequential amide coupling and deprotection reactions, followed by a final dehydration of a primary amide to the corresponding nitrile using T3P. AB-343 drug substance was successfully manufactured on a multikilogram scale using this route, which was suitable for supporting IND-enabling studies and Phase I clinical development.

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
