Inhibition of protein synthesis by aminoglycoside???arginine conjugates
Bibliographic record
Abstract
Inhibition of translation by small molecule ligands has proven to be a useful tool for understanding this complex cellular mechanism, as well as providing drugs of significant medical importance. Many small molecule ligands inhibit translation by binding to RNA or RNA/protein components of the ribosomal subunits and usurping their function. A class of peptidomimetics [aminoglycoside-arginine conjugates (AAC)] has recently been designed to inhibit HIV TAR/tat interaction and in experiments aimed at assessing the inhibitory effects of AACs on TAR-containing transcripts, we found that AACs are general inhibitors of translation. Experiments reported herein aim at characterizing these novel properties of AACs. We find that AACs are inhibitors of eukaryotic and prokaryotic translation and exert their effects by blocking peptide chain elongation. Structure/activity relationship studies suggest that inhibition of translation by AACs is directly related to the number of arginine groups present on the aminoglycoside backbone and to the nature of the core aminoglycoside. AACs are therefore attractive tools for understanding and probing ribosome function.

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.
