Methyl 5-MeO-<i>N</i>-aminoanthranilate, a minimalist fluorogenic probe for sensing cellular aldehydic load
Bibliographic record
Abstract
Methyl 5-MeO-N-aminoanthranilate, a fluorogenic probe comprising a single substituted benzene ring has been applied towards the fluorescence detection of endogenous carbonyls through rapid, catalyst-free complexation of these bio-derived markers of cell stress under physiological conditions. The products formed during the reaction between the probe and aldehydic products of lipid peroxidation, including malondialdehyde and long-chain aliphatic aldehydes relevant to the oxidative decomposition of cell membranes, have been evaluated. Live cell imaging of diethyl maleate-induced oxidative stress with or without pretreatment with α-tocopherol was carried out, with the result suggesting that the presented molecule might serve as a minimalist molecular probe capable of cellular "Aldehydic Load" detection by fluorescence microscopy. This work also outlines functional constraints of the fluorogenic probe (i.e. intramolecular cyclization), providing a realistic evaluation of methyl 5-MeO-N-aminoanthranilate for fluorescence-based aldehyde detection.

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.
