Abstract
Although natural products have played a crucial role in drug discovery, limited accessibility and difficult synthesis restrict their use as leads. Tetrahydroquinoline is an essential structural feature in many natural and synthetic compounds with notable biological properties. This article covers the distribution of tetrahydroquinoline alkaloids in different organisms and their potential as a source of new bioactive natural products. These alkaloids are produced through various biosynthetic pathways, resulting in diverse structures and bioactivities. While some tetrahydroquinolines have therapeutic potential, their toxicity against predators and pathogens presents challenges for drug development. Despite their significance, tetrahydroquinolines have not been thoroughly covered in review literature, making this article essential for discussing their natural occurrence, biosynthetic pathways, and biological activities from 2011 to mid-2023.

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
