Design, Synthesis, and Biological Evaluation of Triazole-Linked Lignan–Monoterpenoid-Based Hybrid Molecules as Xanthine Oxidase Inhibitors with Potent In Vivo Efficacy
Bibliographic record
Abstract
A novel series of triazole-tethered monoterpenoid–lignan hybrid molecules has been designed to target xanthine oxidase (XO), the enzyme responsible for hyperuricemia when it is up-regulated, resulting in gout and other metabolic disorders. Designed molecules were synthesized and initially evaluated for their XO inhibitory potential, and MT7 was most active (XO: IC 50 = 0.263 ± 0.06 μM) with radical scavenging efficacy. MT7 showed higher cytotoxic potential against XO harboring cancer cells (MBDA-MB-231 breast cancer cells) than non-XO-harboring cells (A547 skin cancer cells), confirming intracellular XO inhibition. MT7 was nontoxic to mouse fibroblast cells (L929) and had favorable pharmacokinetic profiles. In vivo investigations in rodent-based animal models revealed the LD 50 (300 mg/kg) value of MT7 and a dose-dependent reduction in serum uric acid. Overall, this suggests MT7 as an effective lead molecule for further investigations as a potential clinical candidate for the management of hyperuricemia via XO inhibition.

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.
