Bibliographic record
Abstract
Molecular modification of compounds remains important strategy towards the discovery of new drugs. In this sense, this study presents a new pyrazole derivative 5-(1-(2-fluorophenyl)-1 H-pyrazol-4-yl)-1 H-tetrazole (LQFM039) and evaluated the anti-inflammatory, analgesic, and vasorelaxant effects of this compound as well the mechanisms of action involved in the pharmacological effects. For this, mice were orally treated with LQFM039 (17.5, 35, or 70 mg/kg) prior acetic acid-induced abdominal writhing, formalin, tail flick, and carrageenan-induced paw edema protocols. In addition, vascular reactivity protocols were made with aortic rings contraction with phenylephrine and stimulated with graded concentrations of LQFM039. Abdominal writhing and licking time in both neurogenic and inflammatory phases of formalin were reduced with LQFM039 without altering latency to nociceptive response in the tail flick test. Carrageenan-induced paw edema showed that LQFM039 reduces edema and cell migration. In addition, the mechanism of action of LQFM039 involves NO/cGMP pathway and calcium channels, since this new pyrazole derivate elicited concentration-dependent relaxation attenuated by Nω-nitro-l-arginine methyl ester and 1 H-[1,2,4] oxadiazolo [4,3-alpha]quinoxalin-1-one, and blockade of CaCl 2 -induced contraction. Altogether, our finding suggests anti-inflammatory, antinociceptive, and vasorelaxant effect of this new pyrazole derivative with involvement of NO/cGMP pathway and calcium channels.

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.
