Abstract

fetched live from OpenAlex

A preliminary antiviral plate assay of the green solvent (hydro-ethanolic) shoot extract of Limonium densiflorum showed a potent activity against the herpes simplex virus type 1 (HSV-1). In order to isolate the active compounds, an in vitro bio-guided fractionation was undertaken by preparative chromatographic techniques. On the basis of nuclear magnetic resonance techniques, the structure of the isolated compounds was determined as gallic acid, epigallocatechin gallate, quercitrin, dihydrokaempferol, pinoresinol, N - trans- ferulolyl tyramine and (myricetin 3- O -α-rhamnopyranoside and myricetin 3- O -L-arabinofuranoside). Moreover, all isolated molecules were evaluated for their virucidality against HSV-1. Results showed that gallic acid and epigallocatechin gallate have strong activity, while pinoresinol and N - trans- ferulolyl tyramine have moderate activity. Whereas, the other molecules were inactive.

Teacher imitation

Not 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.
