Abstract
The anthocyanins, coumarins, and casearins are interesting compounds due to their chemical and biological properties. In the present study, the in vitro effect of 4 ́-O-methyl-gallocatechin (an anthocyanin), columbianatin (a coumarin), and casearin G on the mitogenic response and phagocytic activity from whole blood cells, was evaluated. In addition, the cytotoxic effect of these compounds on the cell lines B16/BL6 (murine melanoma) and COS-7 (kidney fibroblasts transfected with SV40 virus) was measured by a colorimetric assay (MTS/PMS, IC50: inhibitory concentration) and the sulphorhodamine B assay (GI50: growth inhibition, TGI: total growth inhibition, LC50: lethal concentration). The results show that 4 ́-O-methyl-gallocatechin and columbianatin reduced lymphoproliferation. Columbianatin reduced both the phagocytic index and the percentage of phagocytic monocytes/macrophages. Casearin G showed both cytotoxic (IC50, LC50) and cytostatic (GI50) effects against the tumor cells, B16/BL6 (IC50 = 30.8 μM; GI50 = 12.4 μM; LC50 = 34.7 μM) and COS-7 (IC50 = 137.3 μM; GI50 = 3.8 μM; LC50 = 29.9 μM). In conclusion, 4 ́-O-methyl-gallocatechin and columbianatin showed immunosuppressive properties in vitro while casearin G was the most cytotoxic.

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
