Abstract
A furochromone, heterocarpin (1), was isolated from the halophyte Corydalis heterocarpa, along with four known compounds (2-5), which were obtained for the first time from this genus. The chemical structures of these compounds were determined by extensive 2-D NMR experiments and by comparison with the data reported in the literature. Compound 1 showed significant cytotoxic activities against four human cancer cells, AGS (human gastric cancer), HT-29 (human colon cancer), HT-1080 (human fibrosarcoma) and MCF-7 (human breast carcinoma). According to the cytotoxicity results, the mechanism behind the cytotoxic presence of compound 1 on AGS cells was investigated through the mRNA and protein levels of apoptotic pathway factors such as p21, p53, Bax, Bcl-2, XIAP, and caspases-3 and -9. The results indicated that heterocarpin (1) showed the cytotoxic effect on cancer cells by inducing apoptosis via regulated Bax-Bcl-2 ratio, overproduced caspases and suppressed XIAP. The inhibition of NFκB and activation of JNK and ERK pathways were also observed in the presence of heterocarpin (1). Therefore, heterocarpin and its source C. heterocarpa were suggested to be utilized as a functional food with potential pro-apoptotic activity against cancer cells.

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
