Evaluation and Mechanistic Investigation of Antitumor Compounds from Dioscorea nipponica Makino subsp. rosthornii Through Spectrum-Effect Relationship Analysis
To screen potential antitumor compounds from Dioscorea nipponica Makino subsp. rosthornii, validate them in cellular models, and investigate their mechanisms of action in inhibiting proliferation in A549 cells.
Key Findings:
Identified 23 distinct chemical constituents in D. nipponica Makino subsp. rosthornii.
Extract significantly inhibited proliferation, migration, and invasion of A549 cells.
Three potential antitumor compounds were identified: protodioscin, diosgenin, and gracillin.
Saponins inhibited A549 cell malignant phenotype by reducing N-cadherin and MMP2, while enhancing E-cadherin expression.
Interpretation:
The study provides evidence that specific saponins from D. nipponica Makino subsp. rosthornii can effectively inhibit lung cancer cell proliferation and metastasis through modulation of key proteins involved in cancer progression.
Limitations:
The study was limited to in vitro models; further in vivo studies are needed.
The chemical profile may vary based on geographical origin and environmental factors.
Conclusion:
Dioscorea nipponica Makino subsp. rosthornii contains active constituents with significant antitumor effects, supporting its potential application in cancer therapy.
