Abstract:
Three cancer cell lines including gastric cancer SGC-7901, HGC-27, and MGC-803 cells were employed to evaluate the bioactivity of seven Dendrobium species. Simultaneously, these Dendrobium species were assessed with UPLC-Q-TOF-MS, and 504 common peaks were found. Based on the hypothesis that biological effects varied with differences in components, multivariate relevance analysis for chemical component-activity relationship of Dendrobium, including grey relation(GRA) and partial least squares(PLS) analysis were performed to evaluate the contribution of each identified component. The target peaks were identified by standards toge-ther with databases of Dendrobium, Nature Chemistry, MassBank, etc. Finally, four active components, including 3,5,9-trihydroxy-23-methylergosta-7,22-dien-6-one, diacylglycerol(14∶1/22∶6/0∶0), pipercitine, and 22-tricosenoic acid, might have negative effect on the growth of gastric cancer cells.
Insights
This study investigated the anti-gastric cancer potential of seven Dendrobium species. Four compounds were identified as potentially inhibiting gastric cancer cell growth, offering new therapeutic leads.
Area of Science:
- Phytochemistry
- Pharmacology
- Cancer Research
Background:
- Dendrobium species are traditionally used in medicine.
- Gastric cancer remains a significant global health challenge.
- Understanding the chemical constituents and bioactivity of Dendrobium is crucial for therapeutic development.
Purpose of the Study:
- To evaluate the bioactivity of seven Dendrobium species against gastric cancer cell lines.
- To identify active chemical components responsible for the observed bioactivity.
- To establish a chemical component-activity relationship using multivariate analysis.
Main Methods:
- Utilized three human gastric cancer cell lines (SGC-7901, HGC-27, MGC-803).
- Employed Ultra-Performance Liquid Chromatography-Quadrupole Time-of-Flight Mass Spectrometry (UPLC-Q-TOF-MS) for chemical profiling.
- Performed multivariate relevance analyses, including Grey Relation Analysis (GRA) and Partial Least Squares (PLS), to link chemical components to bioactivity.
Main Results:
- Identified 504 common peaks across the seven Dendrobium species.
- Four compounds, 3,5,9-trihydroxy-23-methylergosta-7,22-dien-6-one, diacylglycerol(14∶1/22∶6/0∶0), pipercitine, and 22-tricosenoic acid, were identified as potentially active.
- These compounds demonstrated a negative effect on the proliferation of gastric cancer cells.
Conclusions:
- The study successfully linked specific chemical components of Dendrobium to anti-gastric cancer activity.
- Identified compounds represent potential novel therapeutic agents for gastric cancer treatment.
- Further research is warranted to elucidate the precise mechanisms of action and optimize these compounds for clinical application.
