Triptolide
-
Cancers mentioned: Ovarian cancer and general solid tumors.
-
Food Occurrences: Derived from the Thunder God Vine (Tripterygium wilfordii). It is a medicinal herb and is not found in conventional foods; it must be handled with care due to potential toxicity if not properly formulated.
-
Summary of the Topic: Triptolide is a diterpene trioxide that is extremely potent even at low concentrations. It is known for its ability to induce rapid apoptosis by inhibiting transcriptional regulators and heat shock proteins (HSP27 and HSP70), which cancer cells use to survive stress.
-
Because of its high toxicity to healthy cells in its raw form, modern oncology research focuses on creating synthetic derivatives and nano-formulations that target the drug specifically to the tumor site. Its ability to overcome broad-spectrum drug resistance makes it a highly valuable candidate for advanced-stage ovarian cancers.
-
Remainder of Report & Sources:
-
Mechanisms: Pro-apoptotic effects, inhibition of HSP proteins, and suppression of tumor immunity evasion.
-
Combinations: Often combined with curcumin to promote apoptosis in ovarian cancer cells.
-
Primary Source: Cui et al., Chinese Medicine, 2025
-
-
Primary Food Sources: Thunder God Vine (Tripterygium wilfordii).
-
Molecular Targets: Physically binds to XPB, a subunit of the TFIIH transcription factor, effectively “shutting down” the cancer cell’s ability to transcribe DNA into RNA. It is perhaps the most potent compound on this list but carries the highest toxicity profile.
-
Bioavailability: Higher than polyphenols, but limited by a narrow therapeutic window (the dose for benefit is close to the dose for toxicity).
-
Cross-Links:
-
Curcumin: Significantly promotes apoptosis in Ovarian Cancer by downregulating heat shock proteins (HSP27 and HSP70).
