Problems solved by technology

However, it is unclear whether ginsenoside Rg3 can reverse drug resistance in BRAF(V600E) mutant tumor cells
[0016] At present, there are no reports at home and abroad on whether the natural products parthenolide, luteolin, eriodinium, and ginsenoside Rg3 can reverse the resistance of tumor cells to BRAF (V600E) inhibitors

Abstract

The invention provides novel application of parthenolide, luteolin, chrysoeriol and ginsenoside Rg3, and specifically relates to preparation of the compounds or derivatives of the compounds in preparation of drugs for preventing and / or treating drug-resistant BRAF (V600E) mutant-type tumors. It is found that proliferation of tumor cells resistant to BRAF (V600E)-targeted drugs can be inhibited through parthenolide, luteolin, chrysoeriol and ginsenoside Rg3, the tumor cells include inherent and acquired tolerant tumor cells, and growth of tumors is inhibited. It is shown through results that parthenolide, luteolin, chrysoeriol and ginsenoside Rg3 have the potential to be developed as the safe and effective drugs for treating the drug-resistant BRAF (V600E) mutant-type tumors.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to the application of natural products parthenolide, luteolin, erioidin and ginsenoside Rg3 in the preparation of drugs for preventing and / or treating drug-resistant BRAF (V600E) mutant tumors. Background technique [0002] Mitogen-activated protein kinases (MAPKs) are key signaling pathways in many cancers. BRAF is an important signaling molecule in the MAPK pathway. The BRAF mutation was first described in 2002, with V600E (valine at position 600 replaced by glutamic acid) being its most common mutation. According to reports, in papillary thyroid carcinoma (60.83%), hairy cell leukemia (58.33%), melanoma (48%), anaplastic thyroid carcinoma (35.96%), serous ovarian cancer (35%), breast cancer (13%) %), colorectal cancer (8.04%), glioma (6.5%), non-small cell lung cancer (3%) and other tumors exist BRAF (V600E) mutation. This mutation leads to persistent activation of BRAF, wh...
