Abstract

The invention provides novel use of 24-acetyl alisol F (ALI). The 24-acetyl alisol F can be used for increasing the cumulant of adriamycin (DOX) in cells to promote adriamycin to enter into nucleus so as to remarkably promote early apoptosis of an MCF-7 / ADR cell (human breast cancer-adriamycin-resistant cells). The 24-acetyl alisol F has an important medical development value in preparing anti-tumor drugs. Due to the action of the 24-acetyl alisol F, the composition prepared from the 24-acetyl alisol F and adriamycin can be used for effectively increasing the sensitivity of the anticancer drug adriamycin and further reducing the side effects of existing chemotherapeutical drugs while improving the chemotherapeutical effect.

Description

technical field [0001] The present invention relates to the new application of proterpene type tetracyclic triterpenes, especially the new application of 24-acetyl alisol F. Background technique [0002] Chemotherapy is a main means of tumor treatment, but the phenomenon of drug resistance of tumor cells is unavoidable, which is the main obstacle of tumor chemotherapy, and also the main reason for the poor effect or even failure of chemotherapy. [0003] Clinically, many chemotherapeutic drugs can achieve good results in the initial treatment of tumors, but they will relapse after a period of time, and the therapeutic effect after recurrence is poor. The main reason is that tumor cells develop resistance to chemotherapeutic drugs. It is estimated that drug resistance exists in more than 90% of cancer deaths. Therefore, the study of tumor drug resistance is of equal importance to the study of treatment methods. [0004] There are many factors that lead to drug resistance of...
