Anti-tumor Mechanisms of Bruceine D： A Review / 中国实验方剂学杂志

ABSTRACT

Malignant tumors seriously threaten human life and health. Radiotherapy and chemotherapy are the conventional methods for the clinical treatment of advanced tumors. The prognosis and efficacy are still far from satisfactory due to the radiotherapy has serious adverse effects on the body and the chemotherapy often causes problems such as tumor resistance and cell proliferationinhibition. Therefore， the search for new， safe， and effective anti-tumor drugs and the elucidation of their molecular mechanisms are effective measures for clinical treatment of tumors and improvement of patients' quality of life. Active ingredients derived from Chinese herbal medicines and natural products have gradually become a hot spot in the research and development of anti-tumor drugs due to their multi-target and multi-channel anti-tumor pharmacological activity characteristics and their advantages such as less adverse reaction on the body. Bruceine D is a class of tetracyclic triterpenoids extracted from the fruit of the Chinese herbal medicine Bruceae Fructus， with anti-inflammatory， anti-malarial， anti-parasitic， and other pharmacological activities， and its anti-tumor activity is particularly significant. Pharmacological studies have found that bruceine D can regulate various cellular physiological activities such as proliferation， apoptosis， invasion， and migration of lung cancer， liver cancer， pancreatic cancer， intestinal cancer， and other cancer cells by targeting different signaling pathways. Bruceine D can be used in combination with other chemotherapeutic drugs to improve the sensitivity of tumor cells to chemotherapeutic drugs， thereby reducing the adverse effect of chemotherapy. Clinical application practice has shown that Bruceae Fructus oil emulsion injection containing bruceine D has significant advantages in the efficacy and safety of tumor treatment. Although there are many studies on the antitumor pharmacological activity of bruceine D and its clinical efficacy is significant， the specific antitumor molecular mechanism of bruceine D is still unclear， and there is a lack of systematic review on the existing antitumor mechanism of bruceine D. Therefore， based on the research on bruceine D in China and abroad in recent years， this paper reviewed the anti-tumor effect and related molecular mechanisms of bruceine D from six aspects， namely， tumor cell proliferation， apoptosis， metastasis and invasion， glucose metabolism process， autophagy， and chemotherapy sensitivity. This paper is expected to provide a pharmacological basis and scientific reference for the antitumor drug development and clinical application of bruceine D.
