[Progress of studies on anti-breast tumor mechanism of alkaloids].

Breast tumor has become one of the malignant tumors with the highest incidence, and is a serious threat to human health, especially to women. Chemotherapy is an important anti-breast tumor therapy, which can be used in almost every stage of breast tumor therapy alone or in the combination with surgery and radiation therapy. Alkaloids are a kind of ubiquitous natural products, and important active components of various medicinal plants. A large number of studies have shown that alkaloids could exert an anti-breast tumor effect by inhibiting proliferation, metastasis and angiogenesis, resisting mitosis, promoting apoptosis and autophagy, and triggering cell cycle arrest. The extensive anti-breast tumor effect makes alkaloids an important candidate drug source. This paper reviews the anti-breast tumor mechanism of natural products of alkaloids.
