[Research progress on effect of coumarins compounds in anti-tumor].

Coumarins are a group of important natural compounds, and have been found to have multi-biological activities such as anti-HIV, anti-tumor, anti-hypertension, anti-arrhythmia, anti-osteoporosis, assuaging pain, preventing asthma and antisepsis. One of which is its anti-tumor effect and that is a research focus on. Therefore, we believe that it is necessaryto carry out further studies on the effect of coumarins compounds in anti-tumor. Investigation should emphasize on improving techniques for extraction and separation, searching the effective precursory compound, and synthesizing and screening out courmarin derivatives with high activity and low toxicity. Here the recent research progress in anti-tumor effect of coumarins compounds is reviewed.
