At present, there are many antitumor drugs, but no ideal, highly effective and low toxic anti laryngeal cancer drugs have been found. Therefore, the study of effective, low toxicity, and even natural antitumor drugs to enrich the prevention and treatment of larynx cancer has become a focus and focus of many experts and scholars. Indole 3 - methanol (indole - 3 - carbinol) is a chemical prophylactic substance that can be extracted from cruciferous vegetables (such as broccoli, radish and cauliflower). Indole 3 methanol can inhibit the occurrence and development of many kinds of tumors.

Indole, N, N- two methyl formamide was used as raw material to synthesize indole -3- formaldehyde by Vilsmeier-Haack reaction. The yield of indole -3- formaldehyde was 87.1%. Then, the reaction system of toluene water was selected, potassium borohydride was used as a reductant, and the indole -3- methanol was reduced at 50~60 C. The reaction, extraction and recrystallization were completed at one time. 69%.

Inhibitory effect on the proliferation of laryngeal carcinoma cell 2 cells

The apoptosis rate of Hep 2 cells was (3.95 + 0.68)%, (8.54 + 1.35)%, (21.28 + 2.32)%, (38.65 + 4.85)% and (4.26 + 0.58)%, respectively (3.95 + 0.68)%, (8.54 + 1.35)%, (21.28 + 2.32)%, (3.95 + 0.68)%, respectively, after 4 concentrations of experimental group and control group. The results showed that indole -3- methanol inhibited proliferation of Livin cells in a concentration dependent manner, and induced apoptosis and protein expression. Indole -3- methanol inhibited the proliferation of Livin cells, and the induction of apoptosis might be related to the inhibition of the expression of the protein.

With the increase of the concentration of indole -3- methanol, the expression of Livin gradually decreased. The expression of Livin protein was negatively correlated with the apoptosis rate of human larynx cell line, suggesting that the Livin protein may play a role in the apoptosis of human larynx cancer cells induced by indole -3- methanol. Indole -3- methanol can only induce apoptosis of cancer cells, and is safe and non cytotoxic to non tumor cells. Indole -3- methanol can be used as a candidate for cancer prevention and treatment because of its high efficiency, non-toxic and natural anti-tumor properties. The molecular mechanism of indole -3- methanol inhibiting laryngeal cancer cells still needs further study in order to provide a theoretical basis for future clinical medication research.


The appropriate dose of indole-3-carbinol depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for indole-3-carbinol. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
