In vivo test, it has a certain inhibitory effect on Ehrlich ascites carcinoma, sarcoma-180 and solid type of liver cancer. It can increase the respiratory control rate of mitochondria and lysosomal enzyme activity of ascites H22 liver cancer cells, and interfere with the division and resistance of cancer cells. Broken down to M phase and affecting its cycle speed. This product can destroy the cancer cell skeleton (microfilaments, microtubules), affect the ultrastructure of cancer cells, resulting in mitochondria, microvilli and plasma membrane damage. It can inhibit DNA synthesis of cancer cells, but it does not inhibit normal bone marrow cells and can increase leukocytes.
