Moreover, during preclinical studies hexadecylphosphocholine (He-PC) found to be highly effective in inhibiting the growth of chemically induced rat mammary carcinomas, and even a high percentage of the tumors regressed completely. The He-PC has many more applications such as antifungal agent, antiprotozoal drug, protein kinase inhibitor or immunomodulator.
