Abstract

An application of alginate sulfate in the preparation of drugs and health care products for preventing and treating diseases caused by human papillomavirus. Alginate sulfate has a strong dose-dependent inhibitory effect on HPV infection through experiments, and alginate sulfate inhibited the expression of E6 and E7 genes and proteins in HPV-transformed Hela and Caski cells in a dose-dependent manner. The alginate sulfate can be developed into a drug or a health care product against human papillomavirus by systematic scientific experiments, which will have a good market application prospect.
