Nucleoside antiviral drugs. After entering the cell, this product is rapidly phosphorylated to a monophosphate compound, and then becomes a triphosphate compound through the action of cellular kinase. Its phosphorylation in cells infected with cytomegalovirus is faster than that in normal cells. Ganciclovir can competitively inhibit DNA polymerase and incorporate into the DNA of viruses and host cells, thereby inhibiting DNA synthesis. This product has a stronger inhibitory effect on viral DNA polymerase than host cell polymerase. In animal experiments, this product has teratogenic, carcinogenic, immunosuppressive effects and reproductive system toxicity.

Inhibits the demethylation of 14α-sterol mediated by cytochrome P450 in fungi, thereby inhibiting the biosynthesis of ergosterol. It has antibacterial effects on Candida, Aspergillus, Actinomyces, Fusarium, etc.

It can enhance cellular immunity and regulate immune balance, transform stem cells produced by bone marrow into T lymphocytes, enhance cellular immunity, and have little effect on humoral immunity. It is used to treat cellular immunity deficiency diseases, such as thymic hypoplasia, severe mixed immunodeficiency, ataxia telangiectasia, leprosy, severe infection, recurrent oral ulcers, etc., in patients with low cellular immunity. It can also be used for viral hepatitis, malignant tumors and anti-aging.

This product is a polypeptide hormone extracted from calf or pig thymus peptides. It has the functions of enhancing cellular immunity and regulating immune balance. Thymosin can transform stem cells produced by bone marrow into T lymphocytes, thereby enhancing cellular immunity and having little effect on humoral immunity. Thymosin is used to treat cellular immune deficiency diseases, such as thymic hypoplasia, severe mixed immunodeficiency, ataxia telangiectasia, leprosy, severe infection, recurrent oral ulcers, etc., for patients with low cellular immunity. It can also be used for viral hepatitis, malignant tumors and anti-aging.

It works synergistically with thymosin α1 to enhance cellular immune function and regulate immune balance.
