It has strong dispersing and emulsifying properties, increases the negative charge on the surface of red blood cells, enhances mutual repulsion, resists adhesion between red blood cells or between red blood cells and blood vessel walls, reduces blood viscosity, anti-coagulation (efficacy equivalent to 1/3-1/2 of heparin), lowers blood lipids, dilates blood vessels, lowers blood pressure and blood sugar.

This product can inhibit viral DNA and RNA polymerase, thereby inhibiting viral reproduction. On human embryonic kidney cells, 1% concentration has a significant inhibitory effect on DNA viruses (adenovirus, herpes virus) and RNA viruses (echovirus), and has an inhibitory effect on all stages of the viral proliferation cycle. It has no direct effect on free viral particles.

It is converted into pyridoxal phosphate in red blood cells and acts as a coenzyme in various metabolic functions of proteins, carbohydrates, and lipids. It is also involved in the conversion of tryptophan into niacin or 5-hydroxytryptamine.

Vitamin B6 is converted into pyridoxal phosphate in red blood cells and acts as a coenzyme in various metabolic functions of proteins, carbohydrates, and lipids. Vitamin B6 is also involved in the conversion of tryptophan into niacin or 5-hydroxytryptamine.

Antiviral drug. It has an inhibitory effect on herpes simplex virus, varicella zoster virus, cytomegalovirus, etc. in vitro. After entering the cells infected by herpes virus, this product competes with deoxynucleoside for viral thymidine kinase or cell kinase, and the drug is phosphorylated into activated acyclovir triphosphate, and then inhibits viral replication in two ways: ① Interfering with viral DNA polymerase and inhibiting viral replication; ② Under the action of DNA polymerase, it binds to the growing DNA chain, causing the extension of the DNA chain to be interrupted. This product has a special affinity for viruses, but has low toxicity to mammalian host cells.

This product is a macrolide antibiotic. Its mechanism of action is similar to that of erythromycin, and its antibacterial spectrum is also similar to that of erythromycin, but its antibacterial activity against most Gram-positive bacteria is slightly worse. Some erythromycin-resistant Staphylococcus aureus are still sensitive to kitasamycin. This product also has considerable activity against diphtheria, tetani, Neisseria gonorrhoeae, pertussis, Rickettsia and Chlamydia trachomatis.
