This product can selectively inhibit the microRNA virus polymerase of infected cells, and inhibit the synthesis of viral RNA by inhibiting the RNA polymerase that depends on the virus code in the infected cells, thereby inhibiting the virus. In tissue culture, 50mu;g/ml can effectively inhibit various strains of human enterovirus, Coxsackie virus and polio virus; 10mu;g/ml can inhibit acute epidemic hemorrhagic tuberculosis and keratitis (commonly known as pink eye) virus (Shanghai-17 strain) (a microRNA virus).

This product is a semi-synthetic tetracycline broad-spectrum antibiotic with high efficiency and long-lasting effect. Among tetracycline antibiotics, this product has the strongest antibacterial effect. The antibacterial spectrum is similar to that of tetracycline. It has a strong effect on Gram-positive bacteria including tetracycline-resistant Staphylococcus aureus, Streptococcus, and gram-negative bacteria such as Neisseria gonorrhoeae; the effect on Gram-negative bacilli is generally weaker; this product also has a good inhibitory effect on Chlamydia trachomatis and Ureaplasma urealyticum. In recent years, due to the abuse of tetracycline antibiotics, most common Gram-positive and Gram-negative bacteria are now resistant to this product. The mechanism of action of this product is to bind to the A position of the 30S subunit of the ribosome, prevent the extension of the peptide chain, and thus inhibit the protein synthesis of bacteria or other pathogenic microorganisms. This product is an antibacterial drug, but at high concentrations, it also has a bactericidal effect.

This product is a glucocorticoid drug. It has anti-inflammatory and anti-allergic effects.

Has anti-inflammatory and anti-allergic effects

It has high antibacterial activity against common aerobic Gram-positive bacteria, such as Staphylococcus aureus (including those resistant to penicillin G), Staphylococcus epidermidis, β-hemolytic Streptococcus, viridans Streptococcus and Streptococcus pneumoniae. It has good antibacterial effect on anaerobic bacteria, including Clostridium diphtheriae, and Clostridium perfringens. It has no activity against Gram-negative bacteria such as Enterococcus, meningococci, Neisseria gonorrhoeae, and Haemophilus influenzae, as well as fungi. There is no cross-resistance with penicillin, chloramphenicol, cephalosporins and tetracyclines, and there is partial cross-resistance with macrolides. It acts on the 50S subunit of the ribosome of sensitive bacteria, preventing the extension of the peptide chain, thereby inhibiting the protein synthesis of bacterial cells. It is generally an antibacterial agent and has a bactericidal effect on certain bacteria at high concentrations.
