Synthetic antibacterial agents are being actively researched both domestically and internationally, and the results have brought ground-breaking progress to the clinical field, and are effective against all kinds of infections, not just urinary tract infections. It has been shown that It is also known that its mechanism of action is the inhibition of DNA gyrase, which is a DNA steric enzyme, and that transmission of resistance by plasmids such as antibiotics does not occur. However, it is difficult to say that synthetic antibacterial agents are perfect drugs, and the emergence of new antibacterial agents is strongly desired due to their usefulness.
