Apexbio Technology LLC Metronidazole Benzoate 13182-89-3 10g

Metronidazole Benzoate (13182-89-3) is a small-molecule inhibitor targeting microbial DNA synthesis It is designed to inhibit nucleic acid synthesis processes thereby disrupting microbial cellular function Metronidazole Benzoate exerts its biological activity primarily through inhibition of nucleic acid synthesis and function within microbial cells In in vitro studies its efficacy is often quantified by IC50 values reflecting the concentration required to achieve half-maximal inhibition of microbial growth Based on these pharmacological properties Metronidazole Benzoate holds research potential in investigations of treatments for bacterial and protozoal infections
