In Vitro

Sparfloxacin (CI-978) shows broad and potent antibacterial activity. Its MICs for 90% of the strains tested are 0.1 to 0.78 μg/ml against gram-positive organisms, such as members of the genera Staphylococcus , Streptococcus and Enterococcus , and 0.0125 to 1.56 μg/ml against gram-negative organisms, such as members of the family Enterobacteriaceae and the genera Pseudomona . Its MICs are 0.025 to 0.78 μg/ml against glucose nonfermenters, 0.2 to 0.78 μg/ml against anaerobes, 0.0125 to 0.05 μg/ml against Legionella. Sparfloxacin (CI-978) showed good oral efficacy against systemic infections with Staphylococcus aureus , Streptococcus pyogenes , Streptococcus pneumoniae , Escherichia coli , and Pseudomonas aeruginosa in mice^[1]. Sparfloxacin targets DNA gyrase and inhibits DNA synthesis^[2].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
