Antofloxacin

Antofloxacin is a well tolerate, orally active and broad-spectrum 8-amino-fluoroquinolone with potent antibacterial activities. Antofloxacin shows superior antibacterial activity against gyrA mutation-positive H. pylori strains, especially in Asn87- mutated strains, compared to levofloxacin. Antofloxacin is a weak, reversible inhibitor of CYP1A2 for the research of infections caused by a diverse group of bacterial species.

In Vivo

Antofloxacin (2.5~160 mg/kg; s.c.; 24 hours) penetration ratio ranges from 1.22 to 1.54 for the total drug concentrations and is independent of the dose levels^[3]. Antofloxacin increases the plasma theophylline concentration, partly by acting as a mechanism based inhibitor of CYP1A2. Antofloxacin inhibits the formation of the three metabolites of theophylline was time-, concentration- and NADPH-dependent, which is characteristic of mechanism-based inhibition^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
