Biological Activity

Description Cefdinir (FK 482, PD 134393, CI-983) is an oral cephalosporin antibiotic, used to treat bacterial infections in many different parts of the body.
In vitro
In vitro Cefdinir, a new oral 2-amino-5-thiazolyl cephalosporin, inhibits the luminol-amplified chemiluminescence (LACL) response of human neutrophils stimulated by PMA but not opsonized zymosan, in a concentration-dependent but not time-dependent manner. Cefdinir inhibits LACL generation in cell-free systems consisting of H2O2, NaI, and either horseradish peroxidase or amyeloperoxidase-containing neutrophil extract. Cefdinir impairs LACL response induced by the calcium ionophore A23187 and FMLP, and this impairment is increased in cytochalasin B-treated neutrophils. Cefdinir directly inhibits the activity of myeloperoxidase-containing neutrophil extract released into the extracellular medium during neutrophil stimulation by soluble mediators, but has no effect on that released into the phagolysosome during phagocytosis. [1] Cefdinir demonstrates excellent activity against a wide range of gram-positive and gram-negative bacteria. Cefdinir is resistant to a broad variety of β-lactamases and exhibits a β-lactam stability profile generally better than those observed with cefaclor and cefuroxime. Cefdinir elimination is primarily mediated by the kidney. Cefdinir interacts with the dipeptide transporters PEPT1 and PEPT2. Cefdinir tubular reabsorption is substantial, that Cefdinir tubular secretion is inhibitable by probenecid, and that this secretion is probably mediated by the renal organic anion secretory pathway.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
