چکیده
The asymmetric unit of the title compound, C19H23FN3O3 (+)·Cl(-)·2H2O [systematic name: 4-(3-carb-oxy-1-cyclo-propyl-6-fluoro-4-oxo-1,4-di-hydro-quin-o-lin-7-yl)-1-ethyl-piperazin-1-ium chloride dihydrate], consists of two independent monocations of the protonated enrofloxacin, two chloride anions and four water mol-ecules. In the cations, the piperazinium rings adopt chair conformations and the dihedral angles between the cyclo-propyl ring and the 10-membered quinoline ring system are 56.55 (2) and 51.11 (2)°. An intra-molecular O-H⋯O hydrogen bond is observed in each cation. In the crystal, the components are connected via O-H⋯Cl, N-H⋯Cl and O-H⋯O hydrogen bonds, and a π-π inter-action between the benzene rings [centroid-centroid distance = 3.6726 (13) Å], resulting in a three-dimensional array.

متن کاملPharmacokinetic interactions of flunixin meglumine and enrofloxacin in ICR mice.
We examined the pharmacokinetic interactions of enrofloxacin and flunixin in male ICR mice that were subcutaneously (SC) administered with both or either one of the drugs. The experiments were performed on the following three groups: flunixin alone (2 mg/kg, SC), combination of flunixin (2 mg/kg, SC) and enrofloxacin (10 mg/kg, SC), and enrofloxacin alone (10 mg/kg, SC). Blood samples were coll...
متن کاملEffects of enrofloxacin on porcine phagocytic function.
The interaction between enrofloxacin and porcine phagocytes was studied with clinically relevant concentrations of enrofloxacin. Enrofloxacin accumulated in phagocytes, with cellular concentration/extracellular concentration ratios of 9 for polymorphonuclear leukocytes (PMNs) and 5 for alveolar macrophages (AMs). Cells with accumulated enrofloxacin brought into enrofloxacin-free medium released...
متن کاملTherapeutic efficacy of bacteriophage and Baytril (enrofloxacin) individually and in combination to treat colibacillosis in broilers.
A study was conducted to evaluate the therapeutic efficacy of bacteriophage and the antibiotic enrofloxacin individually and in combination to treat colibacillosis. The experimental design was a 2 x 2 x 2 factorial with 8 treatments and 4 replicate pens of 10 birds. The treatments were 1) control, 2) unchallenged birds treated with bacteriophage, 3) enrofloxacin, or 4) the combination; 5) birds...
متن کاملInfluence of porcine Actinobacillus pleuropneumoniae infection and dexamethasone on the pharmacokinetic parameters of enrofloxacin.
The impact of Actinobacillus pleuropneumoniae (APP) infection in swine on the pharmacokinetic parameters of enrofloxacin were determined. Twenty-four animals were used in a 2 x 2 factorial of treatment groups (six animals per group) to determine the impact of APP-induced inflammation and the anti-inflammatory drug dexamethasone on enrofloxacin pharmacokinetic parameters. All animals received en...
