Sparfloxacin. Following an oral loading dose of 400 mg followed by 200 mg daily, mean concentrations of sparfloxacin (2.5 to 5 h after dosing) in bronchial mucosa, epithelial lining fluid and alveolar macrophages are 4.4 … Phosphine derivatives of sparfloxacin – Synthesis, structures and in vitro activity Author links open overlay panel Urszula K. Komarnicka a Radosław Starosta a Katarzyna Guz-Regner b Gabriela Bugla-Płoskońska b Agnieszka Kyzioł c Małgorzata Jeżowska-Bojczuk a *Salivary concentrations are 66 to 70% of plasma levels, while CSF penetration appears to be somewhat limited with CSF:plasma concentration ratios of only 0.25 to 0.35. ( 1993) has summarized many of the studies published in Japanese regarding the tissue distribution of sparfloxacin. It was patented in 1985 and approved for medical use in 1993.The compound is indicated for treating community-acquired lower respiratory tract infections (Sparfloxacin is about 37-45% bound to proteins in the Shimada et al. Sparfloxacin achieves high concentrations in respiratory and sinus tissues. Sparfloxacin is a highly potent fluoroquinolone against a wide range of gram-positive and gram-negative bacteria, anaerobes, Legionella spp., Mycoplasma spp., Chlamydia spp. Sparfloxacin-Metal Complexes as Urease Inhibitors: Their Synthesis, Characterization, Antimicrobial, and Antienzymatic Evaluation Somia Gul , 1 Najma Sultana , 2 M.

In vivo: Sparfloxacin showed good oral efficacy against systemic infections with Staphylococcus aureus , Streptococcus pyogenes , Streptococcus pneumoniae , Escherichia coli , and Pseudomonas aeruginosa in mice. In rabbits, sparfloxacin achieves very good penetration into the ocular vitreous (54%), cornea (76%) and lens (36%).C[C@@H]1CN(C[C@@H](N1)C)c2c(c(c3c(c2F)n(cc(c3=O)C(=O)O)C4CC4)N)FInChI=1S/C19H22F2N4O3/c1-8-5-24(6-9(2)23-8)17-13(20)15(22)12-16(14(17)21)25(10-3-4-10)7-11(18(12)26)19(27)28/h7-10,23H,3-6,22H2,1-2H3,(H,27,28)/t8-,9+ Synthesis of diorganotin(IV) complexes of sparfloxacin by sodium salt method A solution of sparfloxacin ( HL ) (1.0 mM, 0.392 g) in 15 ml of specially dried methanol was added to sodium methoxide solution which was prepared by reacting sodium (1.0 mM, 1.1 eq) in 15 ml of dry methanol. Synthesis and characterization of new diorganotin(IV) complexes of sparfloxacin are reported.FT-IR, NMR and UV–Vis spectrum were recorded and compared with theoretical results.Geometrical parameters, atomic charges, MEP and frontier MO's have been explained.Conceptual-DFT based global reactivity descriptors for the studied system were calculated.New diorganotin(IV) derivatives of sparfloxacin having general formula RWe use cookies to help provide and enhance our service and tailor content and ads. Sparfloxacin exerts its antibacterial activity by inhibiting DNA gyrase, a bacterial topoisomerase. and Mycobacteria spp., including multiresistant strains 12, 15, 16.The elimination half-life (t 1/2) is approximately 15–20 h which allows once daily administration. Sparfloxacin (Zagam) is used to study antimicrobial activity against Mycobacteria and has been shown to have photosensitizing effects. Sparfloxacin has in vitro activity against a wide range of gram-negative and gram-positive microorganisms. Sparfloxacin is a synthetic fluoroquinolone broad-spectrum antimicrobial agent in the same class as ofloxacin and norfloxacin.
