Antibacterial activity of gemini quaternary ammonium salts.
A series of gemini quaternary ammonium salts (chlorides and bromides), with various hydrocarbon chain and spacer lengths, were tested. These compounds exhibited antibacterial activity against both Gram-positive and Gram-negative bacteria and were not mutagenic. The strongest antibacterial effect was observed for TMPG-10 Cl (against Pseudomonas aeruginosa ATCC 27853) and TMPG-12 Br (against Stap...
متن کاملSynthesis and Antibacterial Activity of Quaternary Ammonium 4-Deoxypyridoxine Derivatives
A series of novel quaternary ammonium 4-deoxypyridoxine derivatives was synthesized. Two compounds demonstrated excellent activity against a panel of Gram-positive methicillin-resistant S. aureus strains with MICs in the range of 0.5-2 μg/mL, exceeding the activity of miramistin. At the same time, both compounds were inactive against the Gram-negative E. coli and P. aeruginosa strains. Cytotoxi...
متن کاملAntibacterial Activity of Alanine-Derived Gemini Quaternary Ammonium Compounds
The antibacterial activity of alanine-derived gemini quaternary ammonium salts (chlorides and bromides) with various spacer and alkyl chain lengths was investigated. The studied compounds exhibited a strong bactericidal effect, especially bromides with 10 and 12 carbon alkyl chains and 3 carbon spacer groups (TMPAL-10 Br and TMPAL-12 Br), with a short contact time. Both salts dislodged biofilms...
متن کاملAntibacterial activity of bone cement containing quaternary ammonium polyethyleneimine nanoparticles.
Sir, A bone cement mantle is commonly used in orthopaedic surgery, and creates an ideal environment for bacterial growth. Bacterial infection following joint replacement surgery is a catastrophic complication. It is estimated that infections occur in up to about 2% of primary hip and knee replacements, whereas revision surgery carries a 2–3-fold higher risk. The most common bacteria isolated fr...
متن کاملSynthesis and antibacterial activity of quaternary ammonium salt-type antibacterial agents with a phosphate group.
Quaternary ammonium salts are frequently used as antibacterial agent that disrupts cell membrane through the binding of their ammonium cations to anionic sites in the outer layer tissue of bacteria. This article describes the synthesis of quaternary ammonium salt-type antibacterial agents with a phosphate group that strongly binds to hydroxyapatite and bromide ion as counterion. Evaluation of t...
