Oxacillin sodium salt monohydrate CAS:7240-38-2
Oxacillin sodium salt monohydrate is a narrow-spectrum beta-lactam antibiotic, similar to oxacillin sodium salt, with the addition of one water molecule in its crystal structure. Structurally resembling methicillin and nafcillin, it is effective against penicillinase-producing staphylococci. Oxacillin sodium salt monohydrate inhibits bacterial cell wall synthesis by interfering with peptidoglycan cross-linking, exerting bactericidal effects against susceptible organisms. Available in injectable formulations for intravenous or intramuscular administration, it is commonly used in healthcare settings for treating infections caused by penicillinase-producing Staphylococcus aureus strains.
-
Pefloxacin mesylate CAS:70458-95-6
Pefloxacin mesylate is a synthetic fluoroquinolone antibiotic with broad-spectrum antibacterial activity against both gram-positive and gram-negative bacteria. It functions by inhibiting bacterial DNA synthesis through its interaction with enzymes like DNA gyrase and topoisomerase IV, leading to bactericidal effects. Pefloxacin mesylate is available in various pharmaceutical formulations for oral and injectable administration, offering effective treatment options for a wide range of bacterial infections.
-
Novobiocin sodium salt CAS:1476-53-5
Novobiocin sodium salt is a microbial-derived antibiotic belonging to the coumarin family, originally isolated from Streptomyces strains. It exhibits broad-spectrum antibacterial activity, particularly against gram-positive bacteria, by inhibiting DNA gyrase, an essential enzyme involved in DNA replication and transcription. Novobiocin is commonly used in microbiology laboratories for its selective inhibition of Staphylococcus aureus and other coagulase-positive staphylococci, making it a valuable tool for bacterial identification and antimicrobial susceptibility testing.
-
Nitrocefin CAS:41906-86-9
Nitrocefin is a chromogenic cephalosporin substrate used in microbiology for the detection of beta-lactamase activity in bacteria. It serves as a diagnostic tool to identify bacteria that produce beta-lactamase enzymes capable of hydrolyzing beta-lactam antibiotics, such as penicillins and cephalosporins. Nitrocefin undergoes a color change from yellow to red in the presence of beta-lactamase, allowing for rapid visual detection of enzyme activity. This property makes nitrocefin a valuable tool in clinical laboratories for screening bacterial isolates and guiding antibiotic therapy decisions.
