Fig 6c Fig. 6 MALDI-MSI of U13C-PC16:0/16:0 acyl chain remodeling. A: Averaged MALDI mass spectrum from lung tissue collected from mice euthanized 12 h after administration of D9-choline and U13C-DPPC–containing Poractant alfa surfactant. The ion at m/z 828.6321 is assigned as the [M+Na]+ ion of 13C24-PC16:0_20:4 formed by acyl remodeling of U13C-PC16:0/16:0. The “NL” value refers to the intensity of the base peak in the full range MS1 spectrum. B: MS/MS spectrum of precursor ions at m/z 828.5 ± 0.5 with fragment ions originating from [13C24-PC16:0_20:4+Na]+ annotated. Part-per-million (ppm) mass errors are provided in parentheses. C, D: MALDI-MSI data of [U13C-DPPC+Na]+ (blue), [PC36:4+Na]+ (green) and [13C24-PC16:0_20:4+Na]+ (red) in lung tissue collected from mice (C) 12 h and (D) 18 h after label administration. All images were visualized using total-ion-current normalization and hotspot removal (high quantile = 99%). MS/MS, tandem mass spectrometry; MSI, mass spectrometry imaging; PC, phosphatidylcholine; U13C-DPPC, universally 13C-labeled dipalmitoyl PC.

Description


Cephapirin is an injectable, first-generation cephalosporin antibiotic that has a wide spectrum of activity against gram-positive and gram-negative organisms. The bactericidal activity of cephapirin results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). Cephapirin is more resistant to beta-lactamases than the penicillins, and therefore is effective against staphylococci, with the exception of methicillin-resistant staphylococci. Cephapirin is FDA approved for use in food-producing animals, especially dairy cattle. Cephapirin is used for the treatment of mastitis in cows. Production for use in humans has been discontinued in the United States. It is marketed under the trade name Cefadyl. Active against gram-positive and -negative bacteria (vet. use). FDA approved for use in food producing animals, especies dairy cattle. It is used for the treatment of mastitis in cows J - Antiinfectives for systemic use > J01 - Antibacterials for systemic use > J01D - Other beta-lactam antibacterials > J01DB - First-generation cephalosporins D000890 - Anti-Infective Agents > D000900 - Anti-Bacterial Agents > D002511 - Cephalosporins D000890 - Anti-Infective Agents > D000900 - Anti-Bacterial Agents > D047090 - beta-Lactams D000890 - Anti-Infective Agents > D000900 - Anti-Bacterial Agents > D007769 - Lactams C254 - Anti-Infective Agent > C258 - Antibiotic > C260 - Beta-Lactam Antibiotic
