Cephapirin

(6R,7R)-3-[(acetyloxy)methyl]-8-oxo-7-[2-(pyridin-4-ylsulfanyl)acetamido]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid

C17H17N3O6S2 (423.0559)


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

   

Glucoiberin

{[(E)-(4-methanesulfinyl-1-{[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]sulfanyl}butylidene)amino]oxy}sulfonic acid

C11H21NO10S3 (423.0328)


Glucoiberin belongs to the class of organic compounds known as alkylglucosinolates. These are organic compounds containing a glucosinolate moiety that carries an alkyl chain. Glucoiberin is an extremely weak basic (essentially neutral) compound (based on its pKa). Glucoiberin has been detected, but not quantified in, several different foods, such as capers, cauliflowers, cabbages, Brassicas, and Chinese cabbages. This could make glucoiberin a potential biomarker for the consumption of these foods. Glucoiberin is isolated from the seeds of Brassica oleracea and other crucifers. Isolated from seeds of Brassica oleracea and other crucifers. Glucoiberin is found in many foods, some of which are white cabbage, cabbage, broccoli, and brussel sprouts.
