Cefixime, sold under the brand name Suprax among others, is an antibiotic medication used to treat a number of bacterial infections. [5] These infections include otitis media , strep throat , pneumonia , urinary tract infections , gonorrhea , and Lyme disease . [ 5 ]
Cefoperazone contains an N-methylthiotetrazole (NMTT or 1-MTT) side chain.As the antibiotic is broken down in the body, it releases free NMTT, which can cause hypoprothrombinemia (likely due to inhibition of the enzyme vitamin K epoxide reductase) and a reaction with ethanol similar to that produced by disulfiram (Antabuse effect), due to inhibition of aldehyde dehydrogenase.
Cefuroxime is then released for systematic circulation. If cefuroxime axetil is given with food, absorption values can increase from 37% in fasting patients to 52% in fed patients. [5] Distribution: It has been reported that after cefuroxime axetil administration, it can be found in tonsil tissue, sinus tissue, bronchial tissue and middle ear ...

Unlike other second-generation cephalosporins, cefuroxime can cross the blood–brain barrier. [ 12 ] A systematic review found high quality evidence that injecting the eye with cefuroxime after cataract surgery will lower the chance of developing endophthalmitis after surgery.
Cefepime is a fourth-generation cephalosporin antibiotic.Cefepime has an extended spectrum of activity against Gram-positive and Gram-negative bacteria, with greater activity against both types of organism than third-generation agents.
Cefotaxime is an antibiotic used to treat several bacterial infections in humans, other animals, and plant tissue culture. [3] Specifically in humans it is used to treat joint infections, pelvic inflammatory disease, meningitis, pneumonia, urinary tract infections, sepsis, gonorrhea, and cellulitis. [3]
The epoxide is opened at the least hindered end with 1-methyl-1H-tetrazole-5-thiol to put in place the future C-3 side chain and give intermediate 5. Jones oxidation followed in turn by ozonolysis (reductive work-up with zinc-AcOH) and reaction with SOCl2 and pyridine give halide 6. The stage is now wet for intramolecular Wittig reaction.
