세프메녹심 화학적 특성, 용도, 생산

• 용도

  Cefmenoxime (cas# 65085-01-0) is a compound useful in organic synthesis.

• 정의

  ChEBI: A third-generation cephalosporin antibiotic, bearing a 2-(2-amino-1,3-thiazol-4-yl)-2-(methoxyimino)acetyl]amino group at the 7beta-position and a [(1-methyl-1H-tetrazol-5-yl)sulfanyl]methyl group at the 3-position.

• Antimicrobial activity

  A semisynthetic cephalosporin supplied as the hydrochloride. Its activity is very similar to that of cefotaxime. A 500 mg intramuscular injection achieves a plasma concentration of 15 mg/L after 40 min. A concentration of 200 mg/L is attained after intravenous administration of 1 g. The plasma half-life is c. 1 h. Around 77% is protein bound. Probenecid increases peak plasma levels and extends the plasma half-life to 1.8 h. Therapeutic concentrations are achieved in CSF. There is a degradation product with a long half-life (around 40 h), but 80–92% of the drug is recovered unchanged from the urine. In patients with renal insufficiency, no significant relation was found between creatinine clearance and peak serum concentrations but there was a linear relationship with plasma half-life and total body clearance. About 10% of the dose appears in the feces, mostly extensively degraded, possibly by the fecal flora.
  Toxicity, side effects and clinical use are those common to group 4 cephalosporins.
