• Methylsulfonyl chloramphenicol

2,2-디클로로-N-[2-하이드록시-1-(하이드록시메틸)-2-[4-(메틸술포닐)페닐]에틸]아세트아미드 화학적 특성, 용도, 생산

• 화학적 성질

  Off-White Solid

• 용도

  Thiamphenicol is an antibiotic. Thiamphenicol is the methyl-sulfonyl analogue of chloramphenicol and has a similar spectrum of activity, but is 2.5 to 5 times as potent. Thiamphenicol is used particul arly for the treatment of sexually transmitted infections and pelvic inflammatory disease.

• Antimicrobial activity

  It is generally less active than chloramphenicol, but is equally active against Str. pyogenes, Str. pneumoniae, H. influenzae and N. meningitidis, including some strains resistant to chloramphenicol. It is more actively bactericidal against Haemophilus and Neisseria spp.

• 원료

  There is complete cross-resistance with chloramphenicol in those bacteria which elaborate acetyltransferase, although the affinity of the enzyme for thiamphenicol is lower. Organisms that owe their resistance to other mechanisms may be susceptible.

• Pharmacokinetics

  An oral dose of 500 mg produces a peak plasma level of 3–6 mg/L after about 2 h. The plasma half-life is 2.6–3.5 h. It is said to reach the bronchial lumen in concentrations sufficient to exert a bactericidal effect on H. influenzae. Unlike chloramphenicol it is not a substrate for hepatic glucuronyl transferase; it is not eliminated by conjugation, and its half-life is not affected by phenobarbital induction.
  About 50% of the dose can be recovered in an active form in the urine within 8 h and 70% over 24 h. The drug is correspondingly retained in the presence of renal failure, and in anuric patients the plasma half-life has been reported to be 9 h, a value not significantly affected by peritoneal dialysis. Biliary excretion is believed to account for removal of the antibiotic in anuric patients. The plasma concentration is elevated and half-life prolonged in patients with hepatitis or cirrhosis.

• Clinical Use

  Similar to that of chloramphenicol.

• 부작용

  There are no reports of irreversible bone-marrow toxicity. This has been related to the absence of the nitro group, and hence its reduction products, and differences in the biochemical effects of thiamphenicol and chloramphenicol on mammalian cells. It exerts a greater dose-dependent reversible depression of hemopoiesis and immunogenesis than chloramphenicol, and has been used for its immunosuppressive effect. Therapeutic doses (1–1.5 g) are likely to depress erythropoiesis in the elderly or others with impaired renal function.

• Purification Methods

  Recrystallise thiamphenicol from H2O or CHCl3. The UV has max at 224, 266 and 274nm ( 13,700, 800 and 700) in 95% EtOH. The 1S,2S-isomer [1478651-7] has m 164.3-166.3o (from H2O/EtOAc/pet ether) and [] D 25 -12.6o (c 1, EtOH); and the racemate 1RS,2RS-Racefenical [847-25-6] has m 181-183o (dec) from CHCl3/EtOAc/pet ether.
