Cat. No.: HY-B0479 Purity: 99.38%
Handling Instructions

Thiamphenicol (Thiophenicol), a methyl-sulfonyl derivative of Chloramphenicol, is a broad-spectrum antimicrobial antibiotic. Thiamphenicol acts by binding to the 50S ribosomal subunit, leading to inhibition of protein synthesis and bacteriostatic effect (against Gram-negative, Gram-positive aerobic and anaerobic bacteria).

Description

Thiamphenicol (Thiophenicol), a methyl-sulfonyl derivative of Chloramphenicol, is a broad-spectrum antimicrobial antibiotic. Thiamphenicol acts by binding to the 50S ribosomal subunit, leading to inhibition of protein synthesis and bacteriostatic effect (against Gram-negative, Gram-positive aerobic and anaerobic bacteria)[1][2].

In Vitro

Thiamphenicol shows a significant post-antibiotic effect (PAE) (0.33 to 2.9h) on all pathogens studied (S. pneumoniae, S. aureus and Escherichia coli) and a powerful bactericidal effect against β-lactamase-positive and -negative H. influenzae. Thiamphenicol MICs for the microorganisms analyzed are: 32 mg/L (S. aureus and E. coli), 2 mg/L (S. pneumoniae) and 0.25 mg/L (H. influenzae). Thiamphenicol shows a good in vitro activity against difficult-to-treat multiply resistant pathogens[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

The pharmacokinetics of Thiamphenicol (30 mg/kg) after single intravenous (IV) and oral (PO) administration is investigated in Mulard ducks. After IV administration, for Thiamphenicol, the mean residence time is 2.83 hours, the general half-life is 1.96 hours, the clearance is 0.04 L/hr/kg. Pharmacokinetics after PO administration is very similar for IV administration. Thiamphenicol shows rapid absorption and bioavailability of more than 70%[2].
