Pirlimycin
(Synonyms: 吡利霉素,U-57930E) 目录号 : GC12836An antibiotic of the lincosamide class
Cas No.:79548-73-5
Sample solution is provided at 25 µL, 10mM.
Pirlimycin, a lincosamide antibiotic, is effective against gram-positive bacteria, including Staphylococcus, Bacteroides, Streptococcus, and Plasmodium. It functions via inhibiting protein synthesis in bacteria by inducing premature dissociation of the peptidyl-tRNA from the ribosome.
In vitro: Pirlimycin showed activity against Helicobacter pylori with a minimal inhibitory concentration [MIC] 50 of 4 μg/ml and an MIC90 of 64 μg/ml [1].
In vivo: Cows were treated with 50 mg of pirlimycin via two intramammary infusions per quarter at a 24-hour interval (2-day) for 2, 5, or 8 days. Pirlimycin showed antibiotic therapy against environmental Streptococcus spp and Staphylococcus aureus intramammary individual and combined infections [1]. Specifically, pirlimycin cured environmental Streptococcus spp infections in 66.7% (14/21), 85% (17/20), 100% (14/14) in the 2-day group, 5-day group and 8-day group, respectively. S. aureus infections were cured by the treatment of pirlimycin in 13.3% (2/15), 31.3% (5/16), 83.3% (5/6) in the 2-day group, 5-day group and 8-day group, respectively. Furthermore, S. aureus, S. dysgalactiae subsp dysgalactiae, and Enterococcus spp intramammary infections were eliminated by the extended treatment of pirlimycin in 8-day group [2].
