| 产品描述 | Dalfopristin (mesylate) is a streptogramin antibiotic and a 50S ribosome inhibitor [1][2]. Streptogramins are produced by a variety of Streptomyces sp as a mixture (ratio of 7:3) of two chemically unrelated compounds, type A and B. Dalfopristin, the type A Streptogramin, is often combined with type B streptogramin antibiotic, quinupristin, to produce Quinupristin-Dalfopristin Complex, known commercially as Synercid. Synercid is used to treat skin infections, and is also active against some Gram-negative and anaerobic bacteria [2][3]. The ribosome is composed of two ribonucleoprotein subunits, the 50S and 30S. The 50S ribosome inhibitors inhibited protein synthesis [2]. Dalfopristin is a cyclic polyunsaturated macrolactone that interferes with binding of tRNA substrates to both A- and P-sites [2]. Dalfopristin blocked the access of peptidyl-tRNAs to the ribosome and peptidyltransferase elongation reaction in bacteria [1]. quinupristin and dalfopristin acted synergistically to kill Gram-positive bacteria, as well as some Gram-negative and anaerobic bacteria [2][3]. Dalfopristin hydrolyzed rapidly to virginiamycin M under physiological conditions. References: |
