Interactions of alpha- and beta-avoparcin with bacterial cell-wall receptor-mimicking peptides studied by electrospray ionization mass spectrometry.
van de Kerk-van Hoof A, Heck AJ. van de Kerk-van Hoof A, et al. J Antimicrob Chemother. 1999 Nov;44(5):593-9. doi: 10.1093/jac/44.5.593. J Antimicrob Chemother. 1999. PMID: 10552974
However, beta-avoparcin displayed slightly higher binding affinities than alpha-avoparcin, particularly for strong binding receptor-mimicking peptides. The evidence that alpha- and beta-avoparcin and vancomycin are structurally similar, combined with t …

Effect of avoparcin on rumen fermentation and duodenal nutrient flow in sheep.
Fébel H, Romváry A, Zsolnai-Harczi I, Huszár S. Fébel H, et al. Acta Vet Hung. 1995;43(2-3):229-46. Acta Vet Hung. 1995. PMID: 7491862
The feeding of control diets was followed by the administration of experimental diets containing avoparcin (groups I+A, II+A, and III+A). The dose of avoparcin was 0.75 mg/kg body weight. ...When added to a ration of high NSC and RDP content (I), avoparcin de …

Nuclear magnetic resonance studies on the interaction of avoparcin with model receptors of bacterial cell walls.
Fesik SW, Armitage IM, Ellestad GA, McGahren WJ. Fesik SW, et al. Mol Pharmacol. 1984 Mar;25(2):281-6. Mol Pharmacol. 1984. PMID: 6700574
For the beta-avoparcin: Ac2-L-Lys-D-Ala-Ala complex, the COOH-terminal end of the tripeptide is located near the NH2 terminus of the antibiotic with the tripeptide extending across the peptide backbone of beta-avoparcin toward its COOH-terminal end. ...The associati …

The use of avoparcin as a growth promoter and the occurrence of vancomycin-resistant Enterococcus species in Norwegian poultry and swine production.
Kruse H, Johansen BK, Rørvik LM, Schaller G. Kruse H, et al. Microb Drug Resist. 1999 Summer;5(2):135-9. doi: 10.1089/mdr.1999.5.135. Microb Drug Resist. 1999. PMID: 10432274
In a survey conducted in Norway between June, 1995 and March, 1997, VRE were isolated from fecal samples from 106 out of 109 poultry houses previously exposed to avoparcin (97%) and from six out of 33 poultry houses never exposed to avoparcin (18%) (RR = 5.35). ...T …

Avoparcin, a glycopeptide used in animal foods: antimicrobial spectrum and potency tested against human isolates from the United States.
Cormican MG, Erwin ME, Jones RN. Cormican MG, et al. Diagn Microbiol Infect Dis. 1997 Dec;29(4):241-8. doi: 10.1016/s0732-8893(97)00134-x. Diagn Microbiol Infect Dis. 1997. PMID: 9458981
Avoparcin is a glycopeptide antimicrobial that is widely used as a growth promoter in animal feeds in portions of Western Europe. ...There was a good correlation of avoparcin MICs with the MICs for vancomycin and teichoplanin for most species; however, the avopar …

Determination of avoparcin in animal formulations by capillary electrophoresis.
Lucas C, Gliddon MJ, Safarpour MM, Cardaciotto S, Ahuja ES, Foley JP. Lucas C, et al. J Capill Electrophor Microchip Technol. 1999 May-Aug;6(3-4):75-83. J Capill Electrophor Microchip Technol. 1999. PMID: 11315156
Titration data fitted to two sigmoidal functions reveal pKas of 7.99 for beta-avoparcin and 10.3 for alpha-avoparcin. The differing pH dependence of the effective electrophoretic mobilities of alpha- and beta-avoparcin resulted in an optimum pH of 9.2 …

Epimerization and stereochemistry of avoparcin.
Ellestad GA, Swenson W, McGahren WJ. Ellestad GA, et al. J Antibiot (Tokyo). 1983 Dec;36(12):1683-90. doi: 10.7164/antibiotics.36.1683. J Antibiot (Tokyo). 1983. PMID: 6662809 Free article.
The epimerization of avoparcin entities is discussed in some detail. The absolute stereochemistry of avoparcin is now known since the N-methyl terminal amino acid of the aglycone has been isolated and shown to exhibit negative optical rotation and hence has the R-co …
