| Hazard Information | Back Directory | [Uses]
A Viiginiamycin M1 (V672810) derivative. A streptogramin antibiotic used to treat infections by staphylococci and by vancomycin-resistant Enterococcus faecium. | [Uses]
Dalfopristin is a semi-synthetic analogue of ostreogrycin A (virginiamycin M, pristinamycin IIA, streptogramin A) formed by addition of diethylaminoethylthiol to the 2-pyrroline group of ostreogrycin, followed by oxidation to the sulfone. The structural changes provide a more hydrophobic compound with a readily ionisable group for generating a salt. Dalfopristin is used commercially in synergistic combination with quinupristin (70:30). There is little published data on the synthesis, biological or antibiotic activity of dalfopristin alone, however the combination product is highly effective, including activity against antibiotic resistant strains. | [Uses]
Dalfopristin is a semi-synthetic analogue of ostreogyrcin A (virginiamycin M, pristinamycin IIA, streptogramin A) formed by addition of diethylaminoethylthiol to the 2-pyrroline group of ostreogyrcin, followed by oxidation to the sulphone. The structural changes provide a more hydrophobic compound with a readily ionisable group for generating a salt. Dalfopristin is used commercially in synergistic combination with quinupristin (70:30). There is little published data on the synthesis, biological or antibiotic activity of dalfopristin alone, however the combination product is highly effective, including activity against antibiotic resistant strains. | [Definition]
ChEBI: Dalfopristin is a macrolide that is pristinamycin IIA in which the double bond between positions 26 and 26a of the pyrroline ring has been reduced and position 26R carries a [2-(diethylamino)ethyl]sulfonyl group. It is a semi-synthetic streptogramin antibiotic and often used as a mixture with quinupristin for the treatment of vancomycin-resistant Enterococcus faecium. It has a role as an antibacterial drug and a protein synthesis inhibitor. It is a macrolide, a member of 1,3-oxazoles, a cyclic ketone, an enamide, a secondary alcohol, a secondary carboxamide, a tertiary carboxamide, a sulfone, a tertiary amino compound, a carboxylic ester and a macrolide antibiotic. It is functionally related to a pristinamycin IIA. | [in vivo]
Dalfopristin (12 mg/kg/day, i.v., 7 days) shows no effects on hepatic cytochrome P-450 metabolite complexes in rats[2].
