| Dalfopristin | 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 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. Synonyms: Dalfopristinum. Grades: >98% by HPLC. CAS No. 112362-50-2. Molecular formula: C34H50N4O9S. Mole weight: 690.85. |  |

| Quinupristin | Quinupristin is an antibiotic and usually used in combination with dalfopristin (The trade name is Synercid). It is active against Gram-positive bacteria through inhibiting protein synthesis of the cells, but not active against Gram-negative bacteria, so it needs to be given in combination with other antibacterials for mixed infections which also involve Gram-negative organisms. Uses: Semisynthetic depsipeptide type i streptogramin. an antibacterial agent. Synonyms: N-((6R, 9S, 10R, 13S, 15aS, 18R, 22S, 24aS)-22-(4-(dimethylamino)benzyl)-6-ethyl-10, 23-dimethyl-5, 8, 12, 15, 17, 21, 24-heptaoxo-13-phenyl-18-((((S)-quinuclidin-3-yl)thio)methyl)docosahydro-12H-pyrido[2, 1-f]pyrrolo[2, 1-l][1]oxa[4, 7, 10, 13, 16]pentaazacyclononadecin-9-yl)-3-hydroxypicolinamide; RP68888; RP57669; Antibiotic RP 57669; 4-[4-(Dimethylamino)-N-methyl-L-phenylalanine]-5-[(2S,5R)-5-[[[(3S)-1-azabicyclo[2.2.2]oct-3-yl]thio]methyl]-4-oxo-2-piperidine carboxylic acid] Virginiamycin S1.
