Description

dalfopristin: component of RP-59500; structure in first source [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

dalfopristin : 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.
