Lipoxazolidinones A, B, and C: Antibacterial 4-Oxazolidinones from a Marine Actinomycete Isolated from a Guam Marine Sediment
摘要:
Marine actinomycete strain NPS008920, a member of the new genus Marinispora, was isolated from a sediment sample collected in Cocos Lagoon, Guam. In natural sea water containing media, the strain produced a series of novel 2-alkylidene-5-alkyl-4-oxazolidinones, lipoxazolidinone A (1), B (2), and C (3). Compounds 1-3 showed broad spectrum antimicrobial activity similar to that of the commercial antibiotic linezolid (Zyvox), a 2-oxazolidinone. Hydrolysis of the amide bond of the 4-oxazolidinone ring of 1 resulted in loss of antibacterial activity. The 2-alkylidene-4-oxazolidinone represents a new antibiotic pharmacophore and is unprecedented in nature.
Disclosed herein are various novel oxazolidinone, imidazolidinone, and thiazolidinone analogs and methods of treating cancer and/or microbial infection using these analogs. Particular 4-oxazolidinone compounds are shown to have anti-cancer and anti-microbial activity.
