RESUMEN
Two new azaphilones, penimultiones A and B, together with seven known analogs were isolated from the culture of Penicillium multicolor LZUC-S2. Their structures were elucidated by detailed spectroscopic data analysis and chemical transformation. Penimultiones A and B belong to a rare class of azaphilones possessing a 1,3-dioxolane moiety. In addition, all compounds were evaluated for their antibacterial activity against five clinically bacterial strains inâ vitro, and three compounds showed potent antibacterial activity with minimum inhibitory concentration (MIC) values ranging from 12.5 to 50.0â µg/mL.
