polyketides from Streptomyces lucensis. Complete workup of the fermentation extract of this strain allowed for the isolation of seven new compounds, lucensimycins A−G (1−3, 4a, 5−7), with varying degrees of antibacterial activities. Lucensimycin E (5) exhibited the best activity and showed MIC values of 32 μg/mL against Staphylococcus aureus and 8 μg/mL against Streptococcus pneumoniae. The isolation, structure
