WANG Yanan,LI Xiaoming,LÜ Fengyi,et al.Discovery of prenylated indole alkaloid and natural xanthone from cold-seep sediment derived fungus Talaromyces funiculosus SD-523[J].Journal of Oceanology and Limnology,2023,41(03):1152-1158.
A new prenylated indole alkaloid 11
17-
epi
-mangrovamide A (
1
)
a new natural occurring product
1
7-dihydroxy-6-methyl-8-hydroxymethyl-xanthone (
2
)
two known alkaloids
mangrovamide A (
3
) and mangrovamide G (
4
)
and four known polyketide derivatives (
5
–
8
) were isolated and identified from the cold-seep sediment derived fungal strain
Talaromyces funiculosus
SD-523. Their structures were elucidated by combination of nuclear magnetic resonance (NMR)
high resolution electrospray ionization mass spectroscopy (HRESIMS)
quantum chemical electronic circular dichroism (ECD)
and DP4+ probability analysis as well as by comparison of the data with literature reports. All isolated compounds were tested for antibacteria
l activities.
