Cytotoxic alkaloids and antibiotic nordammarane triterpenoids from the marine-derived fungus Aspergillus sydowi.
TLDR
Three new diketopiperazine alkaloids, 6-methoxyspirotry Prostatin B, 18-oxotryprostatin A, and 14-hydroxyterezine D, as well as 12 known compounds, were isolated from the ethyl acetate extract of a marine-derived fungal strain, Aspergillus sydowi PFW1-13, by comprehensive spectroscopic analysis.
Aspergiolide A, a novel anthraquinone derivative with naphtho [1,2,3 -de]chromene -2,7 -dione skeleton isolated from a marine-derived fungus Aspergillus glaucus
Aspergiolide A (1), an anthraquinone derivative with naphtho[1,2,3-de]chromene-2,7-dione skeleton, has been isolated from cultures of a marine-derived fungus Aspergillus glaucus. The structure and
Isoechinulin-type alkaloids, variecolorins A-L, from halotolerant Aspergillus variecolor.
TLDR
Twelve new compounds, variecolorins A-L ( 1- 12), together with eleven known analogues ( 13- 23) were isolated from the broth of a halotolerant fungus, Aspergillus varie color, and exhibited weak radical scavenging activity against DPPH.
Isolation, Structure Elucidation, and Antimycobacterial Properties of Dimeric Naphtho‐γ‐pyrones from the Marine‐Derived Fungus Aspergillus carbonarius
TLDR
Two new dimeric naphtho‐γ‐pyrones, compounds 1 and 2, were isolated from the AcOEt extract of the fungal strain WZ‐4‐11 of Aspergillus carbonarius and showed weak antimycobacterial activities against Mycobacterium tuberculosis H37Rv.
Aurantiomides A-C, quinazoline alkaloids from the sponge-derived fungus Penicillium aurantiogriseum SP0-19.
Three new quinazoline alkaloids, aurantiomides A (1), B (2), and C (3), along with the known metabolite anacine (4) were isolated from the sponge-derived fungus strain Penicillium aurantiogriseum
Secalonic acid D; A cytotoxic constituent from marine lichen-derived fungusGliocladium sp. T31
TLDR
This is the first report on the isolation of SAD from this fungus, as well as its inhibitory effect on K562 cell cycle and its cytotoxicity against several tumor cell lines in vitro.
Seven new prenylated indole diketopiperazine alkaloids from holothurian- derived fungus Aspergillus fumigatus
Seven new prenylated indole diketopiperazine alkaloids, including compound 1, 3 spirotryprostatins C–E (2–4), 2 derivatives of fumitremorgin B (5 and 6), and 13-oxoverruculogen (7), have been
Phenylspirodrimanes with anti-HIV activity from the sponge-derived fungus Stachybotrys chartarum MXH-X73.
TLDR
Seven new phenylspirodrimanes, named stachybotrins D-F, stachybocins E and F, and stachybosides A and B, and four known compounds, were isolated from the sponge-derived fungus Stachybotrys chartarum MXH-X73, and compound 1 showed an inhibitory effect on HIV-1 replication by targeting reverse transcriptase.
Antiviral alkaloids produced by the mangrove-derived fungus Cladosporium sp. PJX-41.
TLDR
Six new indole alkaloids including five new glyantrypine derivatives and a new pyrazinoquinazoline derivative and four known alkaloid derivatives were isolated from the culture of the mangrove-derived fungus Cladosporium sp.
Three Novel, Structurally Unique Spirocyclic Alkaloids from the Halotolerant B‐17 Fungal Strain of Aspergillus variecolor
TLDR
Three novel alkaloids were isolated from the mycelia of the halotolerant fungal strain Aspergillus variecolor B‐17, found to share an unprecedented ‘spiro‐anthronopyranoid diketopiperazine’ structure, with a stable hemiaminal function, and were shown to exhibit weak cytotoxic and antioxidant activities.
