A New Prenylated Flavanone from Derris trifoliata Lour
TLDR
8-O-Methylelliptonol was isolated for the first time from the genus Derris and showed weak toxicity, while seven of the isolated compounds were found to be significantly toxic to brine shrimp.
Marcanine G, a new cytotoxic 1-azaanthraquinone from the stem bark of Goniothalamus marcanii Craib
TLDR
The ethanolic extract from the stem bark of Goniothalamus marcanii Craib was shown in preliminary brine shrimp lethality data having good cytotoxic activity and the assessment of cytotoxicity was established on an SRB assay using doxorubicin as a positive control.
Total synthesis of a cytotoxic acetogenin, pyranicin.
TLDR
The first total synthesis of a new cytotoxic acetogenin, pyranicin, is described, which was efficiently transformed into the 19,20-cis-THP derivative 18 through Mitsunobu lactonization.
Recent progress on the total synthesis of acetogenins from Annonaceae
TLDR
This review emphasizes only the first total synthesis of molecules of contemporary interest and syntheses that have helped to correct structures of annonaceous acetogenins.
Total synthesis of the proposed structure for pyragonicin.
TLDR
The total synthesis of acetogenin 1 reported for pyragonicin and its 10-epimer 32 is described and had spectroscopic data consistent with that of natural pyragonsicin, but a different optical rotation.

TLDR
The crude methanol extract of G. scortechinii showed a good and broad spectrum of antibacterial activity against both Gram-negative and Gram-positive bacteria and the growth inhibition of several nosocomial bacteria by Goniothalamus.

Gonionenin: A New Cytotoxic Annonaceous Acetogenin from Goniothalamus giganteus and the Conversion of Mono-THF Acetogenins to Bis-THF Acetogenins
TLDR
The resulting bis-THF compounds showed enhanced bioactivities, with (11) and (14) being over a billion times more cytotoxic than adriamycin against certain solid tumor cell lines.
Annonaceous Acetogenins from the Seeds of Annona squamosa. Non-adjacent Bis-tetrahydrofuranic Acetogenins.
Four non-adjacent bis-tetrahydrofuranic acetogenins, named squamostatins-B (2), -C (3), -D (4) and -E (5), have been isolated from the petroleum ether extract of Annona squamosa seeds. The structures
Determination of Absolute Configuration of Stereogenic Carbinol Centers in Annonaceous Acetogenins by 1H- and 19F-NMR Analysis of Mosher Ester Derivatives
The absolute configuration of the stereogenic carbinol centers in nine annonaceous acetogenins has been determined by careful 1 H- and 19 F-NMR analysis of (S)- and (R)-Mosher ester
Giganenin, a highly potent monotetrahydrofuran acetogenin and 4-deoxygigantecin from Goniothalamus giganteus
TLDR
Giganenin, the most cytotoxic of the monotetrahydrofuran acetogenins reported thus far, has been isolated from the bark of Goniothalamus giganteus by the use of brine shrimp lethality for bioactivity-directed fractionation.
Annonaceous acetogenins: a review.
The Annonaceous acetogenins are a series of apparently polyketide-derived fatty acid derivatives that possess tetrahydrofuran rings and a methylated gamma-lactone (sometimes rearranged to a methyl
Corossolone et corossoline, deux nouvelles γ-lactones mono-tétrahydrofuraniques cytotoxiques
The fractionation by solvents of the contents of the seeds of Annona muricata (Annonaceae), guided by the toxic activity towards the brine shrimp larva and the KB cancer cells, has enabled us to
