Biogenetic relationships between Annonaceous acetogenins: squamocin is not a precursor of chamuvarinin based on a semisynthetic study.
In the course of reactivity studies on squamocin (1), a highly cytotoxic acetogenin from the plant family Annonaceae, two diastereomers, 3 and 4, of chamuvarinin (2) were synthesized. Based on this, a plausible relative configuration was proposed for 2, demonstrating the absence of any biogenetic link between 1 and 2. The new analogues 3, 4, and 7 were also tested for their ability to induce apoptosis.

Chamuvarinin, an acetogenin bearing a tetrahydropyran ring from the roots of Uvaria chamae.
A new cytotoxic acetogenin, chamuvarinin (1), containing a tetrahydropyran ring with an adjacent bis-tetrahydrofuran ring, which corresponds to a novel carbon skeleton in this series, was isolated from the roots of Uvaria chamae, together with the previously reported acetogenins squamocin (2), desacetyluvaricin (3), and neoannonin (4). The structure determination of chamuvarinin (1) was based on extensive NMR studies and high-resolution mass spectral measurements. This new compound shows significant cytotoxicity toward the KB 3-1 cell line (IC50 = 8 x 10(-10) M). In addition, a biosynthetic relationship between 1 and 2 is briefly discussed.
