  Alteration of the Bis-tetrahydrofuran Core Stereochemistries in Asimicin Can Affect the Cytotoxicity

  摘要：

  A systematic analysis using 10 synthetic asimicin stereoisomers revealed that the stereochemistry of the bis-tetrahydrofuran core, including the tetrahydrofuran rings and the adjacent hydroxy functions, had significant effect on its cytotoxicity. Our findings set to rest the highly controversial perception that the stereochemistry of the tetrahydrofuran core has little effect on the activity, which is not true for its cytotoxic effect, and also reinforces the previous conclusion that asimicin is a highly potent anticancer compound.

  Total synthesis of 27-hydroxy-bullatacin and its C-15 epimer, and studies on their inhibitory effect on bovine heart mitochondrial complex I functions

  摘要：

  The total synthesis of 27-hydroxybullatacin and its C-15 epimer has been achieved using rhenium(VII) oxides-mediated and Co(modp)(2)-catalyzed oxidative cyclization (OC), diastereoselective alkynylation, Brown's enantioselective allylboration, and Grubbs' cross metathesis as the key reactions. The inhibitory effect of these compounds on the complex I function, as determined by using bovine submitochondrial particles, was in low nanomolar range. (C) 2007 Elsevier Ltd. All rights reserved.

  The total synthesis and structure confirmation of the potent cytotoxic agent (−)-asimitrin (1), a C37 annonaceous acetogenin having a hydroxylated adjacent bis-tetrahydrofuran (THF) core, are described. The present synthesis features a highly stereoselective, chelate-controlled intramolecular amide enolate alkylation (IAEA) for the synthesis of key intermediate 17-hydroxy-16,17-erythro-16,19-trans-THF
