  Cytotoxic Responses to Aromatic Ring and Configurational Variations in α-Conidendrin, Podophyllotoxin, and Sikkimotoxin Derivatives

  摘要：

  Derivatives of alpha -conidendrin, podophyllotoxin, and sikkimotoxin were prepared to evaluate the cytotoxic contributions of C-4 configuration and pendant and fused arene substitutions. Dimethyl-alpha -conidendryl alcohol (5), 9-deoxypodophyllol (6), and 9-deoxysikkimol (17) were dehydrated to their respective oxolane derivatives 4, 3, and 9. Diols 5 and 6 were converted via oxabicyclo[3.2.1] octanols 10 and 14 to target oxolanes 8 and 7 where C-4 had been inverted relative to that in 3 and 4. Cytotoxicities of the five oxolanes were determined in two drug-sensitive human leukemia and two multidrug-resistant cell lines expressing P-glycoprotein or multidrug-resistance associated protein (MRP). Changing the pendant arene configuration or replacing a m-methoxy by hydrogen resulted in a 100-fold cytotoxicity loss. Replacing a methylenedioxy group in the fused arene by two methoxy substituents reduced cytotoxicity by 10-fold. Drug-resistant cell lines were equally resistant to compounds 3, 4, 8, and 9 indicating that these four compounds do not serve as substrates of the transport proteins P-glycoprotein and MRP.

• Modes of Methyleneoxy Bridging and Their Effect on Tetrahydronaphthalene Lignan Cytotoxicity

  Dioxatricyclodecane, oxabicyclooctane, and benzodihydropyran derivatives of alpha-conidendrin (ACON), podophyllotoxin (PT), and sikkimotoxin (SK) were prepared to learn which methyleneoxy bridging modes and arene and aryl substituents coincided with high cytotoxicity. PT-derived dioxatricyclodecane 14 showed in vitro activity at 10(-8) M. SK analogue 12 was less active, and ACON analogue 11 was inactive at 10(-4) M. In vivo intraperitoneal and subcutaneous activities of 14 were observed. In vitro cytotoxicities were higher for oxabicyclooctanes when hydroxymethyl group and methyleneoxy bridge were cis, as in deoxypicropodophyllin analog 20, rather than trans, as in PT analogue 5. Acetylation of the hydroxymethyl group of 20 lowered activities, whereas acetylation of 5 increased or lowered activities. Reduction of the hydroxymethyl group of 5 to a methyl group increased cytotoxicities. Molecular dynamics indicated the THN scaffold of benzodihydropyrans was conformationally mobile, but scaffolds of oxabicyclooctanes and dioxatricyclodecanes were immobile. Each of three PT-benzodihydropyrans was less active than its oxabicyclooctane counterpart.

  (−)-deoxysikkimotoxin (7) have been carried out, in an attempt to exploit a synthetic strategy recently developed for the synthesis of (−)-deoxypodophyllotoxin (1, R1 = -CH2−, Ar = 3,4,5-trimethoxyphenyl). In so doing, a generalized method for the synthesis of aryltetralin lignans has been developed that should be applicable to a variety of substitution patterns and stereochemistries. A one-pot, 100%
