  The Synthesis and Biological Activity of 9- and 2′-cAMP 7-Deoxypaclitaxel Analogues from 5-Cinnamoyltriacetyltaxicin-I

  摘要：

  The synthesis and biological activity of new 7-deoxypaclitaxel analogues 3 and 4 in which the hydroxy group at C-2' of the sidechain, C-9 and C-10 in the B-ring are substituted by cAMP and benozoyloxy group respectively are presented. These derivatives have been first synthesized from a natural taxoid 5-cinnamoyltriacetyltaxicin-1 5 and tested in vitro for cytotoxicity against three human tumor cell lines. The biologically tested results indicate 3 having more potent cytotoxicity and 4 having a remarkably reduced cytotoxicity as well as 33 having no much effect on cytotoxicity against all human tumor cell lines tested in comparison to that of paclitaxel.

  Total Synthesis of 1‐Hydroxytaxinine

  摘要：

  Abstract1‐Hydroxytaxinine (1) is a cytotoxic taxane diterpenoid. Its central eight‐membered B‐ring possesses four oxygen‐functionalized centers (C1, C2, C9, and C10) and two quaternary carbon centers (C8 and C15), and is fused with six‐membered A‐ and C‐rings. The densely functionalized and intricately fused structure of 1 makes it a highly challenging synthetic target. Reported here is an efficient radical‐based strategy for assembling 1 from A‐ and C‐ring fragments. The A‐ring bearing an α‐alkoxyacyl telluride moiety underwent intermolecular coupling with the C‐ring fragment by a Et3B/O2‐promoted decarbonylative radical formation. After construction of the C8‐quaternary stereocenter, a pinacol coupling reaction using a low‐valent titanium reagent formed the B‐ring with stereoselective installation of the C1,C2‐diol. Subsequent manipulations at the A‐ and C‐rings furnished 1 in 26 total steps.

  Abstract A collection of yew needles afforded a taxane diester characterized by an additional bond between C-3 and C-11. The structure was elucidated by spectral methods, and further confirmed by synthesis from a known taxane derivative. A general procedure for the photocyclization of taxicins is reported.

  Novel 9-functional heterocyclic coupled 7-deoxy-9-dihydropaclitaxel analogues 17 and 22-24 synthesized from a natural taxoid 5-cinnamoyltriacetyltaxicin-I (3) and their biological evaluation in tubulin assembly activity and cytotoxicity in vitro against several human tumor cell lines are first presented. The biologically tested results show that 17, 22 and 23 are inactive in tubulin assembly assay and have no more remarkable cytotoxicities against human tumor cell lines SK-0V3, WIDR and MCF-7, though 22 and 23 exhibit more potent cytotoxicity against human liver cancer and human esophagus cancer cell lines (BEL-7402 and ECa-109) than paclitaxel.

  Taxane group of diterpenoids 2 and 3 which possess cinnamoyl moiety at C-5 position underwent selective cleavage to C-5 hydroxy compounds 4 and 5 on treatment with hydroxylamine. The resulting compounds were characterised based on their spectral data.
