Microbial and reducing agents catalyze the rearrangement of taxanes
Sun, Di-An,Nikolakakis, Anastasia,Sauriol, Francoise,Mamer, Orval,Zamir, Lolita O.
, p. 1985 - 1992 (2001)
5α, 7β, 9α, 10β, 13α-Pentahydroxy-4(20),11(12)-taxadiene derivative 1 was converted to two unprecedented 1(15→11)abeo-taxanes and a taxane derivative with a C10-C11 double bond by Absidia coerula ATCC 10738a. A similar compound was obtained from treatment with zinc of a triacetoxy-4(20),11(12)-taxadiene derivative.
An unprecedented biogenetic-type chemical synthesis of 1(15→11) abeotaxanes from normal taxanes

supporting information; experimental part, p. 747 - 750 (2010/08/06)
A one-pot chemical process using BF3.Et2O for the synthesis of a new class of 1(15→11) abeotaxanes from normal taxanes has been developed. The chemical structures of rearranged 1(15→11) abeotaxane were established by extensive 2D NMR
In vitro and in vivo anticancer activity of 2-deacetoxytaxinine J and synthesis of novel taxoids and their in vitro anticancer activity
Reddy, K. Papi,Bid, Hemant K.,Nayak, V. Lakshma,Chaudhary, Preeti,Chaturvedi,Arya,Konwar, Rituraj,Narender
experimental part, p. 3947 - 3953 (2009/12/04)
The taxane diterpneoid 2-deacetoxytaxinine J (2-DAT-J) 1 has been isolated from the bark of Himalayan yew, Taxus baccata L. spp. wallichiana in a reasonably good yield (0.1%) and its anticancer activity against breast cancer cell lines (MCF-7 and MDA-MB-2
Synthesis and biological evaluation of new taxoids derived from 2-deacetoxytaxinine J
Botta, Maurizio,Armaroli, Silvia,Castagnolo, Daniele,Fontana, Gabriele,Pera, Paula,Bombardelli, Ezio
, p. 1579 - 1583 (2007/10/03)
A small library of 2-deacetoxytaxinine J (DAT-J) 1 derivatives was synthesised and tested in vitro for their reversal activity in human mammary carcinoma MDR cell line MCF7-R. One of the new taxoids showed to be active at 0.1 μM when tested in combination
Synthesis of paclitaxel (docetaxel) / 2-deacetoxytaxinine J dimers
Appendino, Giovanni,Belloro, Emanuela,Jakupovic, Sven,Danieli, Bruno,Jakupovic, Jasmin,Bombardelli, Ezio
, p. 6567 - 6576 (2007/10/03)
Starting from taxanes available in multigram amounts from widespread ornamental yews (10-deacetylbaccatin III (4) and 2'-deacetoxyaustrospicatine (5)), two dimeric taxoids (3a, 3b) with potential dual target specificity (β-tubulin and P-gp) were synthesised. Both compounds lacked significant cytotoxicity, though 3b retained a strong activity in the tubulin depolimerisation assay.
Synthesis of azetidine-type taxanes
Fenoglio,Nano,Vander Velde,Appendino
, p. 3203 - 3206 (2007/10/03)
Starting from the alkaloid 2'-deacetoxyaustrospicatine (2) azetidine isosteres of the oxetane-type laxane 1-deoxy-2-debenzoyloxy-4-deacetylbaccatin VI were synthesized.
