Abstract

BACKGROUND:
Paclitaxel (taxol) is a potent anticancer drug that is used in the treatment of a wide variety of cancerous. In the present study, we identified a taxol derivative named 7-epi-10-deacetyltaxol (EDT) from the culture of an endophytic fungus Pestalotiopsis microspora isolated from the bark of Taxodium mucronatum. This study was carried out to investigate the effects of fungal EDT on cell proliferation, the induction of apoptosis and the molecular mechanisms of apoptosis in human hepatoma HepG2 cells in vitro.

METHODS:
The endophytic fungus was identified by traditional and molecular taxonomical characterization and the fungal EDT was purified using column chromatography and confirmed by various spectroscopic and chromatographic comparisons with authentic paclitaxel. We studied the in vitro effects of EDT on HepG2 cells for parameters such as cell cycle distribution, DNA fragmentation, reactive oxygen species (ROS) generation and nuclear morphology. Further, western blot analysis was used to evaluate Bcl-2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), p38-mitogen activated protein kinase (MAPK) and poly [ADP-ribose] polymerase (PARP) expression.

RESULTS:
We demonstrate that the fungal EDT exhibited significant in vitro cytotoxicity in HepG2 cells. We investigated cytotoxicity mechanism of EDT in HepG2 cells. The results showed nuclear condensation and DNA fragmentation were observed in cells treated with fungal EDT. Besides, the fungal EDT arrested HepG2 cells at G2/M phase of cell cycle. Furthermore, fungal EDT induced apoptosis in HepG2 cells in a dose-dependent manner associated with ROS generation and increased Bax/Bcl-2 ratio, p38 MAPKs and PARP cleavage.

CONCLUSIONS:
Our data show that EDT induced apoptotic cell death in HepG2 cells occurs through intrinsic pathway by generation of ROS mediated and activation of MAPK pathway. This is the first report for 7-epi-10-deacetyltaxol (EDT) isolated from a microbial source.

Abstract

From a CH2Cl2 extract of the bark of Taxus wallichiana, six new taxoids, wallitaxanes A-F (1-6), were isolated, together with 29 known compounds. The structures of the new compounds were elucidated on the basis of spectroscopic data interpretation. Wallitaxane D (4) was identified as an opened oxetane-type taxoid having the first naturally occurring C(H)-20 acetal group, while wallitaxanes E (5) and F (6) are representative of the rare abeo-taxoid class. The isolated compounds were evaluated for their α-glucosidase inhibitory activity and for cytotoxicity against the HeLa human cervical cancer cell line. In the present work, taxanes were found to exhibit α-glucosidase inhibitory activity for the first time, and wallitaxane A (1) showed the most potent effect, with an IC50 value of 3.6 μM. In turn, 7-epi-taxol (16) and 7-epi-10-deacetyltaxol (17) showed IC50 values of 0.05 and 0.085 nM, respectively, against HeLa cells.

Abstract

The response of two Taxus cell systems to the action of cyclodextrin (CD) and coronatine (CORO), supplied to the culture medium either separately or together, was studied. Two-stage Taxus globosa and Taxus media cell cultures were established and the elicitors were added at the beginning of the second stage. Growth, taxane production, and the expression of known taxol biosynthetic genes, including the recently characterized CoA ligase gene, were studied. Although CORO reduced the growth capacity of both cell lines, CD apparently counteracted this negative effect. Taxane production was significantly enhanced by the simultaneous addition of CD and CORO to the medium. The total taxane production in the T. media cell line was more than double that of T. globosa, but in the latter more than 90% of the taxanes produced were excreted to the medium. Individual taxane patterns also differed: at the height of production, the main taxanes in T. globosa cultures were cephalomannine and 10-deacetyltaxol, and in T. media, taxol and baccatin III. The low transcript levels of taxane biosynthetic genes found in T. globosa cells mirrored the lower taxane production in these cultures, while a high expression was strongly correlated with a high taxane production in T. media.

Description :

10-Deacetyltaxol (10-Deacetylpaclitaxel) is a taxane derivative isolated from Taxus wallichiana Zucc[1]. 10-Deacetyltaxol (10-Deacetylpaclitaxel) promotes the polymerization of tubulin and to inhibit the depolymerization of microtubules induced by cold or by calcium ions in vitro[2]. 10-Deacetyltaxol (10-Deacetylpaclitaxel) exhibits cytotoxicity in human glial and neuroblastoma cell-lines[3].
