Description: Teniposide is a semisynthetic derivative of podophyllotoxin with antineoplastic activity. Teniposide forms a ternary complex with the enzyme topoisomerase II and DNA, resulting in dose-dependent single- and double-stranded breaks in DNA, DNA: protein cross-links, inhibition of DNA strand religation, and cytotoxicity. This agent acts in the late S or early G phase of the cell cycle.

More Info: CLINICAL PHARMACOLOGY Teniposide is a phase-specific cytotoxic drug, acting in the late S or early G2 phase of the cell cycle, thus preventing cells from entering mitosis. Teniposide causes dose-dependent single- and double-stranded breaks in DNA and DNA-protein cross-links. The mechanism of action appears to be related to the inhibition of type II topoisomerase activity since teniposide does not intercalate into DNA or bind strongly to DNA. The cytotoxic effects of teniposide are related to the relative number of double-stranded DNA breaks produced in cells, which are a reflection of the stabilization of a topoisomerase II-DNA intermediate. Teniposide has a broad spectrum of in vivo antitumor activity against murine tumors, including hematologic malignancies and various solid tumors. Notably, teniposide is active against sublines of certain murine leukemias with acquired resistance to cisplatin, doxorubicin, amsacrine, daunorubicin, mitoxantrone, or vincristine.    Other CAS# CAS#23362-13-2; CAS#31514-29-1; CAS#35317-44-3

Biological target: Teniposide is a podophyllotoxin derivative and acts as a topoisomerase II inhibitor.
In vitro activity: The IC50 of teniposide (VM-26) against Tca8113 cells was 0.35 mg/l and that of CDDP was 1.1 mg/l. The morphological changes of Tca8113 cells were observed with fluorescence microscope and TEM. Apoptotic morphological feature could be found in the nucleus. Apoptotic rate of Tca8113 cells incubated with 5.0 mg/l of VM-26 for 72 hours was 81.67% and cells were arrested at S phase. However, when exposed to 0.15 mg/l of VM-26 for 72 hours, G2/M phase increased from 12.75% to 98.71%, while the apoptotic rate was 17.38%, which was lower than that exposed to 5.0 mg/l of VM-26.

In vivo activity: Teniposide at a dose of 0.5 mg/kg significantly increased the frequency of MNPCE. Additionally, teniposide significantly decreased the percent PCE, indicating a reduction in erythroblast proliferation most likely by mitotic arrest. A total of 148 MN from teniposide-treatment group were analysed by FISH and 69 (46.62%) MN of these were double labelled with centromere and telomere probes, indicating that they were formed by lagging chromosomes and reflecting an aneugenic activity of teniposide. Similarly, 77 (53.38%) of the induced MN were centromere negative, indicating that they were formed by acentric fragments and reflecting the clastogenic activity of teniposide. Since the centromere probe labelled mitotic chromosomes at both chromatids, it can be concluded that equal proportions of MN contained single chromatids (chromosome loss) and biarmed chromosomes (non-disjunction).
