A semi-synthetic derivative of Podophyllotoxin. Antineoplastic. | [Uses]
Teniposide is a podophyllotoxin derivative that causes dose-dependent single- and double-stranded breaks in DNA by inhibiting topoisomerase II. Its cytostatic effects are related to its ability to stabilize the DNA-topoisomerase II complex during DNA replication, inducing DNA damage and cellular apoptosis. Teniposide has been widely used in the treatment of various cancers including, small cell lung cancer, malignant lymphoma, breast cancer, oral squamous cell carcinoma, and acute lymphoblastic leukemia. | [Definition]
ChEBI: A furonaphthodioxole that is a synthetic derivative of podophyllotoxin with anti-tumour activity; causes single- and double-stranded breaks in DNA and DNA-protein cross-links and prevents repair by topoisomerase II binding. | [Indications]
Teniposide (VM-26, Vumon) is closely related to etoposide
in structure, mechanisms of action and resistance,
and adverse effects. It is more lipophilic and approximately
threefold more potent than etoposide. Its major
uses have been in pediatric cancers, particularly in acute
lymphoblastic leukemias. | [Manufacturing Process]

Antineoplastic | [General Description]
Teniposide is available in 50-mg ampules with Cremophor ELfor IV administration in the treatment of acute lymphoblasticleukemia (ALL). The agent is more potent as an inhibitor oftopoisomerase II. The pharmacokinetics of teniposide issimilar to that of etoposide; however, the more lipophilic teniposideis more highly protein bound (99%) and less isexcreted unchanged in the urine (10%–20%). There is alsogreater overall metabolism of teniposide; however, CYP3A4-mediated conversion to the active catechol is slower comparedwith etoposide. Elimination occurs primarily in the urine witha terminal elimination half-life of 5 hours. | [Biochem/physiol Actions]
Teniposide (VM-26) is a Topoisomerase II inhibitor with antitumor activity. Teniposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA, inducing breaks in double stranded DNA and preventing repair. | [Clinical Use]
Teniposide is used in combination with other agents for the treatment of refractory childhood acute lymphoblastic leukemia. | [Synthesis]
Teniposide, [5R-(5|á,5a|?,8a|á,9|?)]-9-[4,6-O-(2-thienylmethylene)-|?-D-glucopyranosyl)oxy]- 5,8,8a,9-tetrahydro-5-(4-hydroxy-3,5-dimethoxyphenyl)furo[3,4: 6,7]-naphtho[2,3-d]-1,3-dioxol-6(5aH)-one (30.4.9), is basically synthesized by an analogous scheme
from 4-benzyloxy-4-desmethylepipodophyllotoxin (30.4.6), which is esterified by 2,3,4,6-
tetra-O-acetyl-|?-D-glucose in the presence of boron trifluoride etherate, giving a glycoside
30.4.7. The acetyl and benzyloxycarbonyl protecting groups in this molecule are removed by
succesive use of zinc acetate and sodium methoxide, and then by subsequent hydrogen reduction, which forms the diol 30.4.8. The resulting diol is then transformed into the corresponding acetal 2-formylthiophene, which is the desired teniposide (30.4.9) .
