UsesA labelled semi-synthetic derivative of Podophyllotoxin. Antineoplastic.
UsesA semi-synthetic derivative of Podophyllotoxin. Antineoplastic.
UsesTeniposide 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.
IndicationsTeniposide (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.
DefinitionChEBI: 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.

Brand nameVumon (Bristol-Myers Squibb).
Therapeutic FunctionAntineoplastic
General DescriptionTeniposide 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 ActionsTeniposide (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 UseTeniposide is used in combination with other agents for the treatment of refractory childhood acute lymphoblastic leukemia.
Safety ProfilePoison by intraperitoneal and subcutaneous routes. An experimental teratogen. Human systemic effects by ingestion and intravenous route: anorexia, nausea or vomiting, leukopenia, agranulocytosis and aplastic anemia of the blood, bone marrow changes, and hair changes. Experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits very toxic fumes of SOx.
SynthesisTeniposide, [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) .
