Etoposide is a semisynthetic derivative of podophyllotoxin from the rhizome of the mayapple (or "American mandrake", Podophyllum peltatum). More specifically, it is a glycoside of podophyllotoxin with a D - glucose derivative.
Etoposide, a semi-synthetic derivative of epipodophyllotoxin is commonly used to study this apoptotic mechanism and include: Etoposide; Teniposide; Both etoposide and teniposide are naturally occurring semi-synthetic derivatives of podophyllotoxins and are important anti-cancer drugs that function to inhibit TopII activity.

Etoposide: IV, PO: Topoisomerase II inhibitor. Testicular cancer, ovarian cancer, lung cancer, acute myeloid leukaemia, lymphomas and sarcomas: Myelosuppression, hypersensitivity reactions, Stevens–Johnson syndrome (rare), peripheral neuropathy (uncommon) and secondary malignancies (especially acute myeloid leukaemia). Teniposide: IV
The cytotoxic antibiotics are a varied group of drugs that have various mechanisms of action. The common theme that they share in their chemotherapy indication is that they interrupt cell division . The most important subgroup is the anthracyclines and the bleomycins ; other prominent examples include mitomycin C and actinomycin .
In some literature articles, the terms "mechanism of action" and "mode of action" are used interchangeably, typically referring to the way in which the drug interacts and produces a medical effect. However, in actuality, a mode of action describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living ...
A hypomethylating agent (or demethylating agent [1]) is a drug that inhibits DNA methylation: the modification of DNA nucleotides by addition of a methyl group.Because DNA methylation affects cellular function through successive generations of cells without changing the underlying DNA sequence, treatment with a hypomethylating agent is considered a type of epigenetic therapy.
Physiological antagonism describes the behavior of a substance that produces effects counteracting those of another substance (a result similar to that produced by an antagonist blocking the action of an agonist at the same receptor) using a mechanism that does not involve binding to the same receptor.
The drug, a macrolide (polyhydroxylated lactone), is a member of a structural diverse class of compounds called polyketides with notable chemical mechanism of action. It stabilizes the microtubules of target cells, essentially arresting them at a specific stage in the cell cycle and halting cell division.
