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.

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 .
A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor. [3] Receptor sites have specific affinities for drugs based on the chemical structure of the drug, as well as the specific action that occurs there.
David E. Nichols in 1986 rejected this initial terminology and adopted, instead, the term entactogen, meaning "producing a touching within", to denote this class of drugs, asserting a concern with the potential for improper association of the term empathogen with negative connotations related to the Greek root πάθος páthos ("suffering ...
A mechanism of action of a chemical could be "binding to DNA" while its broader mode of action would be "transcriptional regulation". [3] However, there is no clear consensus and the term mode of action is also often used, especially in the study of pesticides, to describe molecular mechanisms such as action on specific nuclear receptors or ...
Ethogenics (/ ˌ iː θ ə ˈ dʒ ɛ n ɪ k s /; "the study of behavior as generated by persons who exhibit a character, an ethos", [1] from Greek ἦθος ethos, "custom, character" and γένος genos, "birth, generation") is an interdisciplinary social scientific approach that attempts to understand the systems of belief or means through which individuals attach significance to their ...
No systematic interaction studies are available. The enzyme inducers phenobarbital and phenytoin have been found to lower its blood plasma concentrations. [4] Theoretically possible interactions include increased plasma concentrations when combined with sodium salicylate, sulfamethizole or tolbutamide, which displace teniposide from plasma protein binding, at least in vitro.
