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.

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 ...
Lipinski's rule of five, also known as Pfizer's rule of five or simply the rule of five (RO5), is a rule of thumb to evaluate druglikeness or determine if a chemical compound with a certain pharmacological or biological activity has chemical properties and physical properties that would likely make it an orally active drug in humans.
For example, MDMA may make negative cognition worse. This means that a positive experience is not a guarantee and can be contingent on aspects like the setting and the patient's expectations. [ 46 ] Additionally there is no clear model of the psychopharmacological means for a positive or negative experience. [ 46 ]
The drug methotrexate (bottom) is an antimetabolite that interferes with the metabolism of folic acid (top). An antimetabolite is a chemical that inhibits the use of a metabolite, which is another chemical that is part of normal metabolism. [1]
The most effective treatment for severe (grade III–IV) encephalopathy is an intravenous solution of methylene blue, which appears to shorten the duration of encephalopathy; the exact mechanism of action of methylene blue is unclear. In some cases, methylene blue may be used as a prophylaxis before further doses of ifosfamide are administered.
However, there are some differences when it comes to typical and atypical antipsychotics. For example, atypical antipsychotic medications have been seen to lower the neurocognitive impairment associated with schizophrenia more than conventional antipsychotics, although the reasoning and mechanics of this are still unclear to researchers.
