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. [67]
Etoposide, an epipodophyllotoxin. Epipodophyllotoxins are substances naturally occurring in the root of American Mayapple plant (Podophyllum peltatum). Some epipodophyllotoxin derivatives are currently used in the treatment of cancer. These include etoposide and teniposide. They act as anti-cancer drugs by inhibiting topoisomerase II. [1]
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 ...
Etoposide: a topoisomerase inhibitor from the group of epipodophyllotoxins; Prednisolone: a glucocorticoid hormone that can cause apoptosis and lysis of both normal and malignant lymphocytes; Oncovin, also known as vincristine: a vinca alkaloid that binds to the protein tubulin, thereby preventing the formation of microtubules and mitosis;
One mechanism of action for genotoxic carcinogens includes the formation of DNA adducts. Once the PAH compound enters an organism, it becomes metabolized and available for biotransformation. The biotransformation process can activate the PAH compound and transform it into a diol epoxide, [ citation needed ] which is a very reactive intermediate .
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.
Bacitracin is a polypeptide antibiotic derived from a bacterium, Bacillus subtilis, and acts against bacteria through the inhibition of cell wall synthesis. [6] It does this by inhibiting the removal of phosphate from lipid compounds, thus deactivating its function to transport peptidoglycan; the main component of bacterial cell membranes, to the microbial cell wall.
