BIOCHEMICAL MECHANISMS OF ETOPOSIDE; UPSHOT OF CELL DEATH
Etoposide is an antineoplastic agent employed for healingvarious malignancies in human. It is a semi-synthetic derivative of podophyllotoxin and was introduced in 1971. The primary mode of action of etoposide is the inhibition of the function of the enzyme topoisomerase II. It stabilizes DNA-enzyme complex, and accumulation of this complex enhances the probability of double-stranded DNA breaks. Ho...
