Molecular mechanisms of etoposide

چکیده
Etoposide derives from podophyllotoxin, a toxin found in the American Mayapple. It was first synthesized in 1966 and approved for cancer therapy in 1983 by the U.S. Food and Drug Administration (Hande, 1998[25]). Starting from 1980s several studies demonstrated that etoposide targets DNA topoisomerase II activities thus leading to the production of DNA breaks and eliciting a response that affects several aspects of cell metabolisms. In this review we will focus on molecular mechanisms that account for the biological effect of etoposide.

Cross-resistance to Vincristin and Etoposide in a sub line of the human breast cancer T47D cells selected for Adriamycin-resistance
Breast cancer is one of the most common malignancies among women. Although chemotherapy remains a major therapeutic approach to treat cancers, drug therapy often fails for several reasons, particularly the drug resistance. Resistance to multiple chemotherapeutic agents is one of the most important problems in the treatment of different types of cancers. Therefore, in this study a resistant sub ...

متن کاملEnhanced Permeability of Etoposide across Everted Sacs of Rat Small Intestine by Vitamin E-TPGS
Etoposide, a widely used anticancer drug, exhibits low and variable oral bioavailability mainly because of being substrate for the efflux transporter, P-glycoprotein (P-gp). Therefore, the present study was aimed to investigate the effect of D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) and PEG 400 as P-gp inhibitors on the intestinal absorption of etoposide. Everted sacs of rat smal...
متن کاملThe effect of podophyllotoxin as an inducer of apoptosis using molecular docking method
Background and aim: Podophyllotoxin is used as one of the main treatments for genital warts. It is a precursor of etoposide and teniposide, which is used in the treatment of various cancers. Despite a large number of cancer studies, the exact mechanism of podophyllotoxin remains unknown. Chemotherapy drugs reduce cancer cells by inducing apoptosis. The regulation of the apoptotic pathway has be...
