Abstract
Metabolomic fingerprint of breast cancer cells treated with the antidiabetic drug metformin revealed a significant accumulation of 5-formimino-tetrahydrofolate, one of the tetrahydrofolate forms carrying activated one-carbon units that are essential for the de novo synthesis of purines and pyrimidines. De novo synthesis of glutathione, a folate-dependent pathway interconnected with one-carbon metabolism was concomitantly depleted in response to metformin. End-product reversal studies demonstrated that thymidine alone leads to a significant but incomplete protection from metformin's cytostatic effects. The addition of the substrate hypoxanthine for the purine salvage pathway produces major rightward shifts in metformin's growth inhibition curves. Metformin treatment failed to activate the DNA repair protein ATM kinase and the metabolic tumor suppressor AMPK when thymidine and hypoxanthine were present in the extracellular milieu. Our current findings suggest for the first time that metformin can function as an antifolate chemotherapeutic agent that induces the ATM/AMPK tumor suppressor axis secondarily following the alteration of the carbon flow through the folate-related one-carbon metabolic pathways.

Abstract
The concept of prodrugs has been successfully executed for life cycle management options of several approved drugs and drugs in development. In addition to imparting ideal biopharmaceutical properties, such as solubility, permeability and lipophilicity, some prodrug concepts have also enabled site-specific drug delivery, prolonged the duration of therapeutic effect and improved therapeutic index. The strategic inclusion of prodrug concept during drug discovery and early development process brings in some unique challenges. The communication provides balanced perspectives on the rational use and challenges of prodrug concept during the drug discovery and development process.
