Identification of chemosensitizers by drug repurposing to enhance the efficacy of cancer therapy
2020
Abstract The progressively rising drug resistance has driven the development of chemosensitizers, which aim to enhance the current chemotherapeutic efficacy through either quantitatively increasing intracellular drug concentration by inhibiting drug efflux, vesicle sequestration, and metabolic inactivation or qualitatively exerting concomitant effects on cellular regulation to promote apoptosis. Given the high failure rates and costs during standard drug development, drug repurposing represents an effective and economic approach for chemosensitizer identification. By applying drug repurposing, a wide range of existing clinic drugs including anticardiovascular agents, immunosuppressants, ant…
Silymarin and Cancer: A Dual Strategy in Both in Chemoprevention and Chemosensitivity
2020
Silymarin extracted from milk thistle consisting of flavonolignan silybin has shown chemopreventive and chemosensitizing activity against various cancers. The present review summarizes the current knowledge on the potential targets of silymarin against various cancers. Silymarin may play on the system of xenobiotics, metabolizing enzymes (phase I and phase II) to protect normal cells against various toxic molecules or to protect against deleterious effects of chemotherapeutic agents on normal cells. Furthermore, silymarin and its main bioactive compounds inhibit organic anion transporters (OAT) and ATP-binding cassettes (ABC) transporters, thus contributing to counteracting potential chemor…
