摘要：
While drug resistance appears to be an inevitable problem of an increasing number of anticancer drugs in monotherapy, combination drug therapy has become a prosperous method to reduce the administered total drug dosages as well as overcome the drug resistance of carcinoma cells. Curcumin, considered to possess multi-faceted roles in cancer treatment according to its multiple anti-neoplastic mechanisms as a depressor of chemo-resistance, can significantly facilitate its anti-cancer functions and improve therapeutic effects via combination usage with a variety of other drugs with different reaction mechanisms. To explore this possibility, four anti-cancer chemotherapeutic agents that all possess a certain degree of drug resistance problems, including three tyrosine kinase inhibitors (erlotinib, sunitinib and sorafenib) that are acting on different cell pathways and a typical anticancer drug doxorubicin, were combined with curcumin individually to examine the synergistic anti-tumor effect both and . Results revealed that sunitinib combined with curcumin at the molar ratio of 0.46 yielded the most potent synergistic effect , and was therefore chosen for further animal evaluation. To further enhance the anti-cancer effect, bovine serum albumin (BSA) nanoparticles were utilized as a carrier to deliver the selected drug combination . Preliminary findings confirmed our hypothesis of being able to maintain a similar injected drug ratio for prolonged time periods in tested animals by our approach, thereby maximizing the therapeutic potency yet minimizing the toxicity of these drugs. This work could open up a new avenue on combination drug therapy and realization the clinical utility of such drugs.
