- W3029797675 abstract "e15599 Background: Targeting cancer cell metabolism has gained attention as a future strategy to fight cancer. A characteristic of tumor cells is the elevated aerobic glycolysis for energy production. It has been shown that 2-deoxy-D-glucose (2DG) inhibits glycolysis and induces apoptotic cell death in different tumor types. The anti-diabetic drug metformin has been used in combination to enhance the inhibitory effect. So far, the attempts to combine both compounds in a clinical setting have been limited by the requirement of concentrations higher than those accessible in blood plasma of human beings. Deep eutectic solvents (DES) are solvent mixtures prepared from hydrogen bond donors and acceptors, wherein pharmaceutically active compounds can also be one of the components. Besides having unique physicochemical properties, DESs have been reported to demonstrate or enhance anticancer properties. Methods: We developed a DES mixture from 2DG and MET using a method based in mechanical grinding. We investigated the anticancer activity of conventional and DES mixtures of MET and 2DG, and used the mixtures to inhibit the growth, migration and invasion of cancer cells, and induce cell cycle arrest in vitro. Results: MET and 2DG, alone and in combination, induced apoptosis in the H460, SKOV-3, MDA-MB-231 and HCC1806 (TNBC) cell lines. Induction of apoptosis was further quantified by measurement of the loss of mitochondrial membrane potential and cleavage of PARP. DES mixtures had the highest impact on cell viability, exceeding the effect of 2DG/MET as single agents or combinations at all clinically relevant concentrations. The DES mixture with the lowest concentration to induce apoptosis consisted of 100 µM 2DG and 200 µM MET. A conventional solution with similar concentrations showed no activity. Conclusions: We developed a DES from 2DG/MET, which significantly reduced the viability of several types of cancer cells, surpassing the effect of single components or mixtures. The DES does not necessitate the use of additional solvents and could be used to develop clinical applications for targeting cancer cell metabolism." @default.
