To examine the response of the metabolic phenotype to diabetes and antidiabetic medication is of great importance in drug discovery and patient therapy, since it allows the determination of new drug targets and improves the understanding of the underling drug mechanisms. Metabolomics were used to study the antidiabetic drug action in peripheral organs (testis, lung, adrenal gland, cerebellum) and on the systemic level (plasma). Therefore, two single drugs (metformin, SGLT2-inhibitor), and a combination of both drugs were administered to a diabetic mouse model, as acute and sub-chronic treatment, respectively. The combined sub-chronic treatment with both drugs normalized blood glucose levels. Beside this primary readout, several metabolites which are known to be related to diabetes and metabolic syndrome, responded to the treatment. Citrulline, amino adipic acid, specific phosphatidylocholines, lysophosphatidylcholines and hydroxy-sphingomyelins were altered on the systemic level. Site specific response was observed for long-chain hydroxylated acylcarnitines in the lung, histamine and carnosine in cerebellum. These metabolites and the underlying biochemical pathways seem to play a crucial role in the improvement of diabetes triggered by the combination treatment.
