Diabetes mellitus occurrence has been associated to the modification of the physiological levels of glucose and is often accompanied by several long-term complications, namely neuropathy, nephropathy, retinopathy, cataract, and cardiovascular. Aldose reductase (AR) is an enzyme of aldoketo reductase super-family that catalyzes the conversion of glucose to sorbitol in the polyol pathway of glucose metabolism. In this context, aldose reductase inhibitors (ARIs) have received much attention worldwide.

The peroxisome proliferator activated receptors (PPARs) are type II nuclear hormone receptors that regulate a number of processes in living systems, such as metabolism of carbohydrates and fatty acids, growth and differentiation of cell, and inflammatory reactions. Alpha, gamma and delta are the three distinct isoforms of PPAR.

Conversion of glucose to glucose-6-phosphate by GK promotes glycogen synthesis in liver hepatocytes, and insulin release in the pancreatic β-cells. Small molecules called glucokinase activators (GKAs) which bind to an allosteric activator site of the GK enzyme have indeed been discovered and developed, and thus hold great promise as new, effective and safe antidiabetic agents.
