Web8.1.2 Hexokinase inhibitors HK-II, a rate-limiting enzyme in the glycolytic pathway influencing also the pentose phosphate pathway, contributes to the accelerated glucose metabolism in cancer. Several HK-II inhibitors have been developed after the discovery of the glucose analog 2-deoxy- d -glucose (2-DG).

WebHexokinase-1 (HK1) is an enzyme that in humans is encoded by the HK1 gene on chromosome 10. Hexokinases phosphorylate glucose to produce glucose-6-phosphate (G6P), the first step in most glucose metabolism pathways. This gene encodes a ubiquitous form of hexokinase which localizes to the outer membrane of mitochondria.
