| Hazard Information | Back Directory | [Uses]
GBT 440 is a potent allosteric effector of sickle cell hemoglobin (Hb) that increases the affinity of Hb for oxygen and inhibits its polymerization when subjected to hypoxic conditions. | [Biological Activity]
Voxelotor improves the abnormal aggregation of hemoglobin under hypoxic conditions, which is the main cause of sickle cell disease-related red blood cell dysfunction, by forming a Schiff base with the N-terminal valine of the hemoglobin alpha chain, increasing the affinity of sickle cell hemoglobin for oxygen and preventing its aggregation. | [Synthesis]
