Application
Efaproxiral Sodium: Developed as an Allosteric Modifier of Hemoglobin and a Radiation Sensitizer
Efaproxiral sodium (RSR 13 sodium), an analogue of the antilipemic agent bezafibrate [B3346], was developed as an allosteric modifier of hemoglobin1,2) and a radiation sensitizer.3) In the 2000s, efaproxiral sodium was tested in a clinical trial to increase the efficacy of certain chemotherapy agents which have reduced efficacy against hypoxic tumors, and can thus be made more effective by increased offloading of oxygen from hemoglobin-bound oxygen into the tumor tissues.4) But the clinical trial was dropped out in Phase III trials. In 2009, Efaproxiral was added to the World Anti-Doping Agency (WADA) list of Prohibited Substances as an artificially enhancer of the uptake, transport or delivery of oxygen.5) (The product is for research purpose only.)
