生物活性

Efaproxiral-d6 (RSR13-d6) is the deuterium labeled Efaproxiral. Efaproxiral (RSR13) is a haemoglobin (Hb) synthetic allosteric modifier, decreases Hb-oxygen (O2) binding affinity and enhances oxygenation of hypoxic tumours during radiation therapy[1][2].

体外研究
(In Vitro)

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.

生物活性

Efaproxiral sodium (RSR13 sodium) is a synthetic allosteric modifier of haemoglobin (Hb), decreases Hb-oxygen (O2) binding affinity and enhances oxygenation of hypoxic tumours during radiation therapy. in vitro: Efaproxiral increases oxygen levels in hypoxic tumor tissues by binding non-covalently to the hemoglobin tetramer and decreasing hemoglobin-oxygen binding affinity. Increasing tumor oxygenation reduces tumor radioresistance. Efaproxiral can enhance the oxygenation of hypoxic tumours and function as a radiation sensitiser, increasing the effectiveness of RT.

生物活性

IC50 & Target

haemoglobin (Hb)[1]
体外研究
(In Vitro)

Efaproxiral binds to only one pair of symmetry-related sites in the Hb central water cavity[2].
Efaproxiral readily crosses the red cell membrane in the presence of serum albumin solutions[2].
Efaproxiral is not inhibited from entering erythrocytes in the presence of an anion-channel blocking agent (DIDS)[2].

体内研究
(In Vivo)

Efaproxiral (150 mg/kg, i.p.) increase tumor oxygenation，and increase the tumor growth inhibition of radiotherapy over 5 days of treatment[3].
Efaproxiral reduces hemoglobin-oxygen binding affinity, which facilitates oxygen release from hemoglobin into surrounding tissues and potentially increases the pO(2) of the tumors[4]

Animal Model: Female C3H/HEJ mice (18–20 g), with radiation-induced fibrosarcoma tumor (RIF-1) cells xenograft[3]
Dosage: 150 mg/kg
Administration: Intraperitoneal injection; prior to X Irradiation (4 Gy/day), for 5 days
Result: Significantly increased tumor oxygenation by 8.4 to 43.4 mmHg within 5 days, with maximum increases at 22–31 minutes after treatment.
