Biochem/physiol Actions

JP4-039 is an electron-/reactive oxygen species (ROS)-scavenging GS-nitroxide composed of 4-amino-TEMPO and a truncated gramicidin S (GS) mitochrondria-targeting sequence. JP4-039 is a superior irradiation mitigator than XJB-5-131 (33% vs. 20% mice survial rate on day 35 with respective compound; 23.6 μmol/kg iv. 24 hr post 9.5 Gy whole body irradiation), while displaying weaker anti-ferroptotic potency (EC50 = 3.58 μM/1.27 μM against 10 μM erastin-/2 μM RSL3-induced HT-1080 ferroptosis vs. 114 nM/68 nM with XJB-5-131) due to lower lipophilicity & mitochondria enrichment. Typical dosing range: 40 nM-10 μM in cultures and 10-20 mg/kg in mice (im., ip., iv.) in vivo.

Total body irradiation (TBI) leads to dose- and tissue-specific lethality. In the current study, we demonstrate that a mitochondrion-targeted nitroxide JP4-039 given once 24 hours after 9-10 Gy TBI significantly improves mouse survival, and the recovery of intestinal barrier, differentiation and stem

Total-body irradiation (TBI) doses in the range of 2-8 Gy are associated with a drop in peripheral blood counts, decreased bone marrow cellularity, and hematopoietic syndrome. Radiation mitigators must be safe for individuals likely to recover spontaneously. Female C57BL/6HNsd mice

The mitochondrial targeted GS-nitroxide, JP4-039, is an effective total body irradiation (TBI) mitigator when delivered intravenously (IV) up to 72 h after exposure. Effective systemic and localized administration to oral cavity/oropharynx and esophagus has been demonstrated. The objective of the
