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.

It was unknown if a mitochondria-targeted nitroxide (JP4-039) could augment potentially lethal damage repair (PLDR) of cells in quiescence. We evaluated 32D cl 3 murine hematopoietic progenitor cells which were irradiated and then either centrifuged to pellets (to simulate PLDR

We studied radioprotection and mitigation by mitochondrial-targeted Tempol (GS-nitroxide, JP4-039), in a mouse injury/irradiation model of combined injury (fracture/irradiation). Right hind legs of control C57BL/6NHsd female mice, mice pretreated with MnSOD-PL, JP4-039, or with amifostine were irradiated with single and

The acute lethality of total-body irradiation (TBI) involves damage to multiple organs, including bone marrow and intestine. Ionizing radiation mitigators that are effective when delivered 24 h or later after TBI include the anti-apoptotic drug, JP4-039 and the anti-necroptotic drug
Liang Wei et al.
Scientific reports, 8(1), 2072-2072 (2018-02-03)
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

Fanconi anemia (FA) is an inherited disorder characterized by defective DNA repair and cellular sensitivity to DNA crosslinking agents. Clinically, FA is associated with high risk for marrow failure, leukemia and head and neck squamous cell carcinoma (HNSCC). Radiosensitivity in
