MitoPBN
Based on 1 Customer Validation
MitoPBN is a AMPK/SIRT3/PGC-1α axis modulator, reactive oxygen species scavenger and mitochondrial function enhancer. MitoPBN increases the phosphorylation level of AMPK, restores SIRT3 expression and reverses the down-regulation of PGC-1α, thereby promoting mitochondrial biogenesis. MitoPBN regulates glucose metabolism, reduces blood glucose by inhibiting hepatic gluconeogenesis and increasing hepatic glucose uptake, while scavenging mitochondrial superoxide anion/hydrogen peroxide, maintaining membrane potential and increasing ATP production. MitoPBN also reduces cell apoptosis, improves sperm motility, survival rate and membrane integrity, but may induce reductive stress in cryopreserved sperm at high concentrations. MitoPBN is widely applicable to research related to diabetes and type 2 diabetes.

Biological Activity

SIRT3 |
MitoPBN (40 μmol/l; 24 h) upregulates the AMPK/SIRT3/PGC-1α axis in STZ-treated primary mouse hepatocytes by increasing phosphorylated PGC-1α, phosphorylated AMPK, total AMPK, SIRT3, and NRF1 protein levels[1].
MitoPBN (40 μmol/l; 24 h) restores mitochondrial number in H2O2-stressed primary mouse hepatocytes, which was reduced by oxidative stress[1].
MitoPBN (100-150 μmol/L; ≥7 days) supplementation of isolated Ghezel ram sperm cryopreservation extender significantly improves post-thaw sperm motility, membrane integrity, mitochondrial activity, viability, antioxidant capacity, and ATP content while reducing ROS levels, abnormal sperm, and apoptosis, with 150 μmol/L being the optimal concentration[2].
MitoPBN (1-100 μmol/l; 3 h) potently scavenges peroxyl and carbon-centered free radicals in a cell-free in vitro system, as demonstrated by H2O2 consumption and adduct formation[3].
MitoPBN (5-20 μmol/l; 24 h) protects STZ-stressed L02 liver cells from cytotoxicity, with greater efficiency than PBN, and liposomal encapsulation as Nano-MitoPBN significantly reduces the effective protective concentration[3].
MitoPBN (40 μmol/l) inhibits hypoxia-induced mitophagy in L02 liver cells by reducing protein expression of LC3B and ATG5[3].

Cell Line:Streptozotocin (HY-13753) -stressed L02 human liver cells
-
Concentration:5, 20 μm
-
Incubation Time:24 h
-
Result:Protected L02 cells from Streptozotocin (STZ)-induced cytotoxicity.
Showed lower protective efficiency than Nano-MitoPBN, with 5 μmol/l Nano-MitoPBN achieving a comparable effect to 40 μmol/l free MitoPBN.
Exhibited greater protective efficiency than PBN, requiring a lower concentration to rescue cell survival.
Free MitoPBN (2.5 mg/kg; i.p.; daily; 8 weeks) reduces random blood glucose levels and improves oral glucose tolerance in high-fat diet-induced type 2 diabetic C57BL/6J mice[3].

-
Dosage:100 µmol/L; 150 µmol/L; 200 µmol/L; 250 µmol/L
-
Administration:added to tris extender for semen dilution prior to cryopreservation
-
Result:Effects at 100 µM
Increased total motility to 52.36%, progressive motility to 24.82%, membrane integrity to 50.01%, mitochondrial activity to 46.16%, and sperm viability to 48.99%.
Elevated total antioxidant capacity (TAC) to 1.85 mmol/L and glutathione peroxidase (GPx) activity to 61.16 U/mg.
Decreased ROS levels to 2.95 ×103 cpm/106 sperm, abnormal sperm to 19.23%, and apoptotic sperm to 20.10%.
Increased straight-line velocity (VSL) to 55.24 µm/s and ATP content to 90 pmol/106 sperm.
Effects at 150 µmol/L (Optimal Dose)
Achieved highest total motility (54.16%), progressive motility (26.77%), membrane integrity (52.54%), mitochondrial activity (50.26%), and sperm viability (52.20%).
Maximized TAC to 1.93 mmol/L and GPx activity to 63.36 U/mg.
Reduced ROS levels to their lowest point at 2.80 ×103 cpm/106 sperm, with abnormal sperm at 18.82% and apoptotic sperm at 18.70%.
Reached peak average path velocity (VAP) of 68.82 µm/s, VSL of 55.24 µm/s, and maximum ATP content of 116.29 pmol/106 sperm.
Effects at Higher Concentrations (200 & 250 µmol/L)
200 µmol/L (Diminishing Returns):
Showed increased sperm viability (44.12%) and ATP content, with reduced apoptotic sperm (~25%), but offered no significant improvements in motility, membrane integrity, or antioxidant markers compared to the 100 and 150 µmol/L doses.
250 µmol/L (Ineffective):
Did not provide significant beneficial effects on measured sperm parameters relative to the control group.
