HNG ([Gly14]-Humanin) 10mg

Description

HNG, formally designated [Gly14]-Humanin or S14G-Humanin, is a synthetic analog of Humanin,  a mitochondrial-derived peptide (MDP) that exists as either a 21-amino-acid form (mitochondrial translation) or a 24-amino-acid form (cytoplasmic translation). The synthetic 24-amino-acid form (MAPRGFSCLLLLTSEIDLPVKRRA) is the most widely studied in preclinical research in the context of Alzheimer’s disease.

HNG differs from native Humanin by a single amino acid substitution at position 14, where serine is replaced with glycine. This structural modification has been shown in preclinical studies to confer approximately 1,000-fold greater neuroprotective potency compared to the parent molecule. 

Key Characteristics

Originally derived from the 16S ribosomal RNA region of mitochondrial DNA, Humanin and its analogs represent a class of mitochondrial-derived peptides. They are investigated for their roles in cellular stress response, apoptosis regulation, and metabolic signaling. 

HNG has been studied across a range of in vitro and in vivo preclinical models, with data pointing to interactions involving anti-apoptotic pathways, mitochondrial function preservation, and neuroimmune modulation. The compound’s enhanced potency profile relative to native 

BC9’s HNG is supplied as a lyophilized powder in a 10mg research vial, manufactured to rigorous purity standards and intended strictly for qualified researchers operating within controlled laboratory environments. 

Possible Research Applications

• Neuroprotection & Ischemia Research  

Preclinical findings indicate HNG may attenuate neuronal apoptosis following ischemic insult, with rodent cerebral ischemia/reperfusion models demonstrating reduced infarct volume and improved neurological deficit scores in HNG-treated research subjects via PI3K/Akt pathway activation.

• Traumatic Brain Injury (TBI) Models

In preclinical data from research models suggest HNG may improve morphological and functional outcomes post-injury.

• Retinal Neurodegeneration & AMD Modeling

Preclinical research study suggests HNG may modulate angiogenesis and neurodegeneration marker protein levels.

• Metabolic & Mitochondrial Stress Research 

Preclinical evidence suggests HNG may interact with IGF-1 signaling and the trimeric receptor complex (CNTFR/gp130/WSX-1) to influence cellular energy metabolism and oxidative stress responses in research models, with investigators exploring its potential relevance to aging-associated metabolic dysregulation.
