Cysteinylglycine (L-Cysteinylglycine; Cys-Gly) is a dipeptide formed by the peptide bond linkage between cysteine (Cysteine) and glycine (Glycine). Cysteinylglycine is an important metabolic intermediate in the human body, mainly derived from the degradation of glutathione (GSH). Cysteinylglycine reduces ferric iron to ferrous iron, drives the redox cycle of iron, generates reactive oxygen species (ROS), stimulates oxidative reactions, induces lipid peroxidation of human plasma LDL lipoproteins, and causes oxidative damage to DNA bases. Cysteinylglycine can be used as a biomarker to evaluate ischemic heart disease, breast cancer and other conditions.

MOTS-c (human) is a mitochondrial-derived peptide that modulates the AMPK/PGC-1α pathway to enhance insulin sensitivity. MOTS-c (human) inhibits the folate cycle and de novo purine synthesis, increases AICAR levels to activate AMPK, and then regulates the Nrf2/Keap1 antioxidant pathway and inhibits the NF-κB inflammatory pathway, while promoting mitochondrial biogenesis and energy metabolism. MOTS-c (human) has the effects of improving glucose and lipid metabolism, anti-oxidative stress, anti-inflammatory and neuroprotection, and can be used in the study of type 2 diabetes, traumatic brain injury, inflammatory diseases and aging-related metabolic disorders.

Glycylglycine is a non-selective glycylglycine dipeptidase substrate and iNOS inhibitor. Glycylglycine can cross the cell membrane by passive diffusion and is hydrolyzed to glycine in the cell, participating in energy metabolism and antioxidant processes. Glycylglycine promotes spermatogonial stem cells (SSCs) proliferation, inhibits astrocyte overactivation and reduces nitric oxide (NO) release, while upregulating the expression of neurotrophic factors (such as PDGFA, FGF2, CNTF) to support nerve myelin repair. Glycylglycine can be used to study male reproductive biology (such as SSCs proliferation regulation) and neurodegenerative diseases (such as neuroprotective mechanisms in multiple sclerosis).

MOTS-c (human) acetate is a mitochondrial-derived peptide that modulates the AMPK/PGC-1α pathway to enhance insulin sensitivity. MOTS-c (human) acetate inhibits the folate cycle and de novo purine synthesis, increases AICAR levels to activate AMPK, and then regulates the Nrf2/Keap1 antioxidant pathway and inhibits the NF-κB inflammatory pathway, while promoting mitochondrial biogenesis and energy metabolism. MOTS-c (human) acetate has the effects of improving glucose and lipid metabolism, anti-oxidative stress, anti-inflammatory and neuroprotection, and can be used in the study of type 2 diabetes, traumatic brain injury, inflammatory diseases and aging-related metabolic disorders.
