reactive oxygen species (ros)

Elamipretide (MTP-131) is a mitochondria-targeted antioxidant tetrapeptide (D-Arg-dimethylTyr-Lys-Phe-NH2) that reduces toxic reactive oxygen species (ROS) production and stabilizes cardiolipin, with blood-brain-barrier permeability. It is a potential therapeutic agent in the rare disease of Barnes syndrome.

HNGF6A TFA, a humanin analogue, enhances glucose-stimulated insulin secretion and glucose metabolism, offering potential for diabetes research. It also inhibits ROS (Reactive Oxygen Species) production under oxidative stress and may prevent endothelial dysfunction and atherosclerosis in vivo [1] [2].

Pinealon is a 3-amino acid peptide that shows neuroprotective properties by preventing reactive oxygen species (ROS) accumulation and suppressing the activation of ERK 1 2. Pinealon stimulates the functional activity of the main cellular elements of brain tissue, reduces the level of spontaneous cell death, and protects rat offspring from prenatal hyperhomocysteinemia [1] [2] [3].

cPcAMP1 26, an antimicrobial peptide, exhibits potent bactericidal activity against A. hydrophila and S. aureus by inducing depolarization of the bacterial plasma membrane and elevating intracellular ROS (Reactive Oxygen Species) levels [1].

Phoenixin-14 TFA (PNX-14) is a blood-brain barrier (BBB)-penetrable neuropeptide with anxiolytic, cardioprotective, and neuroprotective properties. It modulates pituitary gonadotrophin release by enhancing gonadotropin-releasing hormone (GnRH) receptor mRNA expression and promotes insulin secretion. Additionally, PNX-14 TFA protects against ischemia reperfusion (IR) injury in mice and combats oxidative stress by diminishing reactive oxygen species (ROS) and elevating glutathione (GSH) levels [1] [2] [3].

Dynamin-related protein 1 (Drp1) inhibitor, inhibits Drp1 GTPase activity. Displays no effect on dynamin 1 or other mitochondrial dynamics-related proteins. Inhibits mitochondrial fission, dysfunction and reactive oxygen species (ROS) production in vitro.

TAT-MKK3b is a peptide inhibitor of p38 and can inhibit the phosphorylation of p38. It has renal targeting capabilities, is effective in scavenging reactive oxygen species (ROS), and can alleviate ferroptosis (ferroptosis). TAT-MKK3b may improve acute kidney injury and its progression to chronic kidney disease.

Corza6 is a potent and selective peptide inhibitor of the human voltage-gated proton channel (hHv1). It binds to the external voltage sensor domain (VSD) loop in hHv1 at a resting membrane potential (RMP) of natural hyperpolarization in mammalian cells with a Kd of approximately 1 nM. Corza6 facilitates sperm capacitation and permits sustained production of reactive oxygen species (ROS) in leukocytes (WBC).
