ARA-290 Acetate CAS 1208243-50-8

ARA-290 Acetate is a polypeptide derived from erythropoietin, which has analgesic and tissue protective effects in many diseases such as diabetes and cancer. The analgesic effect of ARA 290 is mediated by its anti-inflammatory and immunomodulatory functions, or more specifically, high-quality Cibinetide powder is down-regulated by targeting innate repair receptor (IRR) to relieve neuropathic pain.

What is the pharmacological action of ARA-290 Acetate?

Poziotinib is a polypeptide derived from helix B of erythropoietin receptor binding domain. It is composed of 11 amino acids and does not retain the function of promoting erythropoiesis. According to relevant news reports, ARA290,Cibinetide is beneficial in many clinical applications, such as diabetes, sports injuries and sarcoidosis. In addition, ARA 290 can also protect cartilage tissue from secondary injury and repair the damaged tissue. Researchers believe that this may be because ARA-290 Acetate can specifically target the innate repair receptor (IRR) and down-regulate the inflammation of the injured site. But at present, the evidence of this inference is relatively thin, and more research is needed to determine it.

What is the new development of ARA-290 Acetate in the treatment of pain?

According to recent pain research, neuropathic pain refers to a state in which pain fibers in the somatic sensory system are affected by diseases or tissue injuries. Common symptoms include hyperalgesia and allodynia. Hyperalgesia is characterized by increased pain sensitivity, while allodynia is characterized by pain response to usually painless stimuli. Common diseases that can cause neuropathic pain include spinal cord injury, multiple sclerosis, diabetes, as well as cancer and chemotherapy for treating cancer. In the peripheral somatosensory system, neuropathic pain is usually caused by abnormal spontaneous activity of sensitized pain fibers after injury. In the central nervous system, its mechanism is more complicated, which may involve the increase of the sensitivity of spinal cord neurons caused by the phosphorylation of N-Methyl-D-aspartic acid (NMDA) subunit and the weakening of the inhibitory effect of intermediate neurons. Besides nervous system abnormalities, inflammation also plays an important role in the generation and maintenance of neuropathic pain. ARA-290 Acetate is generally believed to inhibit inflammation by targeting the innate repair receptor (IRR), thus alleviating neuropathic pain. However, it is still unclear whether it has direct analgesic effect on the central and peripheral nervous systems, and whether it directly acts on pain receptors has not been verified.
In recent years, the immune system has been proved to play an important role in pain transmission, and some immune molecules can directly activate peripheral pain fibers. These latest findings prompt us to speculate that ARA 290 may have a direct effect on transient receptor protein channels (such as TPRV1-4, TPRM8 and TRPA1), because these channels are responsible for most pain perception.
Through calcium imaging, genetic engineering HEK cells and behavioral analysis, researchers have proved that ARA 290 specifically inhibits and increases the threshold of TPRV1 channel. At the same time, we also found that ARA-290(Cibinetide) acetate can inhibit the calcium ion activity of TRPV1 in dorsal root ganglion (DRG) and dorsal root ganglion (TG) neurons induced by capsaicin and HEK cells overexpressing TRPV1. This inhibitory effect of ARA 290 can be extended to alleviate the behavioral allergic reaction induced by capsaicin in mice, which is particularly helpful in the clinical practice of pain treatment, because the pain relief of peripheral sensory system may be a ray of light for patients who have to rely on drug abuse and central regulation changes to endure pain in the future.

Is the ARA-290 Acetate potentially harmful?

ARA290/Pozotinib is a specific erythropoietin/CD131 heteroreceptor agonist. However, it is worth noting that there are many side effects when combined with conventional drugs such as recombinant human erythropoietin (rhEPO) in clinical practice. We have not found any significant side effects in animal toxicity and clinical application studies in human patients, so the current mainstream attitude is to affirm its safety. In addition, the half-life of ARA-290 Acetate is relatively short, minimizing the possibility of tissue exposure to high concentrations of drugs, which is very friendly for the treatment of some more severe patients. Especially recent studies have shown that ARA-290(Cibinetide) acetate can improve neuropathological symptoms and alleviate neuropathic pain, which may allow it to replace the recently popular drug rehabilitation and pain relief products and occupy a place.
