biological activity
Tyr-Gly-Gly-Phe-Met-OH can regulate human immune function and inhibit tumor growth by binding to opioid receptor.
target
Opioid Receptor.
in vitro study
Methionine enkephalin (MENK), an endogenous neuropeptide has a crucial role in both neuroendocrine and immune systems. MENK is believed to have an immunoregulatory activity to have cancer biotherapy activity by binding to the opioid receptors on immune and cancer cells. MENK may also change the tumor microenvironment by binding to opioid receptor on or in cancer cells. All of these mechanisms of action have biologic significance and potential for use in cancer immunotherapy. Furthermore, they reveal a relationship between the endocrine and immune systems.
production method
using L-tyrosine, glycine, L-phenylalanine and L-methionine as raw materials, the side chains of amino acids with side chains in amino acids are protected by protective agents according to their characteristics, then condensation reaction is carried out in the presence of polypeptide condensing agent, and then the protective agent is removed and purified.
