Potent and selective peptide orexin OX1 receptor agonist (EC50 values are 8.29 and 187 nM for OX1 and OX2 receptors respectively). Truncated form of orexin A.
ML67-33 rapidly and reversibly affects K2P2.1 (TREK-1) (EC50s: 36.3 μM and 9.7 μM in cell-free and HEK293 cells, respectively). ML67-33 is a selective activator of temperature- and mechano-sensitive K2P channels.
FK 33-824 ,with similar actions to those of methionine enkephalin(ENKEPHALIN, METHIONINE),is a stable synthetic analog of that. Its effects can be reversed by narcotic antagonists such as naloxone.
JAY2-22-33, as a neuroprotective agent, can act by significantly reducing Aβ toxicity by delaying paralysis and improving cognitive performances in a transgenic mouse model of AD.
