 | Hazard Information | Back Directory |  | [Uses] 
 PE 22-28 is a TREK-1 inhibitor with IC50 value of 0.12 nM. PE 22-28 also is a 7 amino-acid peptide that is used as a core sequence for preparing analogs by chemical modifications and also by substitution of amino-acids. PE 22-28 can be used for the research of depression[1].
 |  | [in vivo] 
 
 PE 22-28 (i.p.; 3.0μg/kg) shows antidepressant property[1]. | Animal Model: | Na?ve male C57Bl/6J mice[1] |  | Dosage: | 3.0μg/kg |  | Administration: | Intraperitoneal |  | Result: | Showed a significant reduction of the immobility time, reduced significantly the latency to eat the food pellet, induced neurogenesis and improved the action duration. |
