(D-ALA2)-LEUCINE ENKEPHALIN-ARG Usage And Synthesis

Uses

Dalargin is a potent δ-opioid receptor agonist. Dalargin mitigates Gentamicin (HY-A0276)-induced cell death. Dalargin shows nephroprotective effects on Gentamicin-induced kidney injury. Dalargin shows antiulcer activity[1][2][3].

in vivo

Dalargin (25, 50 μg/kg; i.p.) shows nephroprotective effects on gentamicin-induced kidney injury in rats[2].

Animal Model:290-350 g, White male rats[2]
Dosage:25, 50 μg/kg
Administration:I.p. (3 h before each gentamicin injection)
Result:Mitigated gentamicin-induced acutekidney injury, attenuated ROS generation and oxidative stress, alleviated histopathological changes in a renal tissue.

IC 50

δ Opioid Receptor/DOR
