HSK21542 significantly inhibits forskolin-induced cAMP accumulation in HEK-293 cells that stably expressed human κ opioid receptor with an EC50 of 2.41 pM.
HSK21542 displays no significant affinity against a broad panel of receptors, ion channels, transporters and enzymes, including MOR and DOR.
HSK21542 significantly inhibits acetic acid-, hindpaw incision- or chronic constriction injury-induced pain-related behaviors in animal models of pain
