Biological Activity
| Targets | κ Opioid Receptor/KOR |
| ln Vitro | Dynorphin A (1-13) exposure (33 μM) causes a discernible destruction of neuronal morphology at 16 hours, and a substantial loss of neuronal viability at 4 hours. Individual neurons' acute [Ca2+]i increases in response to dynorphin A (1–13) exposure are comparable to those observed following acute NMDA treatment.Over time, dynorphin A (1–13) (100 μM) exposure consistently results in a notable loss of neurons[1]. |
| ln Vivo | Dynorphin A (1-13) exposure (33 μM) resulted in a significant loss of neuronal viability at 4 hours and a significant disruption of neuronal morphology at 16 hours. Exposure to dynorphin A (1-13) results in a dramatic increase in [Ca2+]i in single neurons, similar to the increase seen with acute NMDA treatment. Sustained exposure to dynorphin A (1-13) (100 μM) results in significant neuronal loss over time [1]. |
