Product Data
Biological target:
SKF-75670 HBr displays antagonist activity in vitro and agonist activity in vivo.
In vitro activity:
To be determined
In vivo activity:
D1 partial agonists, such as SKF-75670, can act as functional cocaine antagonists and may be viable candidate medications for the management of cocaine addiction. When administered in combination with cocaine, D1 agonists displaying relatively low efficacy (SKF 38393, SKF 75670) attenuated both the rate-altering effects of cocaine on fixed-ratio responding and the discriminative-stimulus effects of cocaine, resulting in overall rightward shifts of the cocaine dose-response functions.
