Safety Data Sheet (SDS):
Biological target: SKF-83959 HBr is a dopamine D1-like receptor partial agonist (Ki values are 1.18, 7.56, 920 and 399 nM for rat D1, D5, D2 and D3 receptors respectively). SKF-83959 HBr has been shown to potentiate agonist binding of the σ1 receptor.
In vitro activity: This pharmacological characterization study demonstrates that SKF-83959 is not a highly-biased, functionally selective D1 ligand. Its reported behavioral effects are attributed to its partial D1 agonism in conventional signaling pathways, resembling the well-known partial agonist SKF38393. SKF-83959 exhibits partial agonism (not antagonism) at adenylate cyclase and D1-mediated β-arrestin recruitment, but does not affect phospholipase C signaling in heterologous systems. Reference: Neuropharmacology. 2014 Nov;86:145-54. https://pubmed.ncbi.nlm.nih.gov/24929112/
In vivo activity: This study indicates that SKF-83959 might have complex effects on the brain and that its specific mechanisms and potential applications in cognitive disorders must be further investigated. In a rat model of schizophrenia, repeated SKF-83959 treatment increased signal amplitude and enhanced the spectral power of low frequency delta and theta oscillations in the hippocampus. In MAM rats, SKF-83959 inhibited spatial learning and induced a significant increase in thigmotactic behaviour.
