SKF-83566 is an orally active, blood-brain barrier-permeable D1/D5 dopamine receptor antagonist with a K_i value of approximately 0.4-0.56 nM. SKF-83566 modulates locomotor behavior and spatial memory by blocking D1 receptors and inhibits glioblastoma progression by targeting the DRD1/c-Myc/UHRF1 pathway.
