SKF-83566
Based on 3 publication(s) in Google Scholar
SKF-83566 is an orally active, blood-brain barrier-permeable D1/D5 dopamine receptor antagonist with a Ki 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. SKF-83566 acts as an inhibitor of the dopamine transporter (DAT) and adenylyl cyclase 2 (AC2). SKF-83566 competitively binds to DAT to inhibit dopamine reuptake and non-competitively inhibits AC2 activity, thereby reducing cAMP accumulation. SKF-83566 is used in research areas such as dopaminergic system mechanisms, learning and memory, targeted intervention for glioblastoma, AC2 pathophysiology, antiparasitic drug screening, and synaptic plasticity (the "gating effect").
