VK4-116

D3R Antagonist

VK4-116 is a selective antagonist of the Dopamine D3 receptor (D3R) with a Ki value of 6.84 nM. This compound effectively inhibits Oxycodone-induced hyperlocomotion and locomotor sensitization in mouse models, demonstrating its potential as a therapeutic agent for addiction-related behaviors. Furthermore, VK4-116 has been shown to prevent the acquisition of Oxycodone-induced conditioned place preference (CPP) in rat models, highlighting its applications in addiction research.
