rat cortex 5-ht2a receptor

Abaperidone is a potent 5-HT2A receptor and dopamine D2 receptor antagonist with an IC50 of 6.2 for 5-HT2A receptors and 17 nM for dopamine D2 receptors.Abaperidone is a potentially atypical anti-psychotropic compound that reduces basal hsp70 mRNA expression in rat striatum and prefrontal cortex. expression in the striatum and prefrontal cortex of rats.

AR-A 2 is a selective 5-HT1B receptor antagonist with high affinity to guinea pig cortex 5-HT1B 1D and recombinant guinea pig 5-HT1B receptors (Ki: 0.24 and 0.47 nM), exhibiting a 10-fold lower affinity to guinea pig 5-HT1D receptor (Ki: 5 nM).
