Background:

MDL 72832 hydrochloride is a potent and selective ligand for 5-HT1A receptor with pIC50 value of 9.1 [1].

The 5-HT1A receptor is a G protein-coupled receptor for endogenous neurotransmitter serotonin (5-HT) and mediates inhibitory neurotransmission.

MDL 72832 hydrochloride is a potent and selective ligand for 5-HT1A receptor [1]. Also, MDL 72832 exhibited affinity with pKD values of 6.32 and 6.34 for 5-HT1C and 5-HT1D receptors, respectively [1].

In rats, MDL 72832 inhibited 8-OH-DPAT-induced cardiovascular effects. In guinea-pigs, 8-OH-DPAT inhibited the contraction of the field-stimulated guinea-pig ileum in a concentration-dependent way. While MDL 72832 inhibited 8-OH-DPAT-induced neuronal inhibition. MDL 72832 is a ligand for 5-HT1A receptor with mixed antagonist and agonist properties [1]. In pre-satiated rats, (+) -MDL 72832 (1.0 mg/kg) stimulated food intake and (-) -MDL 72832 (0.03 mg/kg) significantly increased food intake [2]. In rats, MDL 72832 increased postsynaptic 5-HT1A receptors mediating hypothermia and exhibited agonist property [3].
