SB 272183 is a highly potent dual 5-HT1A and 5-HT1B antagonists as potential antidepressant drug.

SB-272183 is a selective 5-HT1A, 5-HT1B and 5-HT1D receptor antagonist. In addition, SB-272183 is also a potent and selective ligand for 5-HT1A, 5-HT1B and 5-HT1D receptors in human recombinant and native tissues with pKi values of 8.0, 8.1 and 8.7, respectively. SB-272183 can be used in antidepressant research[1].

5-HT_1A Receptor: 8.0 (pKi); 5-HT_1B Receptor: 8.1 (pKi); 5-HT_1D Receptor: 8.7 (pKi)
