5-I-R91150 (orR93274) is a compound that acts as a potent and selectiveantagonist of5-HT2A receptors.[1] Its main application is as itsiodine-123radiolabeled form, in which it can be used inSPECT scanning[2] in humanneuroimaging studies, to examine the distribution of the 5-HT2A receptor subtype in thebrain, e.g. with respect tosex andage[3] and in adults withAsperger syndrome[4] orAlzheimer's disease.[5]

An alternative 5-HT2A receptor ligand also used in neuroimaging isaltanserin.
